Conventionally, a cam face structure portion provided with a neutral positi on detecting cam is provided on the outer circumferential surface of a shift dr um and a neutral position detector is provided on a crankcase. Therefore, the main body of the detector protrudes externally from the crankcase, which poses a problem with space saving or the like. A contact member adapted to detect a neutral position and a reverse position of a shift drum is integral ly attached to a shift drum skip-turn-prevention plate secured to an end of the shift drum, and a neutral position detecting switch and a reverse position detecting switch are integrally mounted to a crankcase or a crankcase cover, the detecting switches being energized upon contact with the contact member. |
