According to the above configuration, due to the design of the vehicle, the strength of the lower side portion of the rear window opening, which is relatively thin and receives the load from the rear suspension, is sufficiently reinforced by the above-described rear pillar reinforcement. Thus, the strength of the portion can be improved.

In one embodiment of the present invention, a rear end of the rear pillar reinforcement is connected to a rear package member arranged in a vehicle width direction at a lower side of the rear window opening.

According to the above construction, since the rear end of the rear pillar reinforcement is connected to the rear package member, the rear package member and the left and right rear pillars extending in the vehicle width direction along the lower side of the opening in which the rear window is provided. It can be reinforced continuously with reinforcement,
As a result, it is possible to improve the strength of the entire vehicle body and the strength of the lower front corner of the rear window where stress is concentrated.

In one embodiment of the present invention, the door opening is provided with a front door which is supported at the front side of the door opening via a hinge so as to be openable and closable. According to the above configuration, the above-mentioned effect is particularly effective in the case where such a front door is provided, and since the hinge attachment portion has the annular reinforcement, the support rigidity of the front door can be improved. it can.

In one embodiment of the present invention, the door opening is provided with a rear door which is openably and closably supported at the rear side of the door opening via a hinge.
According to the above configuration, the above-described effect is particularly effective in the case where such a rear door is provided, and the support rigidity of the rear door can be enhanced because the annular mounting portion has the annular reinforcement.

In one embodiment of the present invention, the rear end of the front door is locked to the front end of the rear door, and the front end of the rear door is connected to at least one of the upper side and the lower side of the door opening. It is locked. According to the above configuration, since the door is locked at the high rigidity portion of the door opening where the annular reinforcement is present, it is possible to improve the support rigidity when the door is closed.
