An EGR apparatus for an engine includes an EGR passage, an EGR valve, an accelerator sensor, and an ECU. The ECU compares a change amount (accelerator operating speed) per unit of time of an accelerator opening degree to a predetermined first determination value. When it is determined that a request for deceleration operation or acceleration operation is made to an engine, the ECU issues a fully closing command to the EGR valve. When it is determined that the deceleration or acceleration operation request is continued, the ECU continues to issue the fully closing command. When the deceleration or acceleration operation request is removed and the accelerator opening degree is larger or smaller than a predetermined second determination value, the ECU releases the fully closing command. |
