Rotation of a rotor (7) is transmitted via an input shaft (8) to a sun gear (11) of a gear set (5), and then a stepped planetary pinion (13) makes a planetary motion so that a small diameter gear (13b) rolls along a ring gear (12). The planetary motion is transmitted via a carrier (14 (14a, 14b)) and an output shaft (9) to a wheel hub (24). A motor-side coupler (25) is set such that the output shaft (9) is drivingly coupled to the carrier (14a) in a relatively displaceable manner, and a wheel hub-side coupler (26) is set such that the output shaft (9) is drivingly coupled to the wheel hub (24) in a relatively displaceable manner. A center of swinging displacement (O1) provided by a bearing (23) for the wheel hub (24) is configured to be located between a center of swinging relative displacement (02) provided by the coupler (25) for the carrier (14a) and the output shaft (9) and a center of swinging relative displacement (03) provided by the wheel hub-side coupler (26) for the output shaft (9) and the wheel hub (24).
