PROBLEM TO BE SOLVED: To provide an angle adjuster capable of being downsized.SOLUTION: An angle adjuster 71 includes a first arm 1 provided with a winding-and-tightening member 5, and a second arm 10 provided with a rotary shaft 13. In an axis directional view of the rotary shaft 13, one end part 5a and the other end part 5b of the winding-and-tightening member 5 are provided on the first arm 1 with them being mutually apart from each other. The first arm 1 and the second arm 10 are coupled so that the second arm 10 can be rotated centered around the rotary shaft 13 in a state in which a winding-and-tightening portion 6 of the winding-and-tightening member 5 is wound around an outer peripheral surface 13a of the rotary shaft 13. The angle adjuster is so configured that frictional forces SM, GM that are generated by the rotational movement in the positive rotational direction S and reverse rotational direction G of the second arm 10 bring the rotation of the second arm 10 to be allowed or inhibited. |
