Title: Vibration reducing system for internal combustion engine

Abstract: A vibration reducing system for an automotive internal combustion engine vehicle. The vibration reducing system comprises an elastic member, and a rotating member driven through the elastic member by a rotating shaft of the engine. Here, the elastic member and the rotating member are arranged such that one of frequencies obtained by multiplying a rotational frequency of the rotating shaft of the engine which is operated idling engine operating condition by a value (a natural number/2) is within a range between a frequency of antiresonance for a rotational fluctuation of the rotating shaft of the engine which antiresonance is generated under a resonance generated by the elastic member and the rotating member and a frequency of antiresonance for roll vibration of the engine which antiresonance is generated under a resonance generated by the elastic member and the rotating member.
