Abstract: Provided is a battery mounting part support structure of a vehicle, in which a pair of battery support legs can also be disposed at portions other than inside of a front side frame, which can stably support the pair of battery support legs and which can achieve reduction in weight. The battery mounting part support structure of the vehicle includes a front support leg 34 and a rear support leg 31, 32 that support a battery B and a coupling member 33 that couples the front support leg 34 and the rear support leg 32, and the front support leg 34 and the rear support leg 31, 32 are supported by an upper surface and a side surface 112 of a front side frame 11 on a front side and a rear side of the coupling member 33.

Abstract: A vehicle battery rotating structure is provided that allows a battery receptacle to be stably deformed at the time of a head-on collision to rotate a battery. A vehicle battery rotating structure 30 includes: a battery B that faces an engine-mounted part 12; a battery supporting face that is deformable into an inverted-V shape at the time of a head-on collision; a pair of battery locking pieces each of which is arranged on either side of the center in the front-rear direction of the battery supporting face; a pair of locking rods 41 that is locked in locking holes of the pair of battery locking pieces; and a pressure plate 42 that is connected to upper parts of the pair of locking rods 41.
