PROBLEM TO BE SOLVED: To provide a driving device having such structure that prevents damage of a tooth face due to torsion of a helical gear when assembling and improves assembly property. SOLUTION: This driving device is provided with a shaft 3 of a first driven gear 6 which is the helical gear and a shaft 4 of a driven gear 7 on a side plate 2 on a drive side on which a motor 1 and a driving gear 5 are mounted. The first and second driven gears 6, 7 are attached to the shafts 3, 4 before meshing with the other driving system to mesh with the driving gear 5 which is the helical gear in advance. In this driving device, the driven gears 6, 7 are meshed with the driving gear 5 independently to realize a subassembly. Consequently, assembly can be achieved while rotation load on the driven gear 6, 7 sides is small without damaging tooth faces of each gear 5, 6, 7. COPYRIGHT: (C)2005,JPO&NCIPI
