Title:
CURVATURE MEASURING TOOL
Document Type and Number:
Japanese Patent JP2008164386
Kind Code:
A
Abstract:

To provide a curvature measuring tool adaptable to an arbitrary curvature and made compact in a simple operation.

The curvature measuring tool comprises: a measuring tool main body 10 in which a reference position 12 is set leaving a predetermined space from a curved part contact position 11 abutted on the curved part; and a movable unit 20 held rotatably on the measuring tool main body 10 and held slidably on a line passing through a rotation center. The tool is configured so as to enable measuring a distance (a) between the reference position 12 and an end of the movable unit 20 when a tangent L1 of the curved part at a main body contact point P2 where the curved part contact position 11 is abutted on the curved part gets parallel with a line connecting the main body contact point P2 and a reference point P3 coincident with the reference position 12 by sliding the movable unit 20 in a direction orthogonal to a line connecting the curved part contact position 11 and the reference position 12.
