摘要： A lock-up clutch mechanism (7) includes a piston member (44), a drive member (52), a driven member (53), and a torsion spring (54). The piston member (44) is arranged between the front cover (14) and the turbine (19), such that the piston member (44) moves freely in an axial direction for engaging with and disengaging from the front cover (14). The drive member (52) includes a pair of plate elements (56) and (57), to which torque is inputted from the piston member (44). The plate elements (56) and (57) are axially arranged side by side and are fixedly couple to each other and define a spring receiving section. The driven member (53) extends between the plate elements (56) and (57) and has a window hole (58) corresponding to the spring receiving section. The torsion spring (54) is retained within the window hole (58) and is supported by the spring receiving section. The torsion spring (54) elastically couples the plate elements (56) and (57) and the driven member (53) in a rotational direction. The plate elements (56) and (57) are manufactured by a drawing process in which the plate elements (56) and (57) are drawn to different draw depths respectively. A thickness of one of the plate elements having a longer draw depth is smaller than a thickness of the other of the plate elements having a shorter draw depth.

摘要： A lockup unit for a torque converter is provided with a front cover coupled to an input member and a turbine coupled to an output member. The lockup unit includes: a disc-like piston disposed movably between the front cover and the turbine and pressingly contactable against the front cover; a flexible coupling mechanism for coupling the disc-like piston and the turbine in a circumferential direction; and a frictional resistance generating mechanism including a stationary member fixed to the disc-like piston and a flexible member which is brought into pressing contact with the stationary member so as to be rotatable together with the turbine, for generating a frictional resistance when the piston and the turbine are rotated relative to each other, to thereby reduce the number of the necessary mechanical components.
