PURPOSE:To provide a driving device capable of positioning an object to be driven with high precision, sufficiently obtaining the desired thrust even when a drive source such as a motor has a small output, and freely setting the moving speed of the object. CONSTITUTION:Part of a belt-like member 42 applied with the driving force by a drive source such as a motor 37 is connected to an object 43 to be driven to form a driving device for moving the object 43. A rotor 1 having a large- diameter section 1a and a small-diameter section 1b is fitted to the object 43, the large-diameter section 1a is coupled with the belt-like member 42, another belt-like member 5 is stretched in parallel with the belt-like member 42, it is coupled with the small-diameter section 1b, the diameter ratio between the large-diameter section 42 and the small-diameter section 1b is set, thus the deceleration function is provided. |
