摘要： A first rotating element (E1) is a first sun gear (SG1) that rotates with a rotor (12). A third rotating element (E3) is a first ring gear (RG1) connected to a case (9). A fourth rotating element (E4) is a second ring gear (RG2) that rotates with an input element (Ei). A second rotating element (E2) is a first carrier (CR1) rotatably supporting a first pinion gear (PG1) and a second pinion gear (PG2) that rotate together. The first pinion gear (PG1) meshes with the first sun gear (SG1) and the first ring gear (RG1). The second pinion gear (PG2) has a smaller diameter than the first pinion gear (PG1) and meshes with the second ring gear (RG2). The first sun gear (SG1) is supported in a radial direction (R) with respect to the case (9) via a first support bearing (B1). The second ring gear (RG2) and the input element (Ei) are connected such that their relative movement in the radial direction (R) is restricted.
