A lower structure for a vehicle includes a battery unit which is provided under a vehicle body floor, a frame member which extends in a front-rear direction on a vehicle-width-direction outer side of the battery unit, a high-voltage cable which extends forward from a front portion of the battery unit, and a fixing member which fixes a rear portion of the battery unit to the frame member, and the fixing member is configured to be fractured when an inward collision load in a vehicle width direction is input to a position in front of a position of a center of gravity of a first battery unit.

Lower structure for vehicle

A lower structure of a vehicle may include a transmission disposed in a floor tunnel, a rear propeller shaft that transmits power from the transmission to rear wheels, and left and right battery units disposed on the left and right sides of the floor tunnel, in which a rear portion (transfer) of the transmission is disposed in proximity to the portions on the front side and the upper side of the battery units, and inner protectors that cover inner side surface portions in the vehicle width direction of the battery units from the inner side in the vehicle width direction may be mounted to the front end portions of the inner side surface portions.

Lower structure of vehicle

A vehicle may include a propeller shaft that extends from a transmission toward a vehicle rear side and left and right battery units disposed below floor panels disposed on the left and right sides of a floor tunnel. The propeller shaft may include a first shaft portion connected to the transmission and a second shaft portion connected to the first shaft portion via a universal joint. The left and right battery units may have inner side surface portions that face the inner side in the vehicle width direction, respectively. Planar protectors that cover the portions of the inner side surface portions on the vehicle rear side of the universal joint may be mounted to the battery units, respectively.
