(1)項又は第(2)項記載の回転探傷装置。[Claims for Utility Model Registration] (1) A rotary disk that rotates around the central axis of a material to be inspected having a circular cross section, and a sensor attached to the rotary disk, the rotary disk being rotated. In a rotary flaw detection device that detects defects on the surface of the inspected material by rotating the sensor around the inspected material, the sensing part of the sensor is made to face the surface of the inspected material. a sensor holder for holding the sensor, and a mounting member for attaching the sensor holder to the rotary disk in a manner that allows the sensor holder to float but brings the sensor holder into face-to-face contact with the surface of the inspected material. and a shock absorber for absorbing shock, which is provided between the mounting member and the rotary disk to suppress floating of the sensor holder. (2) The mounting member includes a support rod having one end attached to the rotary disk, and a movable arm having an intermediate portion attached to the other end of the support rod so as to be pivotable, and the sensor holder is , a balance weight is attached to one end of the movable arm, a balance weight is attached to the other end of the movable arm, and the shock absorber is associated with the utility model registered claim (1). The rotary flaw detection device described. (3) The rotary flaw detection apparatus according to claim 1 or 2, wherein the shock absorber is a cylinder oil damper. (4) The shock absorber is an earthquake-proof rubber block, which is the scope of the utility model registration claim.
The rotary flaw detection device described in paragraph (1) or paragraph (2).
