Claims

[Scope of utility model registration request]

Two fixed measuring elements fixed to the lower surface of the measuring machine body, and two or more movable measuring elements provided on the lower surface of the measuring machine body so as to be movable up and down in the same straight line as the fixed measuring elements. , select two arbitrary three points from among the four or more contact points of the surface to be measured that these four or more contact points come into contact with, calculate the curvature of the circular arc passing through the three points for these two ways, and calculate the change. A curvature change rate measuring device comprising a calculation unit that calculates the ratio, and a display unit that displays the rate of change in curvature determined by the calculation unit.
