## Abstract

A vehicle includes an outside-air intake and an air inflow adjustment mechanism. The outside-air intake is configured to take outside air into an internal chamber of the vehicle. The air inflow adjustment mechanism is configured to adjust a flow rate of air that is to flow into the outside-air intake. The air inflow adjustment mechanism is disposed at the outside-air intake and includes one or both of a positive pressure source configured to perform discharge of gas and a negative pressure source configured to perform suction of gas.

## Claims

### Claim 1

A vehicle comprising:
an outside-air intake configured to take outside air into an internal chamber of the vehicle; and
an air inflow adjustment mechanism configured to adjust a flow rate of air that is to flow into the outside-air intake, the air inflow adjustment mechanism being disposed at the outside-air intake and comprising one or both of a positive pressure source configured to perform discharge of gas and a negative pressure source configured to perform suction of gas.

### Claim 2 (depends on 1)

The vehicle according to claim 1,
wherein the air inflow adjustment mechanism has first gas passage holes that are disposed in a lower wall surface of a front grille provided with the outside-air intake, and
wherein one or both of the positive pressure source and the negative pressure source are coupled to the first gas passage holes.

### Claim 3 (depends on 1)

The vehicle according to claim 1,
wherein the air inflow adjustment mechanism has second gas passage holes that are disposed in an upper wall surface of a front grille provided with the outside-air intake, and
wherein one or both of the positive pressure source and the negative pressure source are coupled to the second gas passage holes.

### Claim 4 (depends on 1)

The vehicle according to claim 1,
wherein the air inflow adjustment mechanism has third gas passage holes that are disposed in a side wall surface of a front grille provided with the outside-air intake, and
wherein one or both of the positive pressure source and the negative pressure source are coupled to the third gas passage holes.

### Claim 5 (depends on 1)

The vehicle according to claim 1,
wherein the air inflow adjustment mechanism has grille holes that are formed in a surface of a front grille provided with the outside-air intake, and
wherein one or both of the positive pressure source and the negative pressure source are coupled to the grille holes.
