<p>PROBLEM TO BE SOLVED: To decrease impact force and impact sound applied from a braking part to a braking surface and a rotor. SOLUTION: In a braking method of bringing the braking part 53 into contact with the rotor 21 rotating about a shaft 17 to brake the rotor 53, firstly the braking part 53 is held at a first position spaced from the rotor 21 by a first distance. Then, the braking part 53 is spaced from the rotor 21 by a second distance shorter than the first distance, or the braking part 53 is held in a contact state with the rotor 21 at a degree where a substantial braking force is not applied to the rotor. Then, the braking part 53 is pressed to the rotor 21 at a degree where the substantial braking force is applied to the rotor 21.</p> |
