Abstract: 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.
