The driven plate (20) is connected to a turbine (5.) The torsion spring (21) connects the piston (17) and the driven plate (20) elastically in a circular direction. The retaining plate (19) is divided into at least two parts in a circular direction and regulate the movement of the torsion spring (21) outward in a radial direction while fixed to the piston (17) or the driven plate (20). An end part of the face of the divided part of the retaining plate (19) to regulate the torsion spring (21) is chamfered.
