。 The probe is equipped with a frame formed on the probe body, two leaf springs protruding from the body in a curved manner, and a rotation stopper provided between the frame and the rotation shaft so that the probe can rotate freely within a specific range. A probe is attached to each probe, and a transmitting transducer and a receiving transducer are attached to the probes in the front and rear directions of the ultrasonic transmission and reception direction, respectively, so that the ultrasonic beam axis hits the side surface of the bolt to be inspected diagonally and is reflected. An ultrasonic flaw detection probe for inspecting specially shaped bolts having a slit portion, which is arranged so as to intersect at the lower part of the neck of the bolt.
