PROBLEM TO BE SOLVED: To provide a fitting structure that can cause two members to firmly fit to each other and to be easily separated from each other.SOLUTION: A gear-side fitting part 52 inserted into a fitting hole 45 of a stirring member-side fitting part 41 is provided with a snap fit 54 extending in a withdrawal direction reverse to an insertion direction from the tip of the gear-side fitting part 52, such that when the gear-side fitting part 52 is inserted into the fitting hole 45 and a toner stirring member 33 and a stirring driving gear 34 fit to each other, a latch pawl 55 of the snap fit 54 is fit into a locking hole 46 communicating with the fitting hole 45 to be locked therein. This structure can prevent withdrawal of the stirring driving gear 34 from the toner stirring member 33 and maintain a firm fitting state between the toner stirring member 33 and stirring driving gear 34. Since a simple operation of only inserting a locking release operation tool 60 into the locking hole 46 to push the latch pawl 55 can release the locking of the latch pawl 55 into the locking hole 46, the toner stirring member 33 and the stirring driving gear 34 can be easily separated from each other.SELECTED DRAWING: Figure 12 |
