## Abstract

A vehicle includes a battery, a duct through which air for cooling the battery flows, and a bumper, wherein an opening portion at an end of the duct faces an outer face of the duct inside the bumper.

## Claims

### Claim at position 1

1-10. (canceled)

### Claim 10 (depends on 19)

The vehicle according to claim 19, wherein the battery is located on a lower face of a floor panel of the vehicle.

### Claim 11

A vehicle in which a motor for running the vehicle is driven by a power stored in a battery, comprising:
equipment mounted on the vehicle; and
a duct through which a heat exchange medium exchanging heat with the equipment mounted on the vehicle flows,
wherein an opening portion at an end of the duct faces an outer face of the duct.

### Claim 12 (depends on 11)

The vehicle according to claim 11, further comprising a bumper of the vehicle,
Wherein the opening portion at the end of the duct faces the outer face of the duct inside the bumper.

### Claim 13 (depends on 12)

The vehicle according to claim 12, wherein the opening portion faces the outer face of the duct in a width direction of the vehicle.

### Claim 14 (depends on 12)

The vehicle according to claim 12, wherein the bumper has a guiding opening in a bottom face for guiding the duct into the bumper, and
a spacing is formed between the guiding opening portion and the duct.

### Claim 15 (depends on 12)

The vehicle according to claim 12 wherein the duct is an exhaust duct for exhausting the heat exchange medium after the heat exchange with the equipment mounted on the vehicle, and
the bumper is located at a back end portion of the vehicle.

### Claim 16 (depends on 15)

The vehicle according to claim 15, wherein the duct includes a duct end portion having the opening portion, and the duct end portion includes a hook-shaped portion.

### Claim 17 (depends on 16)

The vehicle according to claim 16, wherein the duct end portion includes a first bend portion and a second bend portion located downstream of the first bend portion in an exhaust direction,
the first bend portion is bent in a direction away from the opening portion in an opening direction of the opening portion, and
the second bend portion is bent in a direction opposite to the bend direction of the first bend portion.

### Claim 18 (depends on 11)

The vehicle according claim 11, wherein the opening portion is provided at a level higher than an allowing position of the vehicle to which submergence in water is allowed.

### Claim 19 (depends on 11)

The vehicle according to claim 11 wherein the equipment mounted on the vehicle is a battery.
