## Abstract

This vehicle subframe (15) includes a main body section (32) that results from a top section (41) and a bottom section (42) being provided with a predetermined gap in the vertical direction by means of being formed in a hollow shape by means of a core unit (80). A central joining section (38) is provided to the front-half section (32g) at the center (32h) in the vehicle widthwise direction of the main body section (32). Furthermore, in the main body section (32), a rear partition wall (64) is joined to the top section (41) and the bottom section (42) at the rearwards direction of the vehicle with respect to the central joining section (38). The rear partition wall (64) extends in the front-back direction of the vehicle.

## Claims

### Claim 1

A vehicular subframe integrally formed by casting using a core, the subframe comprising:
a body portion having a top part and a bottom part, the body portion having a hollow space formed by the core to vertically space the top part and the bottom part from each other with a predetermined interval therebetween;
left and right suspension support portions, the body portion having left and right end portions, the left and right suspension support portions being provided at the left and right end portions of the body portion, the suspension support portions being connected to suspension arms supporting suspensions; and
a connecting portion provided at the body portion, the connecting portion being connected to a connecting member supporting a power plant used as a power source of a vehicle,
wherein the body portion has a front part in a front-rear direction of the vehicle, and the connecting portion is provided at the front part of the body portion, and
wherein the body portion includes a partition wall provided rearwardly of the connecting portion, the partition wall extending in the front-rear direction of the vehicle, the partition wall being connected to the top part and the bottom part.

### Claim 2 (depends on 1)

The device of claim 1, wherein the body portion includes a widthwise center located at a center of a width of the vehicle, and the partition wall is provided at the widthwise center of the body portion.
