ABSTRACT:
A torque converter, which can prevent an oil pressure required for shifting a lock-up clutch from being made high, is provided. A converter chamber is formed between an outside circular-plate portion of a front cover and an impeller shell. A lock-up clutch constituted by a drive plate and a driven plate is accommodated in a clutch chamber. A lock-up piston is attached to the front cover so as to be movable axially, and partitions the converter chamber and the clutch chamber. In engaging the lock-up clutch, the pressure in the clutch chamber is made lower than that in the converter chamber; and in releasing engagement of the lock-up clutch, operating oil having approximately the same pressure is supplied into the converter chamber and the clutch chamber.
