Abstract
A reducer includes a fixed housing, a rotation housing, and multi-stage planetary gear mechanisms. The fixed housing contains a motor in the fixed housing. The rotation housing is rotatably supported by the fixed housing via a bearing at an outer surface of a one-end wall of the fixed housing. The multi-stage planetary gear mechanisms are configured to decelerate a rotation of the motor and transmit the rotation that has been decelerated to the rotation housing. The multi-stage planetary gear mechanisms include a final-stage planetary gear mechanism located at a downstream position in a direction in which motive power is transmitted. The final-stage planetary gear mechanism include a planetary gear rotatably supported by a planetary gear shaft that is supported at one end of the planetary gear shaft by the one-end wall of the fixed housing.
