ABSTRACT:
A lock-up device is used for a torque converter comprising a front cover connected to an input-side rotation member, an impeller fixed to the front cover, and a turbine provided opposite to the impeller and connected to an output-side member. This lock-up device comprises a plate member and a piston. The above described plate member is connected to the output-side member and located between the turbine and the inner wall of the front cover, and can be brought into contact with the inner wall of the front cover. The above described piston which is connected to the front cover so as not to be relatively rotatable is for pressing the plate member against the inner wall of the front cover.
