Also good. In the above embodiment, the flange-like portions 36B2 and 36C2 are extended in opposite directions. However, the flange-like portions 36B2 and 36C2 may be extended in directions approaching each other.

  Furthermore, in the said embodiment, although the positioning bracket 36 was set as the structure provided with the four ridgelines L1-L4, this invention is not restricted to this, The number of ridgelines can be changed suitably. Moreover, you may make it the structure by which the ridgeline was abbreviate | omitted.

  Moreover, in the said embodiment, although the positioning bracket 36 was set as the structure provided with the upper wall 36A, the left wall 36B, and the right wall 36C, the invention which concerns on Claim 1 is not restricted to this, A positioning bracket does not have an electrical storage pack. What is necessary is just to have the function to position to the left-right direction with respect to a vehicle body, and the function to suppress a deformation | transformation of the bracket main body 34 at the time of a rear collision, The shape can be changed suitably.
