PURPOSE:To make a differential gear mechanism utilizable as a transmission mechanism, by installing a dog clutch in a differential mechanism in addition, while controlling a coupled state between gears with the clutch. CONSTITUTION:A planetary gear mechanism 15 is installed in position around a shaft 5 inside a housing 1. At plural spots in a circumferential direction of the planetary gear mechanism 15, a pin 19 being projected rearward is locked, while a planetary gear 20 is supported around this pin 19 via a bush 21. An internal gear 25 with which the gear 20 engages is provided with an annular part 26 as one body, and a cylindrical part 27 is supported by an inner circumferential boss via a bearing 28. On the other hand, a dog clutch 30 is installed in and around the cylindrical part 27, and an input part 31 and output parts 32 and 33 of the dog clutch 30 all are formed with annular members and they are set up with longitudinal positional relations, holding the bush in between. |
