PURPOSE: A vehicle fuel evaporating gas re-cycling apparatus is provided, which can minimize evaporation of gas to the atmosphere from a canister and can reduce manufacturing cost. CONSTITUTION: A vehicle fuel evaporating gas re-cycling apparatus comprises a vapor control valve(27), a vapor EGR valve unit(30), and a one-way check valve(31). The vapor control valve is installed on the vapor line(5) and is controlled by an engine control unit(16). The vapor EGR valve unit is connected to the vent-line(13) and is connected to the canister through the purge line and recirculation line(33). The vapor re-cycling valve unit is connected to a canister through the fuzzy pressure delivery lines(35). The one-way check valve is installed on the fuzzy pressure delivery lines.
