Abstract

A flange of a left rear side portion (aluminum member) includes a plane section extending toward a vertical wall of a left side member (steel plate-like member). The left side member includes a bent portion formed as a result of being bent between a flange and the vertical wall of the left side member, and a base section, which serves as a start point at which the bent section starts to be bent from the flange of the left side member. The plane section of the left rear side portion is provided such that it covers an area substantially up to the base section of the left side member.

First claim

We claim:

1. A vehicle structure comprising:
an iron member including a first vertical wall and a first flange disposed continuously from the first vertical wall via a first bent portion therebetween; and
an aluminum member disposed above the iron member and including a second vertical wall and a second flange disposed continuously from the second vertical wall, wherein the second flange of the aluminum member is disposed above the first flange of the iron member and joined to each other,
wherein the second flange includes a plane portion above the first flange, the plane portion extending toward the first vertical wall,
wherein the first bent portion includes a base point on the first flange side thereof, the base point being a point at which a bent shape of the first bent portion starts, and
wherein the plane portion of the second flange covers the iron member at least up to the base potion.

2. The vehicle structure according to claim 1 , wherein friction stir welding is performed on the aluminum member toward the iron member in a state in which a sealing member is interposed between the first flange and the second flange to provide a welded joint portion, and
wherein the following equation is satisfied:
S1>S2

wherein (S1) is a distance between an axis (T1) of the first vertical wall of the iron member and a vertical center line (C) of the welded joint portion, and (S2) is a distance between an axis (T2) of the second vertical wall of the aluminum member and the center line (C) of the welded joint portion.

3. The vehicle structure according to claim 1 , wherein the second flange of the aluminum member is disposed continuously from the second vertical wall via a second bent portion therebetween,
wherein the following equation is satisfied:
R1>R2

wherein R1 is a radius of curvature of an outer circumference of the first bent portion of the iron member, and R2 is a radius of curvature of an outer circumference of the second bent portion of the aluminum member.
