Abstract: A bonding structure of dissimilar metal members, including a first metal member, a second metal member, and a brazing filler metal, wherein the brazing filler metal bonds a bonding end surface of the first metal member and a bonding end surface of the second metal member, and any one or both of the following conditions (1) and (2) are satisfied: (1) at least a part of the bonding end surface of the first metal member in a thickness direction of the first metal member is an inclined surface inclined with respect to a plane perpendicular to the thickness direction of the first metal member, and (2) at least a part of the bonding end surface of the second metal member in a thickness direction of the second metal member is an inclined surface inclined with respect to a plane perpendicular to the thickness direction of the second metal member.

Abstract: A tunnel reinforcing member is attached to a front floor tunnel. Second upper wall and second side walls of the tunnel reinforcing member are connected to a first upper wall and first side walls of the front floor tunnel, respectively, such that spaces are formed between second edge portions of the tunnel reinforcing member and first edge portions of the front floor tunnel. A rear portion of the first upper wall of the front floor tunnel faces a lower wall of a cross member with a kick-up part in between. A rear portion of the second upper wall of the tunnel reinforcing member inclines upwards and rearwards so as to be separated apart from the first upper wall of the front floor tunnel and faces a section reinforcing member fixed to the cross member with the kick-up part in between.

Abstract: A battery-fixing structure includes a battery-receiving portion provided by depressing downward a floor panel in a rear part of a vehicle body, the battery-receiving portion including a battery-supporting wall member; an upper reinforcing plate having a recess that is depressed downward; and a lower reinforcing plate having a first projection that is raised upward. The battery-supporting wall member is held between the upper reinforcing plate and the lower reinforcing plate. The recess, the battery-supporting wall, and the first projection are joined to one another in such a manner as to overlap one another in a top-bottom direction. A battery is fixed to the upper reinforcing plate with a fixing member.

Abstract: A vehicle body structure for an automobile includes a damper base connected to an outer wall of a rear side frame in a vehicle width direction on a rear side of a cross member and including a first bead projecting inward in the vehicle width direction and extending in an up-down direction and a damper support portion projecting outward in the vehicle width direction disposed on both sides of the first bead in a front-rear direction, a rear wheel house having a second bead extending in the up-down direction to overlap with an inner surface of of the first bead in the vehicle width direction, and a gusset having a third bead extending in the up-down direction to overlap with the inner surface of the first bead in the vehicle width direction and connected to an upper wall of the rear side frame.

Abstract: A vehicle body structure for an automobile includes left and right rear side frames that extend in a front-rear direction, a rear floor that connects the left and right rear side frames to each other and that includes a lower surface having a rear portion where a compressor for air suspension is supported, a compressor housing that covers the compressor, and left and right rear braces that are disposed so as to form a V shape having an opening on a front side in top view and that couple front portions of the left and right rear side frames to the compressor housing.

Abstract: A vehicle body rear structure includes a floor brace extending outward in a vehicle width direction in an inclined manner from a front floor, and a rear brace extending inward in the vehicle width direction in an inclined manner from a rear end portion of the floor brace. A rear end portion of the rear brace is connected with a support bracket. A front end portion of the rear brace and the rear end portion of the floor brace are connected with a left rear frame via a connecting member. The floor brace and the rear brace are arranged in a substantially V-shape in plan view.
