Claims

[Scope of utility model registration request]

one ends of two arms are rotatably connected to each other, and measurement surfaces are formed on these arms that face each other in a plane including the central axis of rotation,
One of the two arms has a graduation surface with an angle graduation along a line orthogonal to the rotational center axis, and one end of the ribbon extending along the angle graduation is attached by a spring to the graduation surface. A pointer for the angle scale is attached to the other end of one arm, and a winding shaft is attached to the one end for winding and unwinding the other end of the ribbon in conjunction with the rotation. An angle measuring instrument comprising two pointers that can be attached and further positioned along the angle scale.
