PROBLEM TO BE SOLVED: To provide an angle adjuster that can prevent a second arm from rotating in a normally rotating direction to a first arm even when a load in the normally rotating direction is added accidentally to the second arm at a position of an arbitrary development angle of the second arm to the first arm.SOLUTION: A first arm 1 and a second arm 10 in an angle adjuster 60 are connected to each other so that the second arm 10 can rotate relatively to the first arm 1 around a rotary shaft part 13 in a state where a tightly-winding part 7 of a tightly-winding member 6 in the first arm 1 is wound around an outer periphery 13a of the rotary shaft part 13 in the second arm 10. The angle adjuster 60 comprises normal rotation prevention means 20 that includes a first pressing part 21, and prevents the second arm 10 from rotating in a normally rotating direction S when the first pressing part 21 presses the tightly-winding member 6 in a tightly winding direction V at a position of an arbitrary development angle of the second arm 10 to the first arm 1. |
