Claims

[Scope of Claim for Utility Model Registration] 1. An inner cylinder in which a probe is fitted and fixed and a couplant supply passage is provided, and an inner cylinder that is pivotally supported on the outside of the inner cylinder and that is connected to the transducer surface of the probe. A pair of control rollers that adjust the distance between the control rollers and the surface to be inspected to a constant distance, and a frame that accommodates an inner cylinder so as to be movable up and down and pivotally supports a pair of guide rollers at equally spaced positions on both sides of each control roller. 1. An ultrasonic probe holding device comprising: an outer frame rotatably supporting a frame; 2. The ultrasonic probe holding device according to claim 1 of the registered utility model claim, in which the fixed gap between the transducer surface and the surface to be inspected is set within a range where acoustic loss due to couplant is small.
