  • Patent number: 11279214
    Abstract: In a driver, supposing that an angular position of the rotator in a state where a coupler coupling a link member and the rotator together is located at a rearmost position is regarded as a reference angular position, a first angular position is an angular position where the rotator is shifted from the reference angular position in a first rotation direction by an angle ?1, and a second angular position is an angular position where the rotator is shifted from the reference angular position in a second direction opposite to the first rotation direction by an angle ?2 smaller than the angle ?1. The driver has a regulating portion which does not allow the rotator to rotate in the second rotation direction from the second angular position.
