<p>Object
In a transmission system for vehicles in which shift position changing drive means is coaxially connected to a shift drum (101) selectively establishing a plurality of gear trains (G1,G2,G3,G4,G5,G6) for respective gear steps capable of selective establishment in response to a turned position and a shift position sensor (118) detects which one of the gear trains (G1,G2,G3,G4,G5,G6) is being established, the number of component parts is reduced and assembly performance is enhanced while allowing for automatic gear shifting by use of a shift actuator (119). Solving Means
A shift actuator (119) exerting power driving shift position changing drive means (110) and a shift position sensor (118) are mounted to a cover member (120) attached to and covering a crankcase (119).</p> |
