Patent ID: 8157036

Claim:
An in-wheel motor, comprising: an electric motor generating motive power; a speed reducer arranged between a wheel and said electric motor to reduce an output of said electric motor; a motive power transmission mechanism; a rotation shaft having a portion, the rotation shaft arranged toward said wheel relative to said speed reducer to transmit an output of said speed reducer to said wheel and said portion connecting said rotation shaft and said motive power transmission mechanism; and a rotary support member that rotatably supports said rotation shaft, wherein said electric motor is supported by a dynamic mass damper mechanism and the dynamic mass damper mechanism is supported by suspension arms that connect the dynamic mass damper to a vehicle body, said rotation shaft is connected to said motive power transmission mechanism transmitting said motive power to said wheel and supports said electric motor allowing said electric motor to pivot around the portion, at least one of said suspension arms connect said rotary support member with said vehicle body, said electric motor is attached to said rotary support member via said dynamic mass damper mechanism, and the rotation shaft and the dynamic mass damper mechanism transmit all functional loads or forces between the electric motor and other components of the in-wheel motor.
