Abstract:
1. A level composed of a mounting base provided with a bubble tube measuring portion in which a liquid and a bubble are sealed, or a mounting base provided with a magnetic body is disposed inside a container case, and an opposing end portion of the mounting base is pressed to the inner surface of the container case to cause the mounting base to be pressingly fixed inside the container case in a prescribed position that allows said bubble tube measuring portion to be viewed from a window hole provided to the container case, or in a prescribed location that allows said magnetic body to be exposed from an exposure hole provided to the container case; wherein: said mounting base is configured so that a first unit that presses against the inner surface of one side of the container case and a second unit that presses against the inner surface of the opposing opposite side of the container case are slidably assembled by way of a slide mechanism; said slide mechanism is formed so that assembly contact surfaces of said first unit and second unit are formed as slope guide surfaces; the slope guide surfaces make contact with each other, the second unit is slidably configured in the slope direction with respect to the first unit, and the entire length of the mounting base composed of said first unit and second unit is variably configured; and the entire length of the mounting base performs a micromotion when the second unit performs a sliding micromotion in relation to the first unit via pressing means that presses the second unit against the first unit of the mounting base to obtain a structure in which the mounting base can be pressingly fixed inside the container case.
