Claims

[Scope of utility model registration request]

a first arm member pair whose inner ends are rotatably pivoted symmetrically to a pivot shaft within a plane passing through the axis of the pivot shaft and pivot integrally with the pivot shaft; the first arm member pair and the above arm member pair; a spring that is interposed between the pivot shaft and biases each outer end of the first arm member pair outward; and a spring that is pivotally connected to one outer end of the first arm member pair and urges the outer end of the first arm member pair outward; a dummy sensor that slides, a second arm member pivotally connected to the other outer end of the first pair of arm members, and a connection between the other of the first pair of arm members and the second arm member. a spring interposed therebetween to bias the outer end of the second arm member outward; and a sensor pivotally connected to the outer end of the second arm member and sliding along the inner diameter surface. A scanning mechanism for the inner diameter surface.
