DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single wheel vehicle. The one-wheeled vehicle of the present invention includes a unicycle,
A vehicle in which two or more wheels are juxtaposed on the same axis and drive wheels contact the road surface at one point when viewed from the side of the vehicle, and a vehicle in which auxiliary wheels are provided before or after the drive wheels. In addition, the vehicle mainly includes a vehicle that travels substantially as a unicycle.

[0002]

2. Description of the Related Art A unicycle equipped with a vibration reducing device is disclosed in Japanese Unexamined Patent Publication No. 9-1.
No. 75462. In the unicycle described in this publication, a counter torque is applied by a gyro in a direction opposite to the direction in which the unicycle falls, so as to reduce the swing and enhance the self-sustaining stability.

[0003]

However, in the unicycle described in the above-mentioned publication, a large moment is required because a force is applied to return the inclination of the vehicle body to the neutral position by the gyro moment by the gyro flywheel.
The flywheel shape becomes large, and a compact body shape cannot be obtained.

Further, in order to stabilize the posture of the vehicle body, the vehicle body swings back and forth and right and left around the grounding point of the wheel, so that the rider's position is greatly shaken and the riding comfort is reduced. The posture always shakes and becomes unstable,
Pedaling is difficult.

The present invention has been made in consideration of the above prior art, and provides a unicycle in which the swing of the occupant when adjusting the posture of the vehicle body is reduced to stabilize the occupant's posture and improve the riding comfort. With the goal.
