Claims

[Scope of utility model registration request]

In a probe holding device that performs ultrasonic flaw detection by being fixed to a feeding device that is movable in the axial direction of a circular mound face attached to a rotary drive device, it is attached by a coil spring seated on the side of the fixed member that is fixed to the feeding device. The wheels are pivoted on the four corners of the mounted frame,
Mounted in the same direction as the wheel axis, the outer cylinder of the probe container is pivotally supported so that it can tilt, a rotating mechanism is provided on one shaft, a fixing mechanism is provided on the other shaft, and the outer cylinder is screwed onto the outer cylinder. The inward flange of the inner cylinder of the probe container, which is biased by a coil spring compressed between the lid and the lid, is built into the inner cylinder and engages with the tip flange of the bar probe in a liquid-tight manner. The ultrasonic flaw detection method is characterized in that a cavity is formed between the tip end surface of the inner cylinder and the front surface of the probe, and a pipe for supplying couplant is provided that opens into the cavity. contactor holding device.
