ABSTRACT:
An inside diameter measuring tool includes: a main body; an axially moving spindle having a male screw to be screwed to the main body; a plurality of contact pieces provided on the main body, the measuring pieces moving in a direction substantially orthogonal to the axial direction of the spindle; and a conical member interposed between the contact pieces and the spindle, the conical member advancing and retracting the contact pieces in the direction substantially orthogonal to the axial direction of the spindle. The lead of the male screw of the spindle is 1.0 mm or more and the cone angle of the conical member is less than 53 degrees. Preferably, the lead of the male screw is 2.0 mm and the cone angle of the conical member is approximately 28 degrees.
