Claims

[Claims for Utility Model Registration] 1. A penetrating rod that is inserted into a tube to be inspected for magnetic particle flaw detection and magnetizes the tube by applying electricity from electrodes connected to both ends protruding outside the tube. A plurality of pedestals are used for centering the tube to be inspected, the pedestal body having an axial dimension slightly shorter than the inner diameter of the tube to be inspected, and the cradle body having both end portions at an axially intermediate portion thereof. A penetrating bar holder for magnetic particle testing, characterized in that a support groove is provided to support the penetrating bar at the center of the tube to be inspected when the penetrating bar is placed in contact with opposing inner surfaces of the tube to be inspected. . 2. In the penetrating bar holder for magnetic particle flaw detection according to claim 1, the cradle main body and both ends thereof are separate bodies, and the both ends are adjustable in the axial direction with respect to the cradle main body. A penetrating bar holder for magnetic particle flaw detection characterized by a curved shape.
