Claims

[Scope of utility model registration request]

A device for measuring the tail clearance between the inner surface of a tail frame of a shield frame and the outer surface of a segment assembled within the tail frame, which is provided within the tail frame so as to be movable along the axial direction of the tail frame; A main body that comes into contact with the tip surface, a first sensor that is provided on a portion of the main body that faces the inner surface of the segment and measures the relative distance to the inner surface without contact, and a first sensor that is provided on a portion of the main body that faces the inner surface of the tail frame. A tail clearance measuring device comprising: a second sensor for measuring a relative distance to the inner surface in a non-contact manner;
