制御装置。 It is equipped with a main hydraulic circuit that connects the pump built into the torque converter and the oil chamber of the direct coupling clutch, and a sub-hydraulic circuit that is connected between the pump and the clutch oil chamber in parallel with the main hydraulic circuit, The main hydraulic circuit includes an electromagnetic switching valve that is switched to a communication position based on a clutch actuation signal, and pressure increasing means that gradually increases the pressure in the main hydraulic circuit from a low pressure toward a set pressure in the communication position of the electromagnetic switching valve. The auxiliary hydraulic circuit is provided with a low pressure operating valve that communicates the circuit with the clutch oil chamber only in the low pressure range of the main hydraulic circuit, and a low pressure operating valve that allows oil to flow only in the direction toward the clutch oil chamber. A direct clutch control device for a torque converter, characterized in that it is provided with a check valve.
