An output frame is connected to a portion of a radially outer portion of a carrier, the portion being closer to a front plate than to a rear plate. The carrier has a first region as an external force transmission path between front pin support surfaces and the output frame, and a second region as the external for transmission path between rear shaft support surfaces and the output frame, and a stiffness with respect to a twist force of the first region and a stiffness with respect to the twist force of the second region are equal to each other. In the front plate and the rear plate, a stiffness with respect to a radial tensile force applied to the front pin support surfaces and a stiffness with respect to the radial tensile force applied to the rear shaft support surfaces are equal to each other.
