Abstract

PURPOSE: To prevent the occurrence of chattering and beat sound by moving a motor and a adsorption surface of an attracting member in such a manner as to adhere closely to each other to put the adsorption surface into a stable contact condition.
CONSTITUTION: A fixing hole 72a of a fixing leg 71a of a stator 7a in an electromagnetic attracting mechanism 7 is larger than the outer diameter of a cylinder portion 21a of a flange collar 21, and smaller than the outer diameter of a flange 21b and a washer 22. The thickness of the fixing leg 71a is smaller than the length of the cylinder portion 21a, whereby when the fixing leg 71a is fixed to a brake case 6 at four places thereof by the collar 21, the washer 22 and a screw 8a, the stator 7a is freely movable within a fixed range in direction of attraction and rotation.
