<P>PROBLEM TO BE SOLVED: To provide a driving device, simple in constitution, preventing increase in engagement noise and abnormality of rotation transmitting accuracy due to inclination of axis of a large-bore gear, compact and having high durability. <P>SOLUTION: When a driving motor 1 is rotated in the direction of an arrow A, a drum driving gear 2 is rotated in the direction of an arrow B by meshing of a gear part 4a of a rotating shaft 4 and a gear part 2a of a drum driving gear 2. The vicinity of the meshing part of the drum driving gear 2 receives the force in the direction of approaching the driving motor 1 by the thrust force caused by an angle of torsion of a helical gear. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
