Claims

[Scope of utility model registration request]

In a seal ring for ultrasonic flaw detection that is attached to both sides of a rotating tank that holds a group of probes and seals the couplant, there is a hole in the center of the seal ring through which the cylindrical material to be inspected passes and the above-mentioned passage hole. A plurality of elastic body holding parts and a plurality of oval holes are provided on the circumference of the center, and a plurality of elastic body holding parts and a plurality of oval holes are provided on a part of the seal ring in the longitudinal direction of the oval hole, and are positioned so as to disturb the weight balance. A double seal ring comprising a first seal ring and a second seal ring having holes, and the first seal ring and the second seal ring provided on the elastic body holding part so as to be movable with respect to each other in opposite directions. A seal ring for ultrasonic flaw detection characterized by comprising an approximately H-shaped elastic body constituting the seal ring.
