Claims

[Scope of Claim for Utility Model Registration] A probe that is acoustically coupled to a test material with a substantially circular cross section via a couplant, and a probe that is movable in the radial direction and has a supply port that allows water to be supplied from the outside on the inner diameter. A fixing member having an anti-rotation structure and a through hole through which the test material can be inserted so as to be movable in the axial direction; a rotary member that has a circumferential groove for communicating with the probe and a communication hole from the circumferential groove and rotates together with the probe; and a rotating member that holds the fixed member movably in the axial direction; A rotary ultrasonic flaw detection device comprising: a support member that can be fixed such that a gap between the fixed member and the rotating member is a predetermined value; A rotating ultrasonic flaw detection device characterized by forming a spherical surface on the outer diameter of the device.
