PURPOSE:To make the operating timing of a solenoid valve properly accordable with a half-clutch position even if there is some abrasion in a clutch plate, by installing a switch, which detects the half-clutch position, via an adjusting device changing an operating position according to an abrasion loss in the clutch plate. CONSTITUTION:A switch effector 35 which detects that a rocking position of a lever 28 in a clutch operating system is in a half-clutch position is installed via an adjusting device 20 changing an operating position according to an abrasion loss in a clutch plate of a clutch unit 30. In consequence, the operating position of the switch effector 35 is altered according to the abrasion loss of the clutch plate of the clutch unit 30, whereby the switch effector 35 is able to accurately detect the time when the rocking position of the lever 28 is in the half-clutch position. Therefore, even if abrasion occurs in the clutch plate, the operating timing of a solenoid valve 6 is properly accordable with the half- clutch timing, thus stable starting operation can be done on an uphill road.
