In one embodiment of the present invention, the gusset member includes a third gusset in addition to the first gusset and the second gusset, and the third gusset is disposed on the indoor side of the second gusset. It is fixed to one gusset.

According to the above structure, since the gusset member is composed of the above-mentioned first, second and third gussets in total, the support strength of the rear suspension is further improved.
In addition, the rigidity of the vehicle body around the rear suspension can be further improved.

In one embodiment of the present invention, the third gusset and the upper portion of the rear suspension are fastened together,
The first part is offset from the fastening part to the front and rear,
The second and third gussets are fastened together.

According to the above construction, the upper portion of the rear suspension can be fastened to the third gusset, and the portion offset forward and backward from the fastening portion of the third gusset can be fastened to the first and second gussets. Therefore, it is possible to further improve the support rigidity of the rear suspension and the rigidity of the vehicle body around the rear suspension while ensuring a good assembling property.

In one embodiment of the present invention, an anchor reinforcement for partitioning a closed cross section is provided in the package member to which the second gusset is connected.

According to the above structure, since the anchor reinforcement for partitioning the closed cross section is provided inside the package member, the rigidity of the package member can be further improved, and the child reinforcement can be performed in correspondence with the anchor reinforcement. Internal parts such as anchors can also be attached.

In one embodiment of the present invention, the suspension housing reinforcement is connected to the rear pillar inner. According to the above configuration, the rigidity of the entire rear vehicle body can be improved by the connection structure between the suspension housing reinforcement and the rear pillar inner.
