PROBLEM TO BE SOLVED: To provide a fuel injection device for an internal combustion engine of a vehicle avoiding deterioration of drivability or the like with a simple construction even when a fuel injection valve for every cylinder is similarly clogged. SOLUTION: Target speeds of the vehicle according accelerator openings are memorized beforehand. It is determined based on rotation speed, an accelerator opening and a change gear ratio whether or not the vehicle is traveling at a high constant speed (steps 150-170). When the vehicle is determined to be traveling at the high constant speed, the memorized target vehicle speed is obtained from the detected accelerator opening, and when an actual vehicle speed is slower than the target vehicle speed, it is determined that injection from the fuel injection valve 21 is lowered (steps 180, 190). When the injection from the fuel injection valve 21 is lowered because of clogging, a fuel injection quantity is corrected for increase and injection timing is advanced (steps 200, 210).
