PROBLEM TO BE SOLVED: To provide a vibration reduction device of a rotating body which can exhibit a stable vibration reduction action by a simple constitution.SOLUTION: A vibration reduction device is arranged at the circumferential periphery of a rotating body 100, and comprises a mass body 2, a pair of protrusions 3, 4 formed at the mass body 2, and guide grooves 5a, 5b and 6a, 6b formed at the rotating body 100. Then, by fitting the protrusion 3 into the guide grooves 5a, 5b and the protrusion 4 into the guide grooves 6a, 6b, and moving both the protrusions along the guide grooves, the vibration reduction device can perform oscillation movement while rotating the mass body 2. |
