Abstract: A vehicle includes a drive battery unit including a battery unit case, a pair of left and right battery side frames, and a plurality of fixing members. The drive battery unit is fixed to the vehicle. The battery unit case includes a left side wall and a right side wall. One of the pair of left and right battery side frames is disposed on a left side of the left side wall of the battery unit case. Another of the pair of left and right battery side frames is disposed on a right side of the right side wall of the battery unit case. Each of the fixing members is fixed to the pair of left and right battery side frames, and a length of each of the fixing members in the front-rear direction is longer than a length thereof in the vehicle width direction.

Abstract: A vehicle substructure is capable of changing arrangement in a battery case depending on the type and/or size of batteries. The vehicle substructure includes: a battery case having a battery housed therein and including a bottomed case pan having an opening at a top thereof, and a case cover to close the opening of the case pan; a floor panel positioned above the battery case; a pair of right and left seat frames fixed to a top surface of the floor panel; and a battery cross member extending in a vehicle width direction in the battery case, fastened to the pair of right and left seat frames and fixed to the floor panel, wherein the pair of right and left seat frames extend in a vehicle front-rear direction and are provided with mounting holes in the vehicle front-rear direction for fastening the battery cross member.

Abstract: A vehicle substructure is capable of efficiently transmitting a load inputted from a front subframe or a front suspension mechanism. The vehicle substructure includes a battery case having a battery housed therein, wherein the battery case includes a bottomed case pan having an opening at a top thereof, and a case cover to close the opening of the case pan, wherein the battery caser is partly formed of a cast member which is arranged at a front end of the case cover and coupled to a rear end of the front subframe.

Abstract: A vehicle substructure prevents a side sill, when a load is inputted, from being turned. The vehicle substructure includes a battery case having a battery housed therein. The battery case includes a bottomed case pan having an opening at a top thereof, and a case cover to close the opening of the case pan. The case cover vertically has a top plate at a top, a bottom plate at a bottom, and partitions disposed between the top and bottom plates to couple the top plate with the bottom plate and linearly extending in a vehicle width direction so as to be substantially in parallel to each other. Both ends in the vehicle width direction of the case cover are connected to a pair of right and left side sills disposed on both the right and left sides in the vehicle width direction and extending in a vehicle front-rear direction.

Abstract: A valve protection structure for a vehicle includes: side members; a hydrogen tank disposed between the side members; and a valve member installed to project from a vehicle-widthwise end face of the hydrogen tank. The side member has a convex member projecting inward in the vehicle widthwise direction from an inner wall part, the convex member is placed at a position offset with respect to the valve member and opposite the hydrogen tank in the vehicle widthwise direction, and a vehicle-widthwise distance between a tip part of the convex member and a portion of the hydrogen tank opposite the tip part of the convex member in the vehicle widthwise direction is set shorter than a vehicle-widthwise distance between a tip part of the valve member and a portion of the side member opposite the tip part of the valve member in the vehicle widthwise direction.

Abstract: A vehicle rear structure includes a side sill joined to a rear frame via an outrigger, a sub-frame mounted on the rear frame from below, and a fuel tank mounted on the sub-frame. The sub-frame is provided with a load transmitting member that opposes the outrigger. An impact load applied to the sub-frame is transmitted to the outrigger via the load transmitting member. The transmitted impact load is distributed to the two components, the rear frame (specifically, front frame section) and the side sill via the outrigger.

Abstract: A vehicle body side portion structure includes a side sill that, at a side portion of a vehicle body, extends in a front-rear direction of the vehicle body; a rear side floor panel that is joined to a rear portion of a floor panel of the vehicle body and extends towards a rear of the vehicle body, and that extends in a vehicle width direction and is joined to the side sill; and a rear middle floor panel that is provided at an inner side of the rear side floor panel in the vehicle width direction and covers an energy storage. A vertical wall portion is provided at an outer side of the rear middle floor panel in the vehicle width direction. The rear side floor panel is joined to an outer side of the vertical wall portion in the vehicle width direction and includes a weakened portion.
