Abstract: A seat back table attached to a rear surface of a seat back of an in-vehicle seat includes a base plate fixed to the rear surface of the seat back, and a table plate that is opened and closed by swinging with respect to the base plate, and, in this seat back table, a gap to which a fingertip can be inserted is provided between at least a portion of a peripheral edge of the base plate and the seat back, and at least the portion of the peripheral edge of the base plate functions as a grip portion that is capable of being gripped by a user.

Abstract: A joint structure of a bumper reinforcement and a side member, the joint structure comprising: a bumper reinforcement that is provided at a vehicle front-rear direction end portion of a vehicle so as to extend in a vehicle width direction, and that includes: a vertical wall and a pair of horizontal walls; a left and right pair of side members that are respectively provided at the vehicle inner side of the bumper reinforcement so as to extend in the vehicle front-rear direction with leading ends of the side members fastened to the vertical wall of the bumper reinforcement; and fastening extensions that are provided at the respective leading ends of the side members, that project out toward a vehicle width direction outer side with respect to a respective side member, and that are fastened to at least one of the horizontal walls of the bumper reinforcement.

Abstract: A bumper reinforcement includes a body part extending in a vehicle width direction, and a terminal part, which extends in the vehicle width direction, is attached to an end part of the body part in a longitudinal direction, and is joined to the body part in a state of being superimposed on the end part of the body part. Rigidity of the end part of the body part in the longitudinal direction is lower than rigidity of a center part of the body part in the longitudinal direction.

Abstract: A vehicle substructure includes an indoor reinforcement disposed on the opposite side of a floor panel from a front side member. The indoor reinforcement includes an upper wall portion facing the floor panel and extending in a front-rear direction of a vehicle, a pair of side wall portions extending downward from respective outer edges on both sides of the upper wall portion in a width direction of the vehicle, and a pair of flange portions extending outwards from respective lower edges of the side wall portions with lower surfaces of the flange portions fixed to an upper surface of the floor panel. The upper wall portion has flat plate-shaped flat portions and a ridge portion protruding from the flat portions toward an upper side of the vehicle or a lower side of the vehicle and extending in the front-rear direction of the vehicle.
