As shown in FIGS. 1 and 2, the hook member 45 has a pair of hook-shaped hook pieces 45b and 45c that are spaced apart in the vehicle height direction and are integrally formed on the upper and lower inner wall surfaces of the holder portion 45a. The two hook pieces 45b and 45c are branched by a slit 45d formed by being spaced apart in the vehicle height direction. The hook member 45 has a hook-shaped opening side facing the hook member 44.

  As shown in FIG. 6, the hook member 45 is integrally formed with a square plate-like seat portion 47 as an opposing wall portion protruding outward from the tip of the holder portion 45 a that faces the hook member 44. The seat portion 47 is formed with a columnar guide pin 47a that protrudes toward the rear side of the vehicle (side away from the hook member 44). The protrusion length of the seat portion 47 in the vehicle width direction (vehicle outer side) is set to be equivalent to the protrusion length of the holder 42 (the lid wall portion 42b and the bottom wall portion 42c) in the vehicle width direction (vehicle inner side). The length in the vehicle width direction including the hook member 45 and the seat portion 47 is set to be equal to the length in the vehicle width direction of the bottom wall portion 41b or the lid wall portion 43a. In the hook member 45, the seat portion 47 is inserted into the holder 42, the holder portion 45a is sandwiched between the lid wall portion 43a and the bottom wall portion 41b, and the seat space 47 is also slidable in the vehicle longitudinal direction. Is housed inside. At this time, the hook member 45 is restricted by the flanges 41d and 43c and is prevented from dropping out to the vehicle interior side.

  As shown in FIG. 3, the seat 47 (guide pin 47a) faces the side wall 43b in the vehicle front-rear direction, and is inserted and guided by the guide pin 47a between the seat 47 and the side wall 43b.

  Here, a substantially cylindrical locking piece 48 having a center line extending in the vehicle height direction is fixed to the terminal 33a. The locking piece 48 is hooked on the hook member 44 in such a manner that both ends in the axial direction are locked to the hook pieces 44b and 44c, and the terminal 33a (front cable 33) connected to the locking piece 48 is slit 44d. And the interference with the hook member 44 is avoided. Similarly, a substantially cylindrical locking piece 49 having a center line extending in the vehicle height direction is fixed to the terminal 34a. The locking piece 49 is hooked to the hook member 45 in such a manner that both ends in the axial direction are locked to the hook pieces 45b and 45c, and the terminal 34a (rear cable 34) connected to the locking piece 49 is a slit. The interference with the hook member 45 is avoided by passing through 45d.

  That is, the locking pieces 48 and 49 can swing with respect to the hook members 44 and 45 when the terminals 33a and 34a run idle in the slits 44d and 45d. The front cable 33 and the rear cable 34 are allowed to swing the locking pieces 48 and 49 with respect to the hook members 44 and 45, so that an excessive bending load is suppressed. The front cable 33 and the rear cable 34 are basically connected to a cable terminal connecting member 40 (hook members 44 and 45) arranged immediately below the load roller 22 and so on, so It is routed to the side. The front pulley 17 and the rear pulley 18 are also arranged below the center rail 13 in the vehicle height direction.

  Next, how the locking pieces 48 and 49 are assembled to the hook members 44 and 45 (cable terminal connecting member 40) will be described. As described above, the space between the hook members 44 and 45 accommodated in the accommodation space S is open to the inside of the vehicle. Therefore, the through-hole 42d of the holder 42 also has a central portion in the vehicle front-rear direction that opens to the inside of the vehicle via the hook members 44 and 45. In such a configuration, when the locking pieces 48 and 49 are assembled to the hook members 44 and 45, the jig 90 is used prior to this. As shown in FIG. 6, the jig 90 is formed of, for example, a resin material, and has a flat plate-like pressing piece portion 91 that has a cross-sectional shape equivalent to the outer shape of the through hole 42 d and protrudes toward the inside of the vehicle. In addition, it has a grip portion 92 that extends in a substantially T-shape from the base end portion disposed on the vehicle outer side of the pressing piece 91 to the vehicle outer side. A guide portion 91a that is gradually widened from the distal end toward the proximal end is formed at the distal end portion of the pressing piece portion 91. The distance between the seats 46 and 47 when the coil springs 51 and 52 are elastically restored is longer than the length of the distal end of the guide portion 91a in the longitudinal direction of the vehicle and the proximal end of the guide portion 91a. It is set shorter than the length.

  Therefore, when the pressing piece 91 of the jig 90 is gripped and the pressing piece 91 is inserted into the through hole 42d from the outside of the vehicle, the distance between the seats 46 and 47 is guided by the guide 91a. Spreads (lengthens) against the urging force of 52. As a result, the distance between the hook members 44 and 45 is also increased, and the opening amount to the vehicle inner side between the hook members 44 and 45 is increased.

  In this state, the locking pieces 48 and 49 are inserted into the openings between the hook members 44 and 45 from the inside of the vehicle while passing the cables 33 and 34 through the slits 44d and 45d. When the locking pieces 48 and 49 are released with the locking pieces 48 and 49 facing the hook-shaped openings of the hook members 44 and 45, the locking pieces 48 and 49 that are pulled by the tension of the cables 33 and 34. Is inserted into the hook members 44 and 45 and is hooked thereon.

  Next, when the pressing piece 91 is pulled out from the through hole 42d, the coil springs 51 and 52 are elastically restored by being released from the pressing piece 91, and the cables 33 and 34 are hooked so as to apply a tension for preventing looseness. The members 44 and 45 are biased.

