A reducer (13) includes a fixed housing (14), a rotation housing (15), and multi-stage planetary gear mechanisms (21, 31, 41). The fixed housing contains a motor (2) 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 (41) located at a downstream position in a direction in which motive power is transmitted. The final-stage planetary gear mechanism (41) include a planetary gear (44) rotatably supported by a planetary gear shaft (45) that is supported at one end of the planetary gear shaft by the one-end wall (14a) of the fixed housing (14).Fig. 1
