Abstract:
1. A parallel axes type transmission comprising: an input shaft, an intermediate shaft, an idle shaft, and an output shaft extending in parallel to each other; a common gear fixed to said input shaft; a first intermediate gear idly rotatably provided on said intermediate shaft; a second intermediate gear fixed through a one-way clutch to said intermediate shaft; a third intermediate gear idly rotatably provided on said intermediate shaft; a fourth intermediate gear idly rotatably provided on said intermediate shaft; a first idle gear provided on said idle shaft and meshing with said common gear and said second intermediate gear; a second idle gear idly rotatably provided on said output shaft and meshing with said common gear and said first intermediate gear; a first output gear fixed to said output shaft and meshing with said third intermediate gear; a second output gear fixed to said output shaft and meshing with said fourth intermediate gear; a first clutch for making the connection and disconnection between said first intermediate gear and said intermediate shaft; a second clutch for making the connection and disconnection between said third intermediate gear and said intermediate shaft; and a third clutch for making the connection and disconnection between said fourth intermediate gear and said intermediate shaft, wherein a first idle drive route is formed by said common gear, said first idle gear, said second intermediate gear, and said one-way clutch, a second idle drive route is formed by said common gear, said second idle gear, said first intermediate gear, and said first clutch, and when said first clutch is engaged to connect said first intermediate gear to said intermediate shaft, slippage occurs in said one-way clutch to cut off the drive through said first idle drive route.
