PROBLEM TO BE SOLVED: To reduce the number of components and simplify the structure of a lock-up device having a structure where three or more friction surfaces are provided by attaching the clutch member to a piston. SOLUTION: A lock-up device 7 comprises a piston 75, a clutch plate 71, and an annular connection member 76. The piston 75 comprises a pressurizing part 75d that faces a friction surface 11b of a front cover 11. The clutch plate 71 comprises a frictional connection part 71a which is attached to the piston 75 to allow movement in axial direction but not to allow relative rotation and arranged between the friction surface 11b and the pressurizing part 75d in axial direction. The connection member 76 comprises a body 76a which is fixed to the front cover 11 and flexible in axial direction, and a press-fitting part 76b so provided at the end of the body 76a in radial direction as to be arranged between the frictional connection part 71a and the pressurizing part 75d in axial direction.
