MEASURING APPARATUS AND SUPPORT MECHANISM OF COLUMNAR WORK PIECE

摘要

A measuring apparatus includes a first end support portion supporting a first end of the columnar work piece; a second end support portion supporting a second end of the columnar work piece; and a measurement device having a probe which measures the columnar work piece supported by the first end support portion and the second end support portion. The first end support portion includes a first end support body attachably and detachably fitting into a centering aperture of the first end of the columnar work piece. The first end support body includes at least two cut-outs, and in a state where the first end support body is fitted into the centering aperture, an interior surface of the centering aperture is visible to the exterior through the cut-outs. The measurement device inserts the probe into the centering aperture through the cut-outs and measures the interior surface of the centering aperture.
