<p>PURPOSE:To improve startability of an engine, in a clutch device driven through a switching means provided to a change shift lever, by performing half clutch conditional operation at starting of the engine when said clutch device is operated through said switching means. CONSTITUTION:A clutch mechanism 10, interposed between an engine and speed changer, is formed releaseable when a clutch operating cylinder 20 is operated. simultaneously the first oil hydraulic cylinder 30, interlocking to a clutch pedal 40, and the second oil hydraulic cylinder 50 are connected to the cylinder 20. A gas pressure operating means 60 of air cylinder or the like is connected to the second oil hydraulic cylinder 50 and connected to a gas pressure generating source 100 through a valve mechanism 70 controlled by a switching means 80 interlocking to a change shift lever 90. Further the gas pressure operating means 60 is connected to a pressure reducing valve 110 controlled by a switching means 130 interlocking to an accelerator pedal 120.</p> |
