<P>PROBLEM TO BE SOLVED: To provide a moving body driving device which can change moving speed of moving body and a driving force for driving the same without controlling the rotational speed of a drive motor. <P>SOLUTION: The moving body driving device is comprised of a pulley 10. The pulley 10 has a cable 6 wound thereon, is driven for rotation by the drive motor, and has a groove 14 formed in an external surface thereof, the groove being spirally formed along a rotating shaft and having the cable 6 wound thereon. According to the structure of the pulley 10, a winding location at which the cable 6 is wound on the pulley is axially moved by taking-up/supplying the cable 6 according to the rotation, and the diameter of the pulley at the winding location is axially varied. <P>COPYRIGHT: (C)2007,JPO&INPIT |
