′−タ。A pump impeller and a turbine runner are arranged to face each other with the stator wheel in between, the pump impeller is connected to the crankshaft via a converter cover, the turbine runner is connected to an input shaft, and the stator wheel is connected to the crankshaft via a one-way clutch. The lock-up piston, which is connected to the vehicle body side member and has a clutch facing fixed to its peripheral edge and rotates together with the turbine runner, is fitted onto the input shaft so as to be able to slide freely in the axial direction, and the pump impeller and turbine runner form one lux converter chamber. A lock-up chamber is defined by the converter cover and the lock-up piston, and hydraulic oil at a higher pressure than the hydraulic oil supplied to the torque converter chamber is supplied to the lock-up chamber to provide a non-lock-up state. In a torque converter with a lockup that drains and creates a lockup state,
Consisting of at least a pair of short cylindrical members that move relative to each other in the axial direction according to the relative movement of the converter cover and the lock-up piston in the axial direction at the initial stage when the lock-up is released,
A constriction part with a drain flow path, a converter cover,
A torque converter with a lock-up, which is interposed between lock-up pistons, and is characterized in that the flow of hydraulic oil in the lock-up chamber is significantly restricted only at the initial stage when the lock-up is released.
