Claims

[Scope of utility model registration request]

In a jig for measuring the inner diameter of an annular member that is an object to be measured, the annular member has a substantially conical tapered surface portion into which the inner peripheral surface of the annular member is fitted in close contact with the inner circumferential surface thereof, and the annular member is fitted into the substantially conical tapered surface portion. A jig for measuring an inner diameter dimension of an annular member, characterized in that the inner diameter dimension of the annular member is estimated based on a natural stop position of the inserted annular member on the substantially conical tapered surface portion.
