Further, the service plug 36 is positioned forward of the rear end of the protective member 40 in the vehicle front-rear direction. With this configuration, it is possible to prevent the feet of a passenger sitting on the rear seat (not shown) from colliding with the service plug 36 .

(Modification)
Although the description of the embodiment is finished above, the aspect of the present invention is not limited to this embodiment. For example, the protection member 40 may be connected to the skeleton member 10 other than the backbone 16 and the cross member 15 as long as it is configured to function as one of the vehicle body structures. Moreover, the protective member 40 does not have to function as a console bracket that supports the center console 25 .

Further, the leg-side flange portions 43F formed on the pair of rear leg portions 43B may be connected to any position of the top plate portion 41 without being limited to the top plate-side flange portion 41F. Also, the leg-side flange portion 43F may be omitted from the protective member 40 . Further, the top plate-side flange portion 41</b>F may be omitted from the protection member 40 if the service lid 37 can be rendered immovable without using the holding member 38 .

Further, the pair of rear leg portions 43B need not have the rear fixing portion 431B extending outward in the vehicle width direction as long as they can be connected to one of the frame members 10 . Also, the pair of rear leg portions 43B may extend linearly from the lower end portion to the top plate portion 41 .

FIG. 9 is a rear view showing a modification of the protective member 40. FIG. As illustrated, the protective member 40 may have a connecting portion 44 that connects the lower ends of the pair of rear leg portions 43B. With this configuration, the connecting portion 44 can further increase the rigidity around the pair of rear leg portions 43B in the vehicle width direction. As a result, deformation of the peripheral portion of the service plug 36 can be better suppressed when a side collision occurs in the vehicle.
