An evaporated fuel purge system comprises: a fuel tank (10); a canister (12) for absorbing and separating an evaporated fuel discharged from the fuel tank; an inhalation path (210) for an internal combustion engine (2) for mixing the evaporated fuel separated from the canister with the fuel for combustion; a purge path (16) for enabling the canister to be in contact with the inhalation path; an ejector device (14) arranged on the purge path; and fluid driving devices (13, 113). The ejector device includes a nozzle unit (140) for accelerating the external fluid. The fluid driving device transports the outside air corresponding to the external fluid, and is introduced to the inside of the nozzle unit. Provided is an evaporated fuel purge system, which is not required for a flame-retardant structure. A purge pump does not increase the flow resistance of the evaporated fuel. |
