| description | PROBLEM TO BE SOLVED: To provide a method and an apparatus for ultrasonic flaw detection of shaft members. SOLUTION: Flaw-detection ultrasonic waves of vertical waves are made to be incident onto a face of a shaft member from a phased array probe mounted rotatably in the circumferential direction of the shaft member. The ultrasonic waves perform flaw detection in the circumferential direction of the shaft member, while a part of the shaft member at which a rotating member is press-fitted is being scanned in the axial direction of the shaft member by a sector scan method. This apparatus includes the phase array probe for transmitting flaw-detection ultrasonic waves of vertical waves; wedges for fixing the phased array probe; a mechanism for holding the wedges at a shaft end of the shaft member for performing ultrasonic flaw detection rotation-freely, in the same direction of the rotating direction of the shaft member; and a detector of the rotation angles of the wedges.
