Fit into 39. In this state, the clip support portions 42 and 42 of the covers 4 and 4 are completely fitted inside the attachment clips 5 and 5, and the attachment clips 5 and 5 are firmly locked to the body panel to attach the assist grip. To complete.

  When the assist grip is used, the user rotates the grip body 1 downward with respect to the left and right hinge portions 2 and 3 as shown in FIG. The grip body 1 is pulled downward at the center by the user. At this time, the torsion coil spring 6 has its other end 62 turned by the rotation of the locking recess 11 a of the hinge recess 11 in the grip body 1. It is twisted against the force and moves in the guide groove 73 of the spring case 7. As a result, the grip body 1 rotates downward against the torsion spring force, and the grip body 1 is used when the user grips the grip body 1.

  At this time, the load applied by the user is applied to the inner bosses 24 and 34 and the outer bosses 25 and 35 of the hinge portions 2 and 3 via the grip body 1, but the downward load is mainly large with respect to the inner bosses 24 and 34. Applied.

  However, this load is received by the inner bosses 24 and 34 projecting from the thicker inner support pieces 22 and 32, and a spring is used as a support member between the inner support pieces 22 and 32 and the outer support pieces 23 and 33. Since the case 7 or the oil damper 8 is inserted, the inner bosses 24, 34 and the inner support pieces 22, 32 can be reliably supported without being bent.

  Also, the load at the time of use is applied mainly to the upper portion of the outer bosses 25 and 35, but the notches 25a and 35a provided in the outer bosses 25 and 35 are only the lower end portions of the outer bosses 25 and 35. Since the boss hole wrap amount with respect to is sufficiently secured, the outer bosses 25 and 35 can reliably support the load in use at the upper part thereof. Similarly to the above, since the spring case 7 or the oil damper 8 is inserted between the inner support pieces 22 and 32 and the outer support pieces 23 and 33 as a support member, the outer bosses 25 and 35 receive a load. The outer support pieces 23, 33 are prevented from being bent and deformed.

  On the other hand, when the user removes his / her hand from the grip body 1 in the use state of the assist grip, the grip body 1 is attached upward (counterclockwise in FIG. 2) from the other end 62 of the torsion coil spring 6 in the spring case 7. Under the influence of the force, it rotates in the same direction and returns to the non-use state (solid line position in FIG. 2). At this time, the oil damper 8 acts to brake the rotation of the grip body 1, and the grip at a low speed. The main body 1 will return to the non-use position.

  In the above embodiment, the oval boss insertion portion 32a, the guide groove 32b, and the inclined surface 32c are provided inside the inner support piece 32 of the pair of inner support pieces 32 and outer support pieces 33 of the hinge portion 3. Instead of the inside of the inner support piece 32, they can be provided inside the outer support piece 33. In this case, the oval boss portion of the oil damper is provided at the end opposite to the end of the inner cylinder of the oil damper 8 in FIG. Moreover, the hinge part which attaches an oil damper can also be made into the hinge part on the opposite side to the said embodiment.
