PURPOSE: To prevent a reverse rotation output to a driven part by connecting a driven shaft to a driven gear through a forward rotation locking one-way clutch, also journalling the driven shaft to a casing through a reverse rotation locking one-way clutch. CONSTITUTION: When a vehicle is forwardly advanced, by forwardly rotating a transmission, a driven shaft 102 and a driven gear 104 are integrally connected by a forward rotation locking one-way clutch 2. On the other hand, forwardly rotating the driven shaft 102 is permitted by a reverse rotation locking one-way clutch 3, to output transmission forward rotation to a driven part. When the vehicle is reversed, by reversely rotating the transmission, connecting the driven shaft 102 and the driven gear 104 is released by a forward rotation locking one-way clutch 2, to permit racing the driven gear 104. On the other hand, the driven shaft 102 is connected to a journalling part 107a of a casing 107 by the reverse rotation locking one-way clutch 3, to prevent reverse rotation of the driven shaft 102 by inertia, and outputting of transmission reverse rotation to the driven part can be prevented. |
