<p>At least one pair of first pockets (12A, 12D) are formed in the inner peripheral surface of a housing (1). The first pockets (12A, 12D) are arranged away from each other in a circumferential direction of the housing (1). Planetary gears (3A, 3B) meshed with one pair of side gears (2A, 2B) are rotatably received in the first pockets (12A, 12D), respectively. Second pockets 12B, 12C are formed in the inner peripheral surface of the housing (1) between the first pockets (12A, 12D). Transfer gears (4A, 4B) are rotatably received respectively in the second pockets (12B, 12C). The transfer gears (4A, 4B) are in meshing engagement with the planetary gears (3A, 3B) respectively, and also in meshing engagement with each other. <IMAGE></p> |
