A lower structure for a hybrid automobile in which a high-voltage battery is disposed in a lower surface of a floor panel includes an engine exhaust system component which is disposed in front of the high-voltage battery in the lower surface of the floor panel and on one vehicle-width-direction side of a center in a vehicle width direction and high-voltage devices which are disposed in front of the high-voltage battery and on another vehicle-width-direction side of the center in the vehicle width direction. In-vehicle equipment is disposed between the high-voltage battery and the high-voltage devices, and the in-vehicle equipment is in an inclined state where an upper surface of the in-vehicle equipment is inclined in a front-rear direction such that the in-vehicle equipment has a shorter dimension in the front-rear direction than a dimension in a horizontal state where the upper surface becomes horizontal.

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 front suspension device comprises a suspension arm, one end of which has a front-wheel support portion to support a front wheel of a vehicle and the other end of which is positioned on an inward side, in a vehicle width direction, of the front-wheel support portion and has a vehicle-body attachment portion to be attached to a vehicle-body member of the vehicle and a damper supported at a damper support portion which is provided at a portion of the suspension arm which is positioned in the vicinity of the front-wheel support portion at a lower portion thereof and connected to the vehicle-body member at an upper portion thereof. The damper support portion of the suspension arm has a breakage ease portion to cause breakage of the suspension arm.

Front suspension device

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.

A subframe structure includes a pair of left and right front-rear frames each mounted with a lower arm; and a transverse member connecting front portions of the front-rear frames. The front-rear frames each includes a rear horizontal portion formed substantially horizontally, an inclined portion extending frontward and upward from a front end of the rear horizontal portion, and a front horizontal portion extending horizontally frontward from a front end of the inclined portion. The transverse member is jointed at left and right ends thereof to the front horizontal portions respectively corresponding to the left and right ends, a rear end of the front horizontal portion is disposed to be positioned frontward of a front end of an engine, and the front-rear frames are deformed into a Z shape in vehicle side view in an event of a front-end collision and thereby energy of the front-end collision is absorbed.

Subframe structure

A vehicle-body structure of an automotive vehicle comprises a frame which is provided at a side portion of a vehicle body to extend in a vehicle longitudinal direction, and a load absorption portion which is provided at a front face of a tip portion of the frame to protrude forward, wherein the load absorption portion includes an inclination face portion which protrudes outward, in a vehicle width direction, relative to the frame and a tip face of which extends obliquely forward and inward.
