A vibration control mechanism 50 is interposed between a ball bearing 8 and a support section 2a of a base 2. The vibration control mechanism 50 is provided with a plurality of laminated sliding members 51, 52 and an elastic body 53. The vibration control mechanism 50 is provided with the plurality of sliding members 51, 52, and therefore has a plurality of sliding surfaces. As a result, it is possible to enhance a vibration control effect. |
