PROBLEM TO BE SOLVED: To control appropriately the correction amount of the amount of fuel injection corresponding to purging by considering the affection of evaporative fuel from a fuel tank. SOLUTION: In this device 20 for controlling the amount of fuel injection that corrects the basic amount of fuel injection in accordance with the corrected amount of purging that considers the affection of purging from a canister 11, there are provided first correction means 21 and 23 for identifying the amount of air flow and the amount of fuel flow respectively in accordance with the amount of purge flow from the canister 11 according to the desorption characteristic of the canister 11 and performing a feedback control for the corrected amount of purging based on the identification result, second correction means 21 and 24 for performing a feedback control over the corrected amount of purging based on a change of an exhaust and fuel ratio, and performing control means 21 for prohibiting performing a feed forward control by the first correction means when the pressure in a fuel tank 9 exceeds a predetermined allowable range and allowing performing the feed forward control by the first correction means when the pressure is within the range.
