Abstract: A deck cover is openably provided at a vehicle-body rear portion positioned in back of a cabin. A top portion of a rear wheelhouse is provided at the vehicle-body rear portion. This top portion is configured to be displaced upward, relative to a vehicle-body rear end portion, such as a rear bumper or a rear end panel, by vehicle-body deformation caused by a vehicle rear collision. The deck cover is supported at a position of the vehicle-body rear portion which is located vertically above or in front of the top portion of the rear wheelhouse such that the deck cover is elevated in accordance with upward displacement of the top portion when the vehicle-body rear portion receives a rear-collision load.

Abstract: A rear vehicle-body structure absorbs an impact from vehicle rear even when an installed amount of the batteries is increased by including a rear side frame which extends in a vehicle front-rear direction, a rear-side cross member which is arranged such that a front portion of the rear side frame abuts the rear-side cross member from vehicle rear, the rear-side cross member extending in a vehicle width direction, a pair of left and right side sills which are spaced apart, by predetermined distances, from the front portion of the rear side frame to vehicle-width-direction outer sides and extend in the vehicle front-rear direction, and a rear-side battery frame which extends in the vehicle width direction in the vehicle rear of a battery and in vehicle front of the rear side frame. The rear-side battery frame is mounted on the left and right side sills and on the rear-side cross member.

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.
