Abstract
A lock-up device for a torque converter is configured to transmit a torque from a front cover to a transmission-side member through a turbine. The lock-up device includes a clutch portion, a piston and an elastic member. The clutch portion is disposed between the front cover and the turbine, and includes a clutch plate. The piston is movable in an axial direction. The piston includes a pressing surface for pressing the clutch plate. The piston turns the clutch portion into a torque transmission state. The elastic member is disposed on a same side as the pressing surface of the piston. The elastic member is begins to elastically deform before the pressing surface contacts the clutch plate in conjunction with movement of the piston toward the clutch portion.
