Claims (1)

[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. It has a plurality of elastic body holding parts and a plurality of oval holes on the middle circumference of the center, and a weight positioned in a part of the seal ring in the longitudinal direction of the oval hole so as to disturb the weight balance. a first seal ring and a second seal ring, and a double seal formed by providing the first seal ring and the second seal ring on the elastic body holding part so as to be movable in opposite directions and relative to each other. A seal ring for ultrasonic flaw detection characterized by comprising an approximately H-shaped elastic body constituting the ring.
