In an exhaust gas recirculating device for an internal combustion engine, an EGR gas introduction port (32) for feeding EGR gas to an intake passage (20) includes an inlet end and an outlet end, and has a cross sectional area progressively increasing from the inlet end to the outlet end, the outlet end (49) opening out at an upper part of the intake passage. Because the EGR gas introduction port has a cross sectional area progressively increasing from the inlet end to the outlet end thereof, and the outlet end of the EGR gas introduction port opens out at an upper part of the intake passage, even when an intake flow is blown back from the engine main body, carbon and oil that may be contained in the EGR gas can be prevented from being deposited in the EGR gas introduction port, and this prevents the clogging of the EGR gas introduction port. |
