Claims

[Scope of Claim for Utility Model Registration] (1) A rotary disk having a tube-shaped or round bar-shaped test material passing through it in the center and rotating around the test material. In a flaw detection device in which a lever having a detection end at the tip is provided so as to rotate in the direction of the material to be inspected around a fulcrum pin; The fulcrum pin is fixed to this fulcrum plate, and the fulcrum plate is moved appropriately according to the outer diameter of the material to be inspected.
