装置。 In a rod-type flaw detection device that performs eddy current flaw detection on the inner surface by inserting it into the inner surface from one end of a cylindrical member such as a steel pipe,
The support rod inserted into the cylindrical member is constructed of a double cylinder consisting of a non-rotating outer cylinder and a rotating inner cylinder with a flaw detection head at its tip, and the inner cylinder is rotated while supporting this non-rotating outer cylinder. A plurality of rotary flaw detection units each having a rotation drive unit for moving the flaw detection unit are arranged side by side, and a slide mechanism that integrally slides the plurality of rotary flaw detection units in the direction in which the flaw detection units are arranged in parallel; An internal eddy current flaw detection device comprising an axial movement mechanism for lowering a flaw detection part and moving a support rod in an axial direction.
