Abstract

PURPOSE: To enable to readily operate at both horizontal surface and vertical surface by only one operation in a leveling instrument by providing circular orthogonal groove on the inner surface of an upper cover and mounting it on the leveling instrument.
CONSTITUTION: An upper cover 2 is molded by glass or resin, and provided with a circular orthogonal groove 4 on the inner surface thereof to communicate with each other. This is closely contacted with the bottom plate 3 to retain an air bubble 6. Then water or ether 5 is filled, and a scale line 7 is formed, and it is mounted on the horizontal and vertical end surfaces with respect to the bottom surface of the beam-like body. When the air bubble in the cross groove is equal in length, it can detect the horizontality.
