摘要：Disclosed is a torque converter for a vehicle that comprises a lock-up clutch which can be applied to a multi-plate clutch and can stably fix a piston in a narrow space. The torque converter for a vehicle according to the present invention comprises: a front cover; an impeller that is coupled with the front cover and rotates; a turbine that is arranged at a position facing the impeller and rotates in response to the rotation of the impeller; a reactor that is positioned between the impeller and the turbine to change the flow of an oil from the turbine to the impeller side; the lock-up clutch that transmits a driving force from the front cover directly to a transmission; and a torsional damper that is coupled with the lock-up clutch and includes springs which are arranged in a circumferential direction of a shaft to absorb vibration and impacts in a rotational direction. A hub, which is coupled with an inner side of the front cover, has the same center of rotation as the front cover, has an outer circumferential surface formed of a spline, and is coupled with the front cover. A piston, which is provided in the lock-up clutch, is coupled with the hub. A movement restricting member, which restricts an axial direction movement of the piston, is coupled with the hub.
