Then, air is supplied from a body compressor and the elastic ring 9 of the water holding part is spread to fix a seal and the water holding part 6. Water is supplied from a water intake 10 to detect a necessary water level through an air vent 11, and then the water feeding is stopped. Handles 14 and 15 are operated to move and rotate the flaw detecting part 5 up and down freely and the ultrasonic flaw detection is carried out. The flaw detecting part is lowered to the fixation position of the water holding part and the supply side of the water intake 10 is opened to discharge the water around the flaw detecting part.
