## Abstract

Each of a monocoque body and a subframe is integrally formed of reinforced resin. The subframe has a bottom portion and an upstanding portion. The bottom portion is fixed to the lower portion of the rear wall of the monocoque body and extends rearward of the vehicle. The upstanding portion extends upward from the bottom portion. An engine is directly mounted on the rear surface of the upstanding portion.

## Claims

### Claim 1

A monocoque vehicle comprising:
a monocoque body integrally formed of reinforced resin;
a subframe integrally formed of reinforced resin, the subframe including a bottom portion and an upstanding portion extending upward from the bottom portion, the bottom portion being fixed to a lower portion of a rear wall of the monocoque body, the bottom portion extending rearward of a vehicle; and
an engine directly mounted on a rear surface of the upstanding portion of the subframe.

### Claim 2 (depends on 1)

The monocoque vehicle structure according to claim 1, wherein
the rear wall of the monocoque body has a projecting portion attached to an upper portion of the rear wall, the projecting portion extending rearward, and
an upper portion of the upstanding portion is fixed to the projecting portion.

### Claim 3 (depends on 1)

The monocoque vehicle structure according to claim 1, wherein
the reinforced resin that forms the subframe is a thermal resistant resin that is resistant at a higher temperature than a temperature at which the reinforced resin that forms the monocoque body is resistant.
