PROBLEM TO BE SOLVED: To provide a rotation force transmission mechanism capable of reversibly rotating and stopping one rotation body without stopping a drive source.SOLUTION: A rotation force transmission mechanism 30 comprises: a first rotation force transmission path which transmits a rotation force in a first direction to a first rotation body 35; a second rotation force transmission path which transmits a rotation force in a second direction to the first rotation body 35; and a third rotation force transmission path which transmits a rotation force to a second rotation body 31. In the first rotation force transmission path, a torque limiter 50 which is provided between the first rotation body 35 and the drive source, connects the first rotation body 35 and the drive source in a manner of being capable of transmitting the rotation force until torque of a predetermined value is applied and disconnects them when the torque equal to or greater than the predetermined value is applied, a brake member 60 which applies the torque exceeding the predetermined value to the first rotation body 35, and a clutch member 55 which can perform switching between the state where the rotation force can be transmitted to the first rotation body 35 and the state where transmission of the rotation force is blocked in the second rotation force transmission path.SELECTED DRAWING: Figure 2 |
