Abstract: The disclosure provides a vehicle body rear structure, which can reduce damage to the vehicle during a collision from the rear. The vehicle body rear structure includes a chassis rear, a hook reinforcement part fixed to a lower surface of the chassis rear; and a hook fixed on a back side of the chassis rear through the hook reinforcement part, in which the hook reinforcement part includes a plurality of part members independent from each other, the plurality of part members are connected in series and joined in a front-back direction of the vehicle to form a joint boundary part, and the joint boundary part is disposed with a weakened part on a side close to the chassis rear.

Abstract: A vehicle body rear part structure includes a rear frame and a beam member. The rear frame has: a first inner bead, a first outer bead, a second inner bead, and a second outer bead. The first inner bead and the first outer bead are formed on an inner wall and an outer wall, respectively, in a region close to the beam member. The second inner bead and the second outer bead are formed on the inner wall and the outer wall, respectively, in a region that is separated to a vehicle body frontward direction from the first beads. The first outer bead is formed to have a higher fragility than the first inner bead.

Abstract: A vehicle body rear section includes a rear floor pan (11), a floor pan reinforcement member (20), and a towing load receiving section. The rear floor pan (11) has an upper surface to which the spare tire (16) is fixed. The floor pan reinforcement member (20) is fixed to a lower surface of the rear floor pan (11). The towing load receiving section protrudes downward from a rear section of the rear floor pan (11). The floor pan reinforcement member (20) extends at least partially from a support position of the towing load receiving section toward a front side of a fixed position of the spare tire (16). An easy-deformable portion (22) with lower bending strength than that of front and rear regions is provided in front of the fixed position of the spare tire (16) in a reinforcement region of the rear floor pan (11).

Abstract: A vehicle rear structure includes a spare tire bracket which has a longer rear section than a front section thereof in the vehicle with respect to a spare tire fixing portion, a spare tire fixed to the spare tire fixing portion, and reinforcement member having a second inclination reinforcing portion extending upward from a rear section of a rear floor pan towards the front of the vehicle. The spare tire bracket has a first easy bending section provided behind the spare tire fixing portion in the vehicle. The reinforcement member has a second easy bending section provided behind the spare tire fixing portion in the vehicle.

Abstract: This vehicle body rear structure includes a tire pan provided to protrude downward from a floor of a vehicle rear section and including a spare tire fixing portion configured to fix a center portion of a spare tire, and a jack base provided on the tire pan, and the jack base extends downward from the tire pan on a rear side with respect to a vehicle body, and has a front end portion continuously extending from the spare tire fixing portion to a front side of the vehicle body.

Abstract: A vehicle body rear part structure includes a rear frame and a beam member. The rear frame has: a first inner bead, a first outer bead, a second inner bead, and a second outer bead. The first inner bead and the first outer bead are formed on an inner wall and an outer wall, respectively, in a region close to the beam member. The second inner bead and the second outer bead are formed on the inner wall and the outer wall, respectively, in a region that is separated to a vehicle body frontward direction from the first beads. The first outer bead is formed to have a higher fragility than the first inner bead.
