The transmission includes a rotation shaft, a shift gear, and a gear switching part. The shift gear is rotatably supported by the rotation shaft. The gear switching part is relatively unrotatably supported by the rotation shaft in a movable manner in an axial direction. The gear switching part is configured to be moved in the axial direction by a shift fork, to switch connection and disconnection between the rotation shaft and the shift gear. The gear switching part and the shift fork have a bearing therebetween. The bearing is brought into contact with the gear switching part and the shift fork, thereby reducing friction between the gear switching part and the shift fork, resulting in improvement of durability of the sliding surfaces of the gear switching part and the shift fork.

A rotation detecting device has a junction body, and a rotation sensor. A rotor of the rotation sensor is spaced from a change drum in the axis direction, and is rotatable about the rotational axis. The rotating position of the rotor is detected by a detector of the rotation sensor. The junction body is separatable from the change drum and the rotation sensor, is rotatable about the rotational axis, and transmits the rotative movement of the change drum to the rotor.
