Abstract
An angle adjuster (71) is equipped with a first arm (1) provided with a winding-and-tightening member (5) and a second arm (10) provided with a rotation shaft portion (13). As seen in the axial direction of the rotation shaft portion (13), one end portion (5a) and the other end portion (5b) of the winding-and-tightening member (5) are provided at the first arm (1) in a manner in which they are separated from each other. The first arm (1) and the second arm (10) are connected so that the second arm (10) is rotatable centering the rotation shaft portion (13) in a state in which the winding-and-tightening portion (6) of the winding-and-tightening member (5) is wound on the outer peripheral surface (13a) of the rotation shaft portion (13). It is configured so that a rotation of the second arm (10) by a frictional force (SM) and (GM) generated by a rotational movement of the second arm (10) in a forward rotation direction (S) or a reverse rotation direction (G) is allowed or prevented.
