Further, the battery tray, strut tower, dash panel and the reinforcing member form a structure having a predetermined rigidity in a substantially rectangular cross section along the vehicle width direction. Therefore, the rigidity of the battery attachment portion can be improved together with the vehicle body rigidity.

Further, since the reinforcing member is bridged and fixed between the upper surface of the dash panel and the upper surface of the strut tower, the mounting of the battery body is completed. It is possible to easily assemble without using the holding member, each connecting rod, and the nut, and to improve the assembling workability while suppressing an increase in the number of parts.

According to the second aspect of the present invention, the battery tray is connected to a heat shielding member provided between the strut tower housing and a dash panel. Therefore, for example, if the heat shield member is extended and fixed to the dash panel, the surface for supporting the battery tray is further increased, so that the support rigidity of the battery body and the rigidity of the vehicle body can be improved. .

According to the third aspect of the present invention, the battery tray, the lower body panel of the strut tower housing, and the dash panel form a substantially closed cross-sectional shape. The opening of the cross section extends along the vehicle width direction.

For example, the vehicle body lower panel is a hood ridge panel or a side member.

The direction of formation of the closed section is such that the opening direction is inclined toward the front of the vehicle, and the rear end of the closed section is deflected and abuts on the sill portion below the front pillar.

For this reason, in addition to the above operation, the input from the front direction of the vehicle is transmitted to the sill below the front pillar. Since the sill portion has high rigidity due to the formation of the closed cross-sectional shape, it is possible to efficiently absorb a collision load through the closed cross-section forming portion having a high vehicle body reaction force.

Further, by improving the rigidity of the sill portion, the rigidity of the root portion of the side member is also improved, and the torsional reaction force against the thrust applied to the strut tower housing can be increased.

According to the fifth aspect of the present invention, since the battery-side side surface of the heat shielding member is in contact with the side surface of the battery body, the battery body further disperses the supporting stress. In addition to the upper and lower surfaces, the surface can be increased by one surface to improve the support stiffness.
