PURPOSE:To control a clutch lever with a remarkably light force, by applying positive or negative pressure generated in accordance with an engine output to cooperatively assist an operating mechanism of a clutch when the clutch is disengageably controlled by clutch lever. CONSTITUTION:To disconnect a clutch under an operational condition of an engine 2, if a clutch lever 4 is controlled, an opening and closing valve 27 of a pipe 24 is opened at a point of time, in which this clutch lever 4 is moved from a position A to B, to introduce lubricating oil from an oil pump 5 in the engine 2 as the working fluid to an oil chamber 23 in a clutch device 1. The working fluid is applied to a piston 20 to operate a push rod 15 so as to be moved to the left side as shown in the drawing, and this action cooperatively assists the control operation of the lever 4 manually moved further to a position C from the position B, in this way, the lever 4 can be very lightly controlled. |
