Abstract
A rotation transmission structure includes: a first member that is provided on a rotating body and includes a plural straight teeth extending in an axial direction of the rotating body and arranged in a circumferential direction; a second member that is provided on a moving body moving in the axial direction of the rotating body, includes a plural straight teeth extending in the axial direction of the rotating body and arranged in the circumferential direction, and is fitted to the first member to transmit rotation of the rotating body to the moving body in a case where the moving body approaches the rotating body; a biasing member that biases the first member toward the moving body; and a rotation mechanism that is provided between the first member and the rotating body and rotates the first member in a case where the first member is moved toward the rotating body.
