<p>PROBLEM TO BE SOLVED: To make a stroke value itself reducible by reducing the extent of variations in an engaging stroke value due to parts manufacturing errors, in this static cylinder type clutch system. SOLUTION: This clutch system is equipped with a hub and a drum 54, a frictional engaging element 50 connected free of rotational power transmission to these elements, a pressing member 33 and a reaction member 56 installed at both ends in the axial direction as holding it between, and a hydraulic servo 3 operating detachment of this frictional engaging element 50, respectively. This hydraulic servo 3 is installed in a hold-down member 10, and thereby servo force is transmitted to the frictional engaging element 50 via the pressing member 33, and any reaction to be produced by the engagement is supported by the hold-down member 10 via the reaction member 56. Subsequently, a return spring 58 pushing back a piston 31 of the hydraulic servo 3 is installed in space between the pressing member 33 and the reaction member 56, making it so as to be pushed back via the pressing member 33, and then such a regulating means 59 as limiting the return value to the specified value is installed there.</p> |
