Figure 1 is an explanatory diagram for measuring the depth h including the thickness with a depth gauge, and Figure 2 is an explanatory diagram for measuring the thickness t with a caliper. In the explanatory diagram for measurement, the inner diameter was measured at h-t=d in two measurements.

Claims

[Scope of utility model registration request]

A main body having a flat surface on the lower surface, a depth measuring scale held in the main body so as to be movable in a direction perpendicular to the lower surface, and a thickness measuring scale having a lower end bent into an L shape and movable in a direction perpendicular to the lower surface of the main body. A thickness reference line engraved on the thickness scale, the L-shaped inner surface engraved on the thickness scale as a reference surface, and the distance from the bottom surface of the body to the thickness read from the thickness reference line. A scale, a depth reference line engraved on either the depth measuring scale or the thickness scale, and the L-shaped inner surface and depth of the thickness scale engraved on the thickness scale or the depth measuring scale. A measuring instrument characterized by comprising a depth scale whose distance from the lower end surface of the scale is read using the depth reference line.
