Transmission for Vehicles

摘要

The invention relates to a transmission for a vehicle, comprising: a plurality of gear trains for respective speed steps accommodated in an engine case (11) to enable selective establishment; a shift drum (52) turnably carried by the engine case (11) so as to selectively establish the gear trains in response to a turning position; and shifting position changing drive means (62) covering one end of the shift drum (52) so as to drivingly turn the shift drum (52) in response to shifting operation. The transmission further comprises a shifting position sensor (102) for detecting which one of the gear trains is being established; wherein a to-be-detected member (96) connected to one end of the shift drum (52) so as to be rotatable with the shift drum (52) but to be incapable of relative rotation is turnably passed through an opening portion (99) provided in the shifting position changing drive means (62) and extends to a side opposite to the shift drum (52); and the shifting position sensor (102) for detecting a turning operation amount of the to-be-detected member (96) is secured to a cover member mounted to the engine case (11) so as to cover an external end of the to-be-detected member (96).
