Abstract

An object is to provide a vehicle rear portion structure that improves rigidity of a vehicle rear portion. At a wheel house connecting member, both end portions in a vehicle transverse direction of a top surface portion are joined to joining stays that are provided at wheel houses, and lower portions of both end portions in the vehicle transverse direction of a vertical wall portion, that extends toward a vehicle lower side from the top surface portion, are joined to fixing members. Accordingly, vehicle rigidity between the wheel houses, that are connected by the wheel house connecting member at a rear portion of a vehicle, improves.

First claim

1 . A vehicle rear portion structure comprising:
wheel houses that are provided at both side portions in a vehicle transverse direction at a vehicle rear portion, and to which lower end portions of first quarter pillars, that extend in a vehicle vertical direction, are joined, and to which both side portions of a rear floor panel, that structures a vehicle floor portion, are joined; and a wheel house connecting member that connects the wheel houses, wherein the wheel house connecting member comprises: an upper side member that structures an upper portion side of the wheel house connecting member, and whose both end portions in the vehicle transverse direction are joined respectively to joining members that are joined to the wheel houses and the first quarter pillars; and a lower side member that extends toward a vehicle vertical direction lower side from the upper side member of the wheel house connecting member, and whose lower portions of both end portions in the vehicle transverse direction are joined respectively to fixing members that are joined to the wheel houses and the rear floor panel.

2 . The vehicle rear portion structure of claim 1 , wherein a deck board, that structures a floor surface of a luggage compartment, is supported by the upper side member of the wheel house connecting member.

3 . The vehicle rear portion structure of claim 1 , comprising:
second quarter pillars that are provided at vehicle rear sides of the first quarter pillars at the both side portions in the vehicle transverse direction of the vehicle rear portion, and that extend in the vehicle vertical direction; and pillar connecting members that are joined respectively to the second quarter pillars and joined regions of the first quarter pillars and the wheel houses, and that connect the second quarter pillars and the joined regions.

4 . The vehicle rear portion structure of claim 3 , wherein the pillar connecting members are disposed at acute angles with respect to the vehicle vertical direction as seen in a vehicle side view.

5 . The vehicle rear portion structure of claim 2 , comprising:
second quarter pillars that are provided at vehicle rear sides of the first quarter pillars at the both side portions in the vehicle transverse direction of the vehicle rear portion, and that extend in the vehicle vertical direction; and pillar connecting members that are joined respectively to the second quarter pillars and joined regions of the first quarter pillars and the wheel houses, and that connect the second quarter pillars and the joined regions.

6 . The vehicle rear portion structure of claim 5 , wherein the pillar connecting members are disposed at acute angles with respect to the vehicle vertical direction as seen in a vehicle side view.
