Patent ID: 7789178

Claim:
A wheel support device supporting a motor generating motive power, a wheel , and a motive power transmitting mechanism connected to an output shaft of said motor and transmitting said motive power to said wheel, comprising: a resilient member fitted to said motor and damping vibration of said wheel and said motor by extending and retracting; a rotary support member attached to said resilient member and rotatably supporting said wheel; a vibrating member vibrating together with said motor by a force received from a road surface when a vehicle runs; a restricting member restricting the vibration of said motor by coming into contact with said vibrating member at a prescribed region; a vibration damping mechanism connected to said vibrating member and said rotary support member and damping vibration of said resilient member to restrict extension and retraction of said resilient member; and a cushioning member provided at a portion of one of said vibrating member and said restricting member corresponding to said prescribed region brought into contact with the other, wherein said cushioning member corresponds to rubber members provided at said vibration damping mechanism, one on the side of said vibrating member and one on the side of said restricting member, spaced apart from each other.
