<p>PROBLEM TO BE SOLVED: To dissolve the problem that the structure becomes complicated and expensive due to the constitution by plural members of a spring supporting means for supporting a return spring. SOLUTION: In a multiple disk clutch device for transmitting power by actuating a piston 3 slidably stored in a cylinder 2 formed on a drum 1a, by oil pressure supplied to an oil pressure chamber 2a in the cylinder 2, to crimp driving and driven plates by the piston 3; a canceling piston 6 is provided so as to face the piston 3 in the cylinder 2, a return spring 5 for returning the piston 3 to a former position is provided between the pistons 6 and 3, and a spring supporting means 7 for supporting the end part of the spring 5 is provided integrally with the piston 6 on the piston 6, to reduce the number of part items, thereby providing the device inexpensively.</p> |
