PURPOSE:To stabilize the operation of a hydraulic clutch and improve the efficiency thereof by forming three liquid passages which independently supply liquid into a liquid pressure chamber of each clutch piston and lubricating part, inside a clutch shaft in the axial direction thereof. CONSTITUTION:Three liquid passages 114, 116 and 118 which independently supply liquid into liquid pressure chambers 80 and 82 of clutch pistons 58 and 60 and a lubricating part is formed inside a clutch shaft 10 in the axial direction thereof. Since liquid pressure in a liquid pressure source can be supplied as working liquid presure for the clutch pistons 58 and 60, without being subjected to pressure loss caused by supply of lubricant, stable operation of a hydraulic clutch can be effected and the hydraulic operation having high efficiency be also effected. |
