An exhaust gas recirculation system includes a housing, first and second valves, an actuator, a cam member coupled with the first valve to be in synchronization therewith and receiving power of the actuator to rotate, and a link member coupled with the second valve to be in synchronization therewith and receiving power of the actuator through the cam member to rotate. The cam member includes a cam groove, an open end part formed on one end side of the groove in its formation direction and opening outward of the cam member, and an overlapping part overlapping with the actuator. The link member is driven to rotate along the groove in synchronization with rotation of the cam member. The link member includes a roller guided along the groove. |
