Abstract
A rotation transmission mechanism may include a drive wheel structured to rotate to one side, a driven wheel turned by the drive wheel to one side, and an urging member urging the driven wheel to turn to the other side. The drive wheel may include a drive teeth forming part where drive teeth structured to turn the driven wheel to the one side are provided at positions different from each other in an axial line direction, and a cam face forming part on which the driven wheel is slid. The driven wheel is provided with a driven teeth forming part where driven teeth provided at positions different from each other in an axial line direction are disposed over an angular range so that, when the drive wheel is turned to the one side, the drive teeth are sequentially abutted with the driven teeth.
