Each holder 5 includes first and second receiving portions (9, 10). The first receiving portions (9) receive forces in a direction to push the first helical gears (3) toward backs of accommodating portions (7) by contacting parts of the first helical gears (3) when the shaft (2) and the first helical gears (3) are rotated in a certain rotational direction. The second receiving portions (10) receive forces in a direction to push the first helical gears (3) from interiors of the accommodating portions (7) to openings (8) by contacting parts of the shaft (2) when the shaft (2) and the first helical gears (3) are rotated in an opposite direction. Thus, the driving unit is assembled easily and the helical gears are held stably in both rotational directions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Driving unit and image forming apparatus using the same","description":"A driving unit (1) includes holders (5) rotatably supporting a shaft (2) and rotatably holding first and second helical gears (3, 4).
