<p>PURPOSE: To smoothly carry out the release and connection of a clutch by installing a slide assisting member between one hole part on the rotary members on an input shaft side and an output shaft side and the projection part on a movable member. CONSTITUTION: When an electric coil 23 in a worm wheel 13 is energized, the clutch plate 24 of a magnetic body is attracted by the worm wheel 13, and is brought into contact. On the contact surface, an uneven part for engagement is formed, and the driving force of an input shaft 11 is transmitted to an output shaft 16, and a clutch is connected. When the electric coil 23 is deenergized, the clutch plate 24 is urged to a pinion gear 14 side by a coil spring 25, and the engagement of the clutch is released. Between the projection part 29 of the clutch plate 24 and the hole part 28 of the pinion gear 14, cylindrical slide assisting members 26 are uniformly arranged, and the axis line passes through the center of a rorary shaft 21, and crosses at right angle with the rotary shaft. Accordingly, when the clutch plate 24 slides, the slide assisting member 26 smoothly slides through the rolling, and the engagement and release of the clutch can be carried out smoothly.</p> |
