<p>PROBLEM TO BE SOLVED: To reduce a squeak caused by a change of a support to a rotation rigid body mode by setting a fixing position by a mounting bolt on the support asymmetrically against a center axis of the support along a radial direction of a rotor. SOLUTION: A fixing position by a mounting bolt on a support 22 is asymmetrically set against a center axis C of the support 22 by using tightening holes 24, 26 at an asymmetrical position 26, 27 provided on the support 22. Thereby, a restricting force by the mounting bolt becomes asymmetrical against the support center axis C. As a result, a vibration load applied to right and left fixing positions becomes a force of which a size is different from each other and a direction is contrary when a vibration generated on a friction surface is transmitted to the support 22. So, an effect for suppressing vibration exciting force around the support center axis C is generated and a rotation rigid body mode of the support 22 can be damped. Accordingly, a squeak caused by a change of the support 22 to the rotation rigid body mode can be reduced.</p> |
