<p><P>PROBLEM TO BE SOLVED: To inexpensively provide a clutch piston for providing large operation force to a multiple disc clutch, by enlarging an outer diameter of a pressure receiving surface of the clutch piston more than a clutch pressing part. <P>SOLUTION: This clutch piston 1 has a piston body 10 movably inserted in the shaft direction into a cylinder 2, an inner peripheral seal lip 21 and an outer peripheral seal lip 22 slidably brought into close contact with an inner cylinder part 2a and an outer cylinder part 2b integrally arranged on the inner periphery and the outer periphery of this piston body 10. The piston body 10 has the clutch pressing part 16 for pressing the multiple disc clutch 4. This clutch pressing part 16 is bent and formed to the inner peripheral side via a tapered part 15 slantingly extending to the inner peripheral side from an outer cylindrical cylinder part 14 of the piston body 10. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
