A lock-up device for a torque converter transmits a torque from a front cover to an input shaft of a transmission. The lock-up device includes a clutch portion, a piston and hydraulic oil leading-out portion. The clutch portion is disposed between the front cover and a turbine, and includes at least one clutch plate. The piston is disposed to be axially movable and presses the at least one clutch plate toward the front cover so as to turn the clutch portion into a torque transmitting state. The hydraulic oil leading-out portion is mounted to a piston-side lateral surface of the front cover, and leads a hydraulic oil residing between the front cover and the piston to an oil discharge channel provided in the input shaft of the transmission by utilizing rotation of the front cover.
