Abstract
Official abstract text for this publication.
Falling-in deformation, in which a second quarter pillar deforms so as to fall toward a vehicle vertical direction lower side, is suppressed. Due to twisting input being applied to a vehicle, a second quarter pillar deforms so as to fall toward the vehicle vertical direction lower side. A connecting member, whose lower end portion is joined to a joined region of a wheel house and a lower end portion of a first quarter pillar, receives this falling-in deformation of the second quarter pillar. Accordingly, because the connecting member, whose lower end portion is securely fixed, receives the falling-in deformation of the second quarter pillar, the falling-in deformation of the second quarter pillar is effectively suppressed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle rear portion structure comprising: a first quarter pillar that extends in a vehicle vertical direction at a vehicle rear side of a vehicle side portion, and whose lower end portion is joined to a wheel house; a second quarter pillar that is provided at a vehicle rear side of the first quarter pillar and extends in the vehicle vertical direction; and a connecting member that is a separate member from the first quarter pillar, the connecting member being directly joined to the second quarter pillar and to a joined region of the first quarter pillar and the wheel house, and connecting the second quarter pillar and the joined region. 2. The vehicle rear portion structure of claim 1 , wherein the connecting member is disposed at an acute angle with respect to the vehicle vertical direction as seen in a vehicle side view. 3. The vehicle rear portion structure of claim 1 , wherein cross-sectional shape of the connecting member orthogonal to the length direction is a hat shape that opens toward the vehicle transverse direction inner side, an upper end portion of the connecting member is joined to a curved portion at the second quarter pillar, and a lower end portion of the connecting member is joined to a joined region of the wheel house and the lower end portion of the first quarter pillar. 4. The vehicle rear portion structure of claim 1 , further comprising a second connecting member, wherein cross-sectional shape of the second connecting member orthogonal to the length direction is a hat shape that opens toward the vehicle transverse direction inner side, an upper end portion of the second connecting member is joined to a curved portion at the second quarter pillar, and a lower end portion of the second connecting member is joined to a joined region of the wheel house and the lower end portion of the first quarter pillar.
