Exhaust gas recirculation apparatus

An exhaust recirculation apparatus including:

• a housing formed with an inlet port to take in exhaust gas discharged from an engine, an outlet port to discharge a part of the exhaust gas to an intake system of an engine so that the exhaust gas is mixed in intake air, and a communication passage to communicate the inlet port and the outlet port;
• a seat provided in the communication passage;
• a drive shaft having one end on which a valve is attached, the valve being configured to come into and out of contact with the seat;
• and
• an actuator to move the valve through the drive shaft,
• wherein the actuator includes:
• a coil;
• a rotor to be driven to rotate when the coil is energized with electric current;
• and
• a converting mechanism to convert rotational movement of the rotor into stroke movement of the drive shaft to bring the valve into contact or out of contact with the seat,
• wherein the drive shaft includes a stopper configured to contact with a protrusion of the rotor when the valve is placed in a full closed state, and
• wherein the stopper includes an end face that will contact with the protrusion and the protrusion includes an end face that will contact with the stopper, each of the end faces being slanted with respect to a stroke direction of stroke movement of the drive shaft.
