<p>PURPOSE:To permit the smooth selection by preventing the meshing between a worm gear on a drive side and the gear of a driven member on a driven side by the simple structure. CONSTITUTION:A driving mechanism selector device is equipped with a shaft 1 which is supported in turnable manner on a base plate and turning-driven by a turning driving source, worm gear 2 which revolves integrally with the shaft 1 and concentrically installed on the shaft 1 permitting the free shift in the axial direction, an engaging member 3 for regulating the shift range of the worm gear 2 for the base plate and a driven member 7 meshed with the worm gear 2 at the shift edge in the axial direction of the worm gear 2, and the driven member 7 can be shifted in the axial direction within a prescribed range.</p> |
