摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic flaw detection tool capable of inspecting easily even if a bore diameter is different.;SOLUTION: An ultrasonic flaw detection tool includes: a base part where a probe of the ultrasonic flaw detection device contacts; and a projection part provided in the base part and inserted in a hole to be inspected provided on an inspection object. The hole to be inspected includes: a dish part which is connected to a principal surface of the inspection object at one end, and extends so that a diameter is reduced from the principal surface; and a connection part which connects a bottom of the dish part and a rear face of the inspection object. The projection part has a conical shape corresponding to the shape of the dish part.;COPYRIGHT: (C)2014,JPO&INPIT
