<p>A transmission for a vehicle having a sub shaft supported in casings via bearings, and an input gear, an output gear, and a boss of a clutch outer, etc. stacked on the sub shaft and retained by a cotter key. The input gear and the output gear are helical gears, and thrust forces acting on the two gears are generated in opposite directions. A rightward thrust force acting on the input gear is borne by the casing via an annular projection, t he sub shaft and the bearing, and a leftward force acting on the output gear, which is separated from the cotter key by a gap, is borne by the casing via the bearing provided on the side face o f the output gear. This arrangement eliminates any need for fixing gears supported on a shaft o f a transmission by a nut or a bolt in the axial direction, thus saving space and reducing th e number of parts.</p> |
