-f1327fl As shown in Figure 3, a surface flaw inspection device that detects flaws using surface waves having a frequency in the ultrasonic range is used.As shown in Figure 3, surface waves use the law of refraction of sound waves. The ultrasonic wave transmitted by the ultrasonic transducer 1 can be generated on the surface of the steel plate 2 by making it obliquely incident on the steel plate 2 at an incident angle θI with a refraction angle of 90 degrees. The incident angle θi is approximately 30 degrees when the ultrasonic wave is incident on the steel plate 2 from the water 3 as shown in Fig. In flaw detection using surface waves, which are concentrated at a depth of up to 100 mm and can effectively detect surface flaws, surface wave pulses are propagated to the surface of the object, reflected at the surface flaws, Ultrasound 1 as a transmitter/receiver! Detects surface wave pulses that return to the surface, making it possible to detect surface flaws.

3, surface wave pulses can be transmitted and received, and surface flaws can be detected. Therefore, the tire-shaped ultrasonic probe 12 is fixed using a suitable holding means,
Either the tire-shaped ultrasonic probe 12 is pressed against the large-diameter steel pipe 13 and the large-diameter steel pipe 13 is run, or the tire-shaped ultrasonic probe 12 is mounted on a cart that runs along the large-diameter steel pipe 13. If the cart is run with the tire-shaped ultrasonic probe 12 pressed against the large-diameter steel pipe 13, the large-diameter steel pipe 1

用いられている。In inspecting surface flaws using surface waves using the tire-shaped ultrasonic probe 12, it is important to maintain a constant efficiency of transmitting and receiving surface waves to and from the surface of a steel pipe, etc. It is important to make the ultrasonic probe 12 closely follow the movement of the surface of the steel pipe, etc., and to press it against the surface with a constant pressure. Conventionally, a spring or an air cylinder device has been used as a means for causing an ultrasonic probe such as a tire-shaped probe to follow the surface of a subject and press it with a constant pressure.
［発明が解決しようとする問題点］
しかしながら、Ｊ：、記スプリングもしくはエアシリン
ダ装置をタイヤ型超音波探触子を用いた表面波による表
面疵検査装置に用いる場合には、以下の欠点がある。[Problems to be Solved by the Invention] However, when the spring or air cylinder device described in J. is used in a surface flaw inspection device using a surface wave using a tire-shaped ultrasonic probe, there are the following drawbacks. .
（ａ）スプリングは、ストロークを大きくとることがで

従できない、すなわち、探触子が被検体から離れてしま
うか、もしくは探触子が被検体と該探触子の支持体の間

り得る。(a) Since the spring cannot take a large stroke, if the curve of the test object is large, it will not be able to follow this bend, in other words, the probe will move away from the test object, or the probe will not move away from the test object. In some cases, the probe may be strongly pinched between the probe and the support of the probe, leading to its destruction.

への表面波の送受信の効率が安定しない。(b) The air cylinder device has a slow response to the movement of the surface of the subject, and in a system in which the tire-shaped ultrasonic probe is fixed and the subject is moved to inspect the surface, The relatively small amplitude but high-speed vibrations of the specimen that occur during the process also allow a tire-shaped ultrasonic probe to be attached to a trolley that runs along the specimen, and this trolley is driven to inspect the surface for defects. In this method, the pressure of the tire-shaped ultrasonic probe against the surface of the specimen is reduced due to the relatively small amplitude but high-speed vibration of the support of the tire-shaped ultrasonic probe caused by the running of the cart. The efficiency of transmitting and receiving surface waves to and from the surface of the object is unstable.

As an invention made for the purpose of
Although there is a device for pressing a probe using a multi-stage air cylinder device (No. 128241), this multi-stage air cylinder device has the disadvantage that it has a complicated structure and is very difficult to handle.

It is possible to absorb the vibrations of the support body due to this, that is, the low-speed vibrations with large amplitudes, by expanding and contracting the air cylinder device. Therefore, according to the present invention, by using a simple and easy-to-handle UI structure, the tire-shaped probe can be made to follow the surface of the subject well and pressed with a constant pressure, and the surface of the tire-shaped probe can be pressed against the surface of the subject with a constant efficiency.
