Abstract
A first rotating element is a first sun gear that rotates with a rotor. A third rotating element is a first ring gear connected to a case. A fourth rotating element is a second ring gear that rotates with an input element. A second rotating element is a first carrier rotatably supporting a first pinion gear and a second pinion gear that rotate together. The first pinion gear meshes with the first sun gear and the first ring gear. The second pinion gear has a smaller diameter than the first pinion gear and meshes with the second ring gear. The first sun gear is supported in a radial direction with respect to the case via a first support bearing. The second ring gear and the input element are connected such that their relative movement in the radial direction is restricted.
