摘要： PURPOSE:To improve the rigidity of return springs by disposing uniformly continuously circumferentially the return spring to smooth the return of a piston by the return springs while forming circumferentially continuously a press part of the piston for pressing a frictional element. CONSTITUTION:A piston 44 is fitted inside the bottom 42a side of a second drum 42 provided with a reverse clutch 20. An annular press part 44a is provided to project from the outer periphery of the side face of the piston 44 opposed to the reverse clutch 20 to make the tip of the press part 44a abut sgainst the reverse clutch 20. A plurality of return springs 46 are disposed at equal intervals on the outer periphery of a reduced diameter part 44c formed of a vertical surface 44b on the outer periphery of the press part 44a. The return springs 46 are contractively provided between the vertical surface 44b and a snap ring 48 engaging the inner periphery of the second drum 42.
