定用ノギス。 This is a caliper for measuring the difference in length between both sides of an angle iron, and it has a main scale with a jaw at the center in the length direction, and sub-scales that are slidably attached to both sides of the jaw of this main scale. The jigyo of the main scale is provided with a chevron-shaped recess formed from two measurement surfaces that are in close contact with the outer surfaces of both sides of the corner of the angle iron. The angle formed by the line that is perpendicular to the surface and passes through the center of the corner of the angle-shaped recess is equal, and the vernier has an angle when both measurement surfaces of the angle-shaped recess are brought into close contact with the outer surfaces of both corner sides of the angle iron. A caliper for measuring the length difference between both sides of angle-shaped steel, characterized in that a jig having a measuring surface that can be brought into contact with the tips of both sides is provided.
