## Abstract

There is provided a vehicle body structure including an upper section that is integrally casted using a non-ferrous metal material, that includes a transmission section to which an external force is transmitted and a join section extending out from the transmission section, a connection section that is formed using a steel material, and that is joined to the join section by riveting, and a member section that is formed using a steel material, and that is joined to the connection section by welding.

## Claims

### Claim 1

A vehicle body structure comprising:
an upper section that is integrally casted using a non-ferrous metal material, that includes a transmission section to which an external force is transmitted and a join section extending out from the transmission section;
a connection section that is formed using a steel material, and that is joined to the join section by riveting; and
a member section that is formed using a steel material, and that is joined to the connection section by welding,
wherein a second moment of area with respect to a vehicle front-rear direction axis of a cross-section of the join section, taken along the vehicle front-rear direction and the vehicle up-down direction, decreases on progression toward the vehicle width direction inside.

### Claim 2 (depends on 1)

The vehicle body structure of claim 1, wherein:
the upper section is a pair of suspension tower upper sections disposed at the left and right in the vehicle width direction; and
the member section is a cross-member connecting the pair of suspension tower upper sections through the connection section.
