PURPOSE:To stabilize the attitude of a brake rotor and as well to aim at preventing a pad member from being eccentrically worn and as well at preventing the generation of fine vibrations upon slow braking, by satisfying the followability of the brake rotor upon application of brake force in accordance with the press-contact between the brake rotor and the pad member. CONSTITUTION:The output shaft 2 of a motor 3 is attached thereto with a brake rotor 5A which rotates in association with the rotation of the output shaft 2, and braking force is applied to one end of the brake rotor 5A by pressing a pad member 7 from both surfaces of the brake rotor 5A. The center part of the brake rotor 5A and the output shaft 2 are fitted together so that torque from the output shaft 2 may be transmitted to the rotor 5A, and as well it is made possible to swing a securing member for securing the fitted part between both rotor 5A and output shaft 2, and the rotor 5A in the directions of the output shaft 2. |
