To provide a vehicle which can provide a sense of stability in low-speed traveling or stopping and can provide a sense of steering like a two-wheeler at high-speed traveling even when it is inclined.

The vehicle 1a includes: a lateral pair of front wheels 11 and 12 provided on at least one side of the front side and rear side in an advancing direction; a rolling mechanism 30 which interlocks inclinations of the front wheels 11 and 12; and a tread control mechanism 40 which controls the distance between the wheels 11 and 12 due to the speed. In the vehicle 1, a rolling traveling similar or close to a two-wheeler can be enjoyed in high-speed traveling by reducing the distance between the front wheels 11 and 12, and the sense of stability of a three-wheeler can be obtained in stopping by extending the distance between the front wheels 11 and 12.
