Each insertion hole 61 to 64 is formed in a long hole shape so as to extend in the vehicle front-rear direction. As shown in FIG. 6, when the battery 12 is fixed to the fixing plate 52, the bolts 67 to 70 on the lower surface of the battery 12 are respectively connected to the front end portions of the insertion holes 61 to 64 of the corresponding fixing plate 52. After inserting from the upper side, nuts 71 to 74 are screwed from the lower side and tightened.

  Thus, since the battery 12 is supported by the support member 32, use of the support member only for a battery can be abbreviate | omitted, and the increase in a number of parts can be suppressed.

  As shown in FIG. 1, the battery 12 attached to the support member 32 as described above is disposed across the vehicle front and rear sides of the dash panel 18. Therefore, the degree of freedom in weight distribution between the front wheel 2 and the rear wheel 4 is ensured, and an optimal front-rear weight distribution such as 6: 4 can be obtained. Therefore, it is possible to obtain good running performance and steering stability of the vehicle 1. Further, the front end portion of the battery 12 is disposed immediately after the vehicle on the drive shaft 14. Therefore, while avoiding interference between the battery 12 and the drive shaft 14, the battery 12 can extend as far as possible in front of the vehicle from the dash panel 18, which can contribute to an increase in battery capacity.

  Further, the battery 12 is accommodated in the front part of the vehicle rather than the step part 23 of the tunnel part 22 on the rear side of the dash panel 18, and the shock absorbing member 33 is rearward of the step part 23 of the tunnel part 22. Contained in the part. Therefore, the battery 12 and the shock absorbing member 33 can be arranged so as not to be exposed to the vehicle interior space 5 without raising the floor panel 20 or using a dedicated cover member. Therefore, it can be avoided that the vehicle interior space 5 is narrowed and the number of parts is increased while the battery 12 is disposed across the front and rear of the dash panel 18. Further, the battery 12 is disposed from the front end portion to the rear end portion of the tunnel portion 22. Therefore, a large capacity of the battery 12 can be secured by making maximum use of the space in the tunnel portion 22.

  Hereinafter, the movement of the battery arrangement structure at the time of the front collision of the vehicle 1 will be described with reference to FIGS.

  When the vehicle 1 collides forward, as shown in FIG. 7, first, the front side frames 25 and 27 and the sub frame 34 start to be crushed by the impact load. Then, the sub-frame 34 collides with the motor unit 10, and the motor unit 10 rotates to the vehicle rear side around the drive shaft 14 and moves to the vehicle rear side. Further, the sub-frame 34 collides with the steering shaft 16, and the steering shaft 16 moves to the rear side of the vehicle.

  Then, as shown in FIG. 8, the motor unit 10 and the steering shaft 16 collide with the battery 12, and the bolts 65 and 66 on the lower surface of the battery 12 come from the vehicle front end portions of the insertion holes 44 and 45 of the rear side member 38. The battery 12 is separated from the subframe 34 by sliding to the rear end side and detaching from the insertion holes 44 and 45. As a result, the bolts 67 to 70 on the lower surface of the battery 12 slide from the vehicle front end portion to the rear end portion side of the insertion holes 61 to 64 of the fixed plate 52, and the battery 12 is rearward of the battery support portion 43. Move relative to the side. At this time, the battery support portion 43 does not move. That is, the battery 12 moves to the vehicle rear side.

  Then, the battery 12 presses the impact absorbing member 33, which is restricted from moving to the vehicle rear side by the kick-up portion 21 and the No. 3 cross member 31, to the vehicle rear side, and the impact absorbing member 33 starts to be crushed. At this time, the vehicle rear portion from the step portion 13 of the battery 12 enters the vehicle rear portion from the step portion 23 of the tunnel portion 22. When the impact absorbing member 23 is crushed as described above, the impact load accompanying the movement of the battery 12 toward the rear side of the vehicle at the time of the front collision of the vehicle 1 is absorbed.

  Then, as shown in FIG. 9, after the front side frames 25 and 27 are broken, the sub-frame 34 is detached from the front side frames 25 and 27 as shown in FIG. Then, the shock absorbing member 23 is completely crushed and the movement of the battery 12 to the rear side of the vehicle is completed.

-Effect-
As described above, according to the present embodiment, the battery 12 is disposed across the vehicle front and rear sides of the dash panel 18, and the support member 32 that supports the battery 12 so as to be movable to the vehicle rear side when the vehicle 1 collides. Since the shock absorber 33 is disposed on the rear side of the member 32 and absorbs the shock caused by the movement of the battery 12 toward the rear of the vehicle, the impact load is applied to the battery 12 and the shock at the time of the front collision of the vehicle 1. It is possible to prevent the shock load from being absorbed by the absorbing member 33 and directly transmitting the impact load to the vehicle interior space 5 when the vehicle 1 collides.

  In addition, the No. 3 cross member 31 that extends in the vehicle width direction and restricts the movement of the shock absorbing member 33 to the rear side of the vehicle is provided on the rear side of the shock absorbing member 33. Using the No. 3 cross member 31, the impact load associated with the movement of the battery 12 toward the rear of the vehicle can be reliably absorbed by the impact absorbing member 33.

  Further, since the motor unit 10 is disposed on the front side of the battery 12 in the vehicle, the impact load can be quickly transmitted to the battery 12 and the shock absorbing member 33 via the motor unit 10 when the vehicle 1 collides.
