Thereafter, the driver places his / her feet on the tread plate, and the driver continuously shakes his / her waist to the left and right, thereby forcibly swinging the rear wheel to the left and right. At this time, the front wheels are always operated in the traveling direction.

Next, the operation when the rear wheel is swung to the right will be described. The rear wheel receiver and the rear wheel which have swung to the right stop by a stopper in a state where they are directed obliquely to the front right. Since the person's right has inertia, he tries to push the rear wheel to the right. In this case, since the rear wheel is fixed in a state where the rear wheel faces diagonally to the right, the rightward force is changed to a force for pushing the rear wheel diagonally to the right. At this time, since the front wheels are oriented in the front traveling direction, the traveling direction of the motorcycle can meanly move in the front traveling direction while meandering. The center of gravity shifts to the right when shaken to the right, but the balance can be balanced by tilting the main body to the left or applying weight to the left side of the steering wheel. In addition, it is easier to drive if the rear wheel is swung to the right while the main body is tilted to the left.

Further, in the rear swing type two-wheeled vehicle according to the present invention (claim 2), a front wheel is disposed in front of a vehicle body and a rear wheel is disposed at a rear portion on a straight line thereof, and the front wheel is fixed to a lower portion of a steering wheel by an axle, The handle is attached to the front part of the main body, the iron plate is fixed horizontally to the rear part of the main body, the movable iron plate is horizontally fixed to this iron plate by the rotating shaft, the movable iron plate and the rear wheel receiver are fixed, and the rear wheel The receiving and rear wheels are fixed by an axle, a spring is mounted between the main body and the movable iron plate, and a tread is fixed to the upper part of the main body.

In this case, the rear wheel is stabilized in the forward direction by the spring force, so that the rear wheel does not swing easily even when stepping on a pebble or the like during traveling, and the vehicle is more easily driven.

In the rear swing type two-wheeled vehicle according to the present invention (claim 3), a front wheel is disposed in front of a vehicle body and a rear wheel is disposed at a straight rear portion thereof, and the front wheel is fixed to a lower portion of a steering wheel by an axle. The handle is attached to the front of the main body, the movable support is mounted to the rear of the main body so that it can move left and right, the rear wheel is fixed to the movable support with an axle, and the tread is fixed to the upper part of the main body .

In this case, the provision of the movable support simplifies the mounting structure of the rear wheel.
