A lockup device 4 of a torque converter 1 is provided with a damper mechanism 44, which is axially movable together with a piston. Particularly, the lockup device 4 of a torque converter 1 is provided with a simplified structure that reduces production costs. The lockup device of a torque converter basically includes a clutch coupling portion and a damper mechanism 44. The damper mechanism 44 has a plurality of first claw portions 61, a drive member 50, a driven member 51, a plurality of torsion springs 52 and a first piston 43. The first claw portions 61 are fixedly coupled to the turbine 11. The driven member 51 has a plurality of second claw portions 59 that are axially movably and non-rotatably engaged with the first claw portions 61. The drive member 50 radially positions the driven member 51.
