Rotational transmission structure and image forming apparatus

Abstract

To provide a rotation transmission structure that can reduce a force required for the fitting between a first member and a second member compared with that in a case where a first member is movable only in an urging direction of an urging member and the opposite direction.SOLUTION: A rotation transmission structure has: a first member that is provided on a rotating body, and has a plurality of straight teeth arranged along an axial direction of the rotating body and side by side in a circumferential direction; a second member that is provided on a movable body moving in the axial direction of the rotating body, and has a plurality of straight teeth arranged along the axial direction of the rotating body and side by side in the circumferential direction, the second member fitting to the first member when the movable body approaches the rotating body to transmit the rotation of the rotating body to the movable body; an urging member that urges the first member to a side of the movable body; and a rotating mechanism that is provided between the first member and the rotating body, and rotates the first member when the first member moves toward the rotating body.SELECTED DRAWING: Figure 2
