## Abstract

A vehicle includes a motor configured to drive a vehicle wheel, a battery configured to supply electric power to the motor, and a radiator configured to exchange heat between a coolant for cooling the motor and outside air. The radiator is disposed below a floor surface of the vehicle and in a gap between the motor and the battery in a front-rear direction of the vehicle.

## Claims

### Claim 1

A vehicle comprising:
a motor configured to drive a vehicle wheel;
a battery configured to supply electric power to the motor; and
a radiator configured to exchange heat between a coolant for cooling the motor and outside air,
wherein the radiator is disposed below a floor surface of the vehicle and in a gap between the motor and the battery in a front-rear direction of the vehicle in a state of being inclined downward from the front to the rear of the vehicle, and is covered with an undercover from below, and
wherein the undercover includes an opening portion for supplying the outside air to the radiator in front of the radiator with respect to the vehicle.

### Claim 2 (depends on 1)

The vehicle according to claim 1,
wherein the undercover includes an inclined surface which is behind the opening portion and below the radiator and which faces the opening portion and is inclined upward from the front to the rear of the vehicle.

### Claim 3 (depends on 1)

The vehicle according to claim 1,
wherein the radiator is disposed in a space that is surrounded by a frame member supporting the motor, a cross member, the battery, and the undercover.
