Title:
ROTATION MECHANISM, TRANSFER DEVICE, AND IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2022030009
Kind Code:
A
Abstract:
To allow a rotation member to easily relatively move in an axial direction with respect to the support shaft even when the outer diameter of the support shaft is not uniform over the axial direction.SOLUTION: A rotation mechanism comprises: a support shaft 81; and a rotation member 82 that is provided with a hole part 82a into which the support shaft 81 is inserted and rotatable around the support shaft 81. The support shaft 81 is formed such that, with its outer peripheral surface as shaft side projections 81a, shaft side recesses 81b depressed in a direction approaching a rotation center with respect to the outer peripheral surface extend in an axial direction. The hole part 82a of the rotation member 82 is formed such that, with its inner peripheral surface as hole side projections 82a1, hole side recesses 82a2 depressed in a direction going away from the rotation center with respect to the inner peripheral surface extend in the axial direction. In a state in which the shaft side projections 81a are opposite to the hole side recesses 82a2 within a range in a circumferential direction of the hole side recesses 82a2, the rotation member 82 is relatively moved in the axial direction with respect to the support shaft 81.SELECTED DRAWING: Figure 7
