Claims

[Scope of utility model registration request]

On the top surface of a flat plate on which a flexible and elastic annular article can be placed, there is a semicircular stationary half piece having a smaller diameter than the inner diameter of the annular article, and a semicircular fixed half piece that is the same size and in the opposite direction. A movable half piece that is semicircular and can be aligned with the fixed half piece to form a circle having a smaller diameter than the inner diameter of the annular article is provided so as to be movable toward and away from each other, and when the movable half piece moves away from the fixed half piece. A device for measuring the inner diameter of a flexible and elastic annular article, comprising distance measuring means capable of measuring the distance between the fixed half and the movable half when the force applied is a predetermined strength.
