ー形状。 The input side front cover has a disc-shaped end wall and a cylindrical outer peripheral wall integrally formed with the outer peripheral end of the disc-shaped end wall through a generally arc-shaped bent part, and the outer peripheral wall is connected to the pump impeller, A piston plate that is axially movable and is connected to the turbine impeller is disposed between the turbine impeller and the front end wall, and a friction surface that faces the facing of the piston plate is formed on the rear surface of the front cover end wall. In the torque converter with a lock-up clutch provided by the above, the entire bent portion is extended forward from the end wall so that the inner diameter surface of the bent portion is extended forward by approximately the machining allowance than the friction surface during pressing of the end wall. The front cover shape of a torque converter with a lock-up clutch is characterized by being formed into an arc shape so that the inner diameter surface smoothly connects to the friction surface after machining.
