Drive apparatus

Abstract

A drive apparatus that, together with securing the lateral symmetry of the overall apparatus, minimizes the number of parts while also achieving a smooth operating state. A rotating member is provided that makes sliding contact at its outside surface with opposing portions of a belt-shaped member wrapped around each rotor to obtain a parallel state with respect to said opposing members. Thus, a driving device in the form of a motor and so on that rotates and drives said rotors can be arranged on a line extending from the center in the direction of width of a driven object. As a result, the lateral symmetry of the overall apparatus is secured. In addition, since the number of parts can be minimized, together with achieving a reduction in costs, a smooth operating state is obtained since said rotating member only makes sliding contact with said belt-shaped member.
