摘要： A carrier (CR) rotatably supports a first pinion gear (PG1) and a second pinion gear (PG2) that rotate integrally with each other. One of the carrier (CR) and a ring gear (RG) is connected to a first gear (32) so as to rotate integrally with the first gear (32). A second gear (33) meshes with the first gear (32). The first gear (32) and the second gear (33) are each a double helical gear having a pair of tooth portions with mutually opposite helix directions. The first pinion gear (PG1) and the second pinion gear (PG2) are each a helical gear. The helix directions of the tooth portions of the first pinion gear (PG1) and the second pinion gear (PG2) are set such that the thrust load that the first pinion gear (PG1) receives from a sun gear (SG) and the thrust load that the second pinion gear (PG2) receives from the ring gear (RG) are opposite to each other.

摘要： A second gear (33) meshes with a first gear (32) and is connected to an output member (2) so as to rotate integrally with each other. A rotor (12), a planetary gear mechanism (31), and the first gear (32) are disposed on a first axis (X1) in a described order from an axial first side (L1) toward an axial second side (L2). A connecting member (6), a differential gear mechanism (4), and the second gear (33) are disposed on a second axis (X2) parallel to the first axis (X1) in a described order from the axial first side (L1) toward the axial second side (L2). The planetary gear mechanism (31) has a smaller diameter than a rotating electric machine (1) and a larger diameter than the first gear (32). The differential gear mechanism (4) has a smaller diameter than the second gear (33) and larger diameter than the connecting member (6).
