Beschreibung
Zusammenfassung:	A supporting structure for wheel includes a wheel rotating as grounding and supporting a vehicle body, and a rotary body rotatable only in the opposite direction to a rotating direction of the wheel in association with proceeding of the vehicle body. A rotation axis of the wheel is arranged in substantially parallel to a rotation axis of the rotary body, and the rotation axis of the rotary body is arranged at a rear of and above the rotation axis of the wheel with respect to the proceeding direction of the vehicle body. The rotation axis of the wheel is movable between a reference position at which the rotation axis of the wheel moves forward with respect to the proceeding direction of the vehicle body so as to separate a circumferential surface of the wheel and a circumferential surface of the rotary body from each other and a contact position at which the circumferential surface of the wheel and the circumferential surface of the rotary body come in contact with each other, and also movable along an arc shaped track around the rotation axis of the rotary body as a center while rendering the circumferential surface of the wheel and the circumferential surface of the rotary body contact to each other.
