<p>PURPOSE: To obtain a slip mechanism which dispenses with a washer and others and is constructed of the fewest number of components and also which greatly facilitates molding and assembly of the components. CONSTITUTION: A gear 10 is fitted on a main body part 4 externally in such a manner that a press-in part 18 of the gear gets over an engagement part 8 of an output shaft 2. A coil spring 20 is provided between the gear 10 and a circular projecting part 6, and the gear 10 and the output shaft 2 are brought into contact by the elasticity of the coil and rotate integrally. In the case when the rotation of the output shaft 2 is hindered, sliding occurs between the press-in part 18 and the engagement part 8, between the inner peripheral surface of a through hole 12 and the outer peripheral part of the main body part 4 or between the coil spring 20 and the gear 10 or the circular projecting part 6, and the gear 10 and the output shaft 2 rotate separately.</p> |
