PROBLEM TO BE SOLVED: To provide a fuel injection vibration reducing device capable of reducing vibration caused by fuel injection of an injector. SOLUTION: This fuel injection vibration reducing device for the internal combustion engine has a fuel injection structure vibrating by shock force generated by operation of an internal mechanism 12 and vibrating by the injector 10, a natural frequency variable means 31 for changing natural frequency of the fuel injection structure, and a natural frequency control means (step S21) for controlling in such a way that natural frequency of the fuel injection structure is deviated from frequency for making shock composition force generated by interference of shock force the maximum value when shock force is generated for a plurality of times within minute time.
