A sealing device for combustion gas of an exhaust gas recirculation fan is provided to prevent leakage of exhaust gas by installing packing, and to improve sealing efficiency of separation surfaces of a carbon seal and to prevent sag of the carbon seal by installing a fixing pin to penetrate the carbon seal. In a sealing device for combustion gas of an exhaust gas recirculation fan, which is connected to a shaft of the exhaust gas recirculation fan and includes a carbon seal housing, a carbon seal(310), and a carbon seal spring(160), separation surfaces(400) of the carbon seal are connected and mated with each other, packing(320) is attached to both sides of the carbon seal, and the carbon seal and the packing are fixed to the carbon seal housing with a fixing body(300). The fixing body is a pin inserted and fixed to a first fixing body groove(330) formed to a middle of the carbon seal housing, penetrating a second fixing body groove(340) formed in an outer carbon seal housing and a clamp hole formed in the carbon seal.
