PROBLEM TO BE SOLVED: To absorb even vibration other than vibration in a spring shaft direction, in a vibration control structure using a disc-spring-shaped spring.SOLUTION: A vibration control unit includes a spring 4 and an elastic body 5. The elastic body 5 is formed of an elastic member into a cylindrical shape, and has a characteristic that the spring rate in an elastic body radial direction is lower than the spring rate in an elastic body shaft direction. The spring 4 and the elastic body 5 are coaxially arranged. Consequently, the spring 4 absorbs vibration in the shaft direction of the vibration unit 3, and the elastic body 5 absorbs vibration in a radial direction of the vibration unit 3. |
