Summary:PROBLEM TO BE SOLVED: To provide a circularity measuring device capable of measuring the circularities of through-holes formed in inner rings accurately and inexpensively, in the shape of total number inspection on a production line. SOLUTION: The circularity measuring device includes a table 9 on which an inner ring 2 having a through-hole 5 is arranged, a measuring head 6 of an air micrometer which is inserted from above into the through-hole 5 of the inner ring 2 arranged on the table 9, a weight 10 put on the upper surface of the inner ring 2 arranged on the table 9, a vertical drive mechanism 11 for moving the weight 10 up and down, and a rotation drive mechanism 12 for relatively rotating the table 9 and the measuring head 6 on the occasion of measurement.
