Abstract

A rear structure of a vehicular body has side sills disposed at lateral ends of the vehicular body. The rear structure further has side rear members having a hat-shaped cross-section and having a kick-up portion that is upwardly inclined. The side rear members are bonded to the side sills at bonded portions, and extend toward a rear of the vehicular body. The rear structure further has a cross member connecting side sills in a lateral direction across the vehicular body. The cross member is connected to each of the side sills at connected portions at a rear of the kick-up portions. The rear structure further has reinforcements having a closed cross-section in a longitudinal plane and in a lateral plane. The reinforcements are disposed in the side rear members between the bonded portions and the connected portions.

Description

technical field [0001] The present invention relates to a vehicle body rear structure having a rear side member extending from a side sill rear to the vehicle rear. Background technique [0002] Usually, at the rear of the car, there are a pair of left and right rear side members extending in the front and rear direction of the vehicle on both sides of the vehicle width direction. The front part of the rear side member is joined to the rear part inside the side sill. The part of the rear bumper is extended. [0003] In such a rear side member extending in the front-rear direction of the vehicle, it is known to provide a bulkhead (sheet mounting bracket) inside to increase the section strength, thereby preventing upward bending of the rear side member due to load input during a rear collision, However, since sufficient reinforcement cannot be obtained only by this bulkhead, a larger side sill reinforcement is provided (for example, refer to Patent Document 1). [0004] Pate...
