Claims

[Scope of utility model registration request]

An instrument for measuring the inner diameter of a cylindrical object, in which at least one end face is a circumferential end face perpendicular to the cylinder axis, one end is a fixed measurement terminal, and the other end is a telescopic mechanism that expands and contracts according to the size of the inner diameter to be measured. A rod-shaped measuring element, which is a movable measuring terminal, and both terminals of the rod-shaped measuring element attached to the rod-shaped measuring element are placed at a predetermined equidistant position from the circumferential end surface perpendicular to the cylindrical axis of the cylindrical object. a positioning mechanism that is brought into contact with the inner surface, and a support that is slidably attached to the rod-shaped measuring element and is perpendicular to the rod-shaped measuring element and is located at a position equidistant from the rod-shaped measuring element, by expanding and contracting the movable measuring terminal. two contact parts that sandwich the movable measurement terminal and simultaneously contact the inner surface of the cylindrical object on both sides of the movable measurement terminal, and the cylinder detected by the rod-shaped element connected to the rod-shaped measuring element. 1. An inner diameter measuring device for a cylindrical object, comprising a mechanism for displaying the length of the inner diameter of the cylindrical object.
