Abstract

PURPOSE: To provide an oscillating mechanism which moves a magnetic body in its conveying direction at every half-period, near the conveyance route of the magnetic body, and mount an axial-direction magnetic field detecting element at the end of the oscillating piece of the oscillating mechanism, thereby detecting circumferential flaws and axial flaws misultaneously.
