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 grille shutter unit which is provided with plural shutters extending in a vehicle width direction is attached to a frame-shaped shroud, a center stay is provided to extend in a vertical direction and connect a central portion, in a width direction, of a shroud upper and a central portion, in the width direction, of a shroud lower, the grille shutter unit is attached to a back-face side of the shroud, and an actuator (driving actuator) for opening/closing the shutters is arranged at a back-face side of the center stay.

Grille shutter attaching structure of automotive vehicle

There are provided a front side frame having a closed cross section extending in a vehicle longitudinal direction and including a mount-bracket attachment part for attaching a PT mount bracket provided at a PT mount for supporting a powertrain and a crash can attached to a front end of the front side frame. The front side frame includes a compressive-deformation part which is configured to be compressively deformed in a vehicle frontal collision and extend rearward from the front end, having substantially the same sectional shape as the crash can. A gusset member for preventing shearing deformation of the closed cross section of the front side frame is provided at a portion of the front side frame between the mount-bracket attachment part and the compressive-deformation part.

Front vehicle-body structure of vehicle

A grille shutter unit which is provided with shutters and a frame which pivotally supports shutter shafts provided at the shutters is attached to a frame-shaped shroud which supports heat exchangers. The grille shutter unit is configured to be attached to the shroud from a back-face side of the shroud at a position located in front of the heat exchangers.
