A lower structure of a vehicle body rear part includes a spare tire housing formed on a rear floor, a rear cross member disposed in front of the spare tire housing to connect side frames, and a hook reinforcing member disposed in the center in the vehicle width direction on the lower surface of the spare tire housing and extending in the vehicle longitudinal direction. The front end portion of the hook reinforcing member is connected to the rear cross member, and the rear end portion thereof extends to the rear end portion of the rear floor. The side frame at the vehicle rear of the rear cross member is divided into a frame front part and a frame rear part in the vehicle longitudinal direction, and the hook reinforcing member is divided into a reinforcing member front part and a reinforcing member rear part in the vehicle longitudinal direction. The frame front part has a rigidity higher than that of the frame rear part, and the reinforcing member rear part has a rigidity higher than that of the reinforcing member front part, and the two division positions coincide with each other in the longitudinal direction.

Lower structure of vehicle body rear part

A lower structure of a vehicle body rear part, when receiving a load from a rear side of the vehicle, prevents deformation of a spare tire housing toward a front side of the vehicle and displacement of the front end of a spare tire toward the front side of the vehicle, and also facilitates the tipping up of a rear portion of the spare tire. In particular, a lower structure of a vehicle body rear parthas a spare tire housingformed in a rear floorof the vehicle body rear parta rear cross memberwhich joins paired side framesarranged respectively on a left side and a right side in a vehicle width direction, and which is provided at a location frontward of the spare tire housingand a hook reinforcementfor a tow hook, extending in a vehicle front and rear direction and arranged at a center, in the vehicle width direction, of a bottom surface of the spare tire housing, wherein a front end of the hook reinforcementis attached to the rear cross member, the hook reinforcementforms a closed cross section in cooperation with the rear floorand is formed such that the closed cross section is larger on a rear side than on a front side, and the hook reinforcementis divided into a reinforcement front portionand a reinforcement rear portion(FIG.).

A lower structure of a vehicle body rear portion, includes: a spare tire housing formed in a rear floor; a cross member joining paired side frames, and being provided at a location frontward of the housing; a reinforcement for a hook, being arranged at a center of the housing; and a bumper member provided at a rear end of the vehicle body, in which a front side of the reinforcement is attached to the cross member, the reinforcement forms a closed cross section so that the closed cross section is larger at a rear side than at a front side, the reinforcement includes front and rear portions obtained by dividing the reinforcement at a location corresponding to a center of a spare tire, and an upper side of a rear end of the rear portion is arranged below the bumper member and overlaps with the bumper member (FIG.).

Lower structure of vehicle body rear portion

A structure is in a lower part of a rear vehicle body. In this structure, each rear side memberis divided into a rear side member front partand a rear side member rear partin a front-to-rear direction of the vehicle, a cross memberbelow a spare tire housing is joined to the rear side member rear part, and a central part in a vehicle width directionof the cross memberbelow the spare tire housing extends rearward in the vehicle and is curved obliquely downward.

Structure for lower part of rear vehicle body

A bracket structure is in a vehicle body rear portion. In the bracket structure, an upper bracketand first and second lower bracketsandare disposed in such a manner as to be shifted to a right side or a left side in the vehicle width direction from an axis passing through a center of a spare tire housing, the second lower bracketis formed in a concave shape and a closed section is formed between the first lower bracketand the second lower bracketby superposing the first lower bracketand the second lower bracket, and the upper bracketis attached to a top surface of the rear floor panel, and the upper bracketand the first lower bracketare disposed so as to correspond to each other in a vertical direction.

Bracket structure in vehicle body rear portion

A lower structure of a vehicle body rear part includes a spare tire housing formed on a rear floor, a rear cross member disposed in front of the spare tire housing to connect side frames, and a hook reinforcing member extending in the vehicle longitudinal direction. The side frame at the vehicle rear of the rear cross member is divided into a frame front part and a frame rear part in the vehicle longitudinal direction, and the hook reinforcing member is divided into a reinforcing member front part and a reinforcing member rear part in the vehicle longitudinal direction. The lower structure is configured so that when a load F is applied from the vehicle rear to a vehicle body rear part, the side frame is deformed so as to be bent in an upward convex shape at a division position of the frame front part and the frame rear part, and also the rear floor and the hook reinforcing member are deformed so as to be bent in a downward convex shape at a division position of the reinforcing member front part and the reinforcing member rear part.

In a roof retractable type vehicle including a roof storage area, a roof storage mechanism for storing a roof, and a tonneau cover for opening and closing the roof storage area, the tonneau cover is connected to the vehicle body side via a mechanism in which the front end of the tonneau cover moves frontward and upward from the closed position and the rear end of the tonneau cover moves frontward, and the tonneau cover is retracted in an inclined posture to the front of the roof storage area. The tonneau cover includes a central member positioned in the center in the vehicle width direction and side members adjacent to both sides of the central member, and the side members and are connected swingably to the central member so that the side members can be retracted to the center side in the vehicle width direction.
