PROBLEM TO BE SOLVED: To simplify a mechanism for connecting a piston to a front cover in a lockup device having the piston pressing the frictional connection section of a drive plate to the front cover. SOLUTION: The drive plate 72 of the lockup device 7 has the frictional connection section near the frictional face of the front cover and outputs torque to a plurality of springs 73. The piston 74 is coupled with the front cover relatively unrotatably and movably in the axial direction by oil pressure, and it is a member for pressing the frictional connection section to the frictional face. A piston connecting mechanism 75 allows the piston 74 to be coupled with the front cover relatively nonrotatably and to move in the axial direction, and it has a wire ring 80 capable of transmitting torque between the piston 74 and the front cover.
