<p><P>PROBLEM TO BE SOLVED: To provide a bonded piston seal causing no shift shock when a pressing part provided at a piston member abuts on or presses/engages a multiple disc clutch. <P>SOLUTION: The bonded piston seal 1 comprises the piston member 10 disposed in a cylinder 70 of bottomed cylinder shape to partition a pressure chamber M between itself and the cylinder 70, and the pressing part 40 pressing the multiple disc clutch 80 located on the axially opposite side to the pressure chamber M through the piston member 10. The pressing part 40 is composed of a turn-around part 41 connected to an outer peripheral cylinder part 13 of the piston member 10, and a columnar part 50 formed of a rubber elastic body stuck to the turn-around part 41 so that a tip part 51 abutting on the multiple disc clutch 80 axially projects onto the multiple disc clutch side B rather than a bent part 44 of the turn-around part 41 to have a radial space part 56 between itself and the turn-around part 41. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
