Abstract: To sufficiently improve the distortion stiffness of a vehicle body with minimized influence on comfort in an occupant space. A vehicle-body structure includes a floor panel constituting a floor of an occupant space including a seat on which a passenger sits, and a center frame disposed to be higher than and away from the floor panel at a vehicle-width-direction central portion of the occupant space and extending in a vehicle front-rear direction. The center frame is arranged at a downward tilt toward the vehicle rear side. A rear portion of the center frame is connected to the floor panel.

Abstract: A side vehicle body structure ensures rigidity and shock absorption performance of the body, avoids widening of the body, and smooths the flow of exhaust gas. Embodiments include an engine, an exhaust apparatus, and a rear pillar extending upward from a rear-side portion of a side sill extending in the vehicle front-rear direction. The exhaust apparatus is disposed along the vehicle front-rear direction on the vehicle-width-direction outer side relative to the side sill. An exhaust system member is located at a going-around portion, with respect to the rear pillar, from the front side to the rear side and from the outer side to the inner side in the vehicle width direction. The rear pillar has a cross section orthogonal to the vehicle up-down direction having a shape in which a portion between front and rear ends is located on the vehicle-width-direction outer side relative to these front and rear ends.

Abstract: Upper frames and a lower frame that connect a rear end of a coupled body composed of a side sill and a rear pillar and a rear side housing to each other are spaced apart in a vehicle up-down direction. An inclined angle at which a lower frame is inclined to be closer to a vehicle inner side toward a vehicle rear side is larger than inclined angles at which the upper frames are inclined to be closer to the vehicle inner side toward the rear side. A lower joined portion to which a rear end of the lower frame is joined is on a vehicle-width-direction inner side with respect to an upper joined portion in the rear side housing, which is composed of a single member including at least the lower frame rear-end joined portion, and the first and second upper frame rear-end joined portions, and extending therebetween.

Abstract: A rear vehicle-body structure of a vehicle capable of increasing the support rigidity of a rear suspension and the transmission efficiency of a rear-end collision load to the vehicle front side. A side sill has an upper closed cross-section portion. The upper closed cross-section portion includes a closed cross-sectional space extending in the vehicle front-rear direction. A linear connecting frame connecting a rear end of the upper closed cross-section portion to a rear side housing is between the rear end of the upper closed cross-section portion and the rear side housing. The connecting frame is inclined to be closer to a vehicle lower side as the connecting frame approaches the vehicle front side. The upper closed cross-section portion is inclined to be closer to an upper side as the upper closed cross-section portion approaches a vehicle rear side to correspond to an inclination angle of the connecting frame.

Abstract: An impact absorbing structure for a vehicle according to the present invention includes: a resin frame member extending in a vehicle front-rear direction and having an opening portion in a surface thereof on one side in a vehicle width direction; and a strut member disposed in the opening portion of the frame member. The frame member includes a frame body having the opening portion, and a rib protruding at least either upward or downward from the frame body and extending in the vehicle front-rear direction. The strut member is disposed between a pair of opening edges for defining an upper edge and a lower edge of the opening portion and at a position abuttable against the paired opening edges, when the frame member is deformed by input of a load at a time of oblique collision from upward or oblique collision from downward.
