PURPOSE: An EGR(exhaust gas recirculation) device of an engine is provided to reduce losses of back pressures of the engine by generating small amount of the back pressures of the engine and securing enough amount of the EGR. CONSTITUTION: An EGR(exhaust gas recirculation) device of an engine comprises an exhaust pipe unit(1), an EGR port(3), and a valve flap(5). Exhaust gases pass through the exhaust pipe unit form the engine. The EGR port is penetrated through a wall of the exhaust pipe unit. The valve flap is installed in the exhaust pipe unit to be rotated. The valve flap completely opens the EGR port from a state of blocking the EGR port by being rotated. The valve flap gradually reduce a flow sectional area of the exhaust pipe unit.