  As described above, in the present embodiment, the locking pieces 48 and 49 are connected to the hook members 44 and 45 in a state where the opening between the both hook members 44 and 45 is widened in advance using the jig 90, that is, in a state where the work space is widened. As a result, the workability is improved.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) In the present embodiment, the hook members 44 and 45 (and the connecting portions between the hook members 44 and 45 and the terminals 33a and 34a) and the coil springs 51 and 52 that bias the hook members 44 and 45 are vehicles. By arranging in the width direction (perpendicular to the extending direction of the cables 33 and 34), the arrangement space of the tension mechanisms 40a and 40b in the extending direction of the cables 33 and 34 can be further reduced.

  (2) In the present embodiment, the tension mechanisms 40a and 40b are disposed directly below the load roller 22 (and the center rail 13), etc., so that the cables 33 and 34 locked to the hook members 44 and 45 are connected. The terminals 33a and 34a are also arranged directly below the road roller 22 and the like. Therefore, the displacement amount of the movement trajectory of the cables 33 and 34 with respect to the load roller 22 and the like can be reduced as a whole, and the restriction on the degree of freedom of arrangement of the cables 33 and 34 can be further reduced.

  In particular, the arrangement space of the tension mechanisms 40a and 40b in the extending direction of the cables 33 and 34 is further miniaturized, and the range of the tension mechanisms 40a and 40b (cable terminal connecting member 40) in the vehicle longitudinal direction is a guide. Since the roller unit 16 is within the range of the direction, the moving range of the guide roller unit 16 in the vehicle longitudinal direction along the center rail 13 is not restricted by the tension mechanisms 40a and 40b. Therefore, for example, the front pulley 17 does not need to be shifted in the extending direction of the center rail 13 (curved portion 13b) so that the moving range of the guide roller unit 16 in the vehicle longitudinal direction is not restricted by the tension mechanism. The amount of protrusion of 17 to the vehicle inner side can be suppressed. Or in order to suppress the protrusion amount to the vehicle inner side of the front pulley 17, it is not necessary to reduce the moving range of the guide roller unit 16 in the vehicle front-rear direction, that is, the opening amount of the slide door 20.

  (3) In the present embodiment, the terminals 33a and 34a are formed by the cables 33 and 34 being passed through the slits 44d and 45d, and the locking pieces 48 and 49 being swingably hooked on the hook members 44 and 45, respectively. Since swinging is allowed, for example, the structure of the tension mechanisms 40a and 40b can be simplified as compared with a case where the entire tension mechanism is connected to the guide roller unit 16 (sliding door 20 side) so as to be swingable. Further, for example, the rotation engagement pin set in the tension mechanism of Patent Document 1 can be omitted, and the tension mechanism (sleeve member) in which the engagement pin extends extends in the radial direction (vehicle height direction). , It can be made smaller.

  (4) In the present embodiment, the tension mechanisms 40a and 40b include a pair of seat portions 46 and 47 that are spaced apart from each other in the vehicle longitudinal direction (the urging direction of the coil springs 51 and 52). If the jig 90 having the guide portion 91a is inserted between the pair of seat portions 46 and 47 against the urging force of the coil springs 51 and 52, the separation distance between the seat portions 46 and 47 gradually increases. Thereby, the separation distance between the hook members 44 and 45 in which the seat portions 46 and 47 are integrally formed can be increased. Therefore, when the locking pieces 48 and 49 are hooked on one hook member 44 and 45, a wider space can be secured between the other hook members 44 and 45, and the tension mechanisms 40a and 40b can be secured. The assembling property of the cables 33 and 34 can be improved. Further, when removing the locking pieces 48, 49 from one hook member 44, 45, a larger space can be secured between the other hook members 44, 45, and the number of work steps required for inspection and repairs Can be reduced.

  (5) In this embodiment, when the locking pieces 48, 49 are hooked on the hook members 44, 45, a very simple shape having a guide portion 91a that is gradually widened from the distal end toward the proximal end. By using the tool 90, the separation distance between the pair of seats 46 and 47 can be increased.

In addition, you may change the said embodiment as follows.
In the above-described embodiment, the bottom wall portion 41b, the lid wall portion 43a, and the holder 42 may be divided into two in the vehicle front-rear direction so that the pair of hook members 44, 45 and the like are individually accommodated.

  In the above-described embodiment, the hook members 44 and 45 and the coil springs 51 and 52 may be superposed in other directions such as the vehicle height direction as long as they are orthogonal to the extending direction of the cables 33 and 34. Good.

  In the above embodiment, two cables, the front cable 33 and the rear cable 34, are used, but one cable may be used. In this case, one terminal of the cable corresponds to the terminal 33a, and the other terminal corresponds to the terminal 34a.

  In the embodiment, the tension mechanisms 40a and 40b are connected to the guide roller unit 16 supported by the slide door 20, but may be connected to an appropriate member (such as a bracket) on the slide door 20 side.

In the embodiment, the driving member 30 may be fixed to the slide door 20 side, and the tension mechanisms 40a and 40b may be connected to the vehicle body 10 side.
In the above embodiment, the guide rail and the guide roller member related to the opening / closing drive of the slide door 20 by the driving member 30 are not limited to the center rail 13 and the guide roller unit 16, for example, the upper rail 11 and the guide roller unit 14. Alternatively, the lower rail 12 and the guide roller unit 15 may be used.
