Abstract: A level having a mounting body provided with a bubble tube measuring portion disposed in a container case, the mounting body is adjusted by microrotation in relation to the container case to correct a position of the bubble tube, wherein a shaft insertion hole is provided in the container case and in the mounting body, the shaft member is disposed via the through-hole of the container case and the mounting body, whereby the mounting body can perform microrotations about the shaft member in the container case, the mounting body is provided with an elastic pressure contact portion for making elastic pressure contact with an inner surface of one side of the container case, and a tightening and pressing contact portion for making pressing contact via an adjustment screw for pressing and making contact in a sloped direction with the inner surface on an opposite side facing the container case.

Abstract: A level being one in which a mounting base 2 is configured so that a first unit 2A that presses against the inner surface of one side of the container case 3 and a second unit 2B that presses against the inner surface of the opposing opposite side of the container case 3 are slidably assembled by way of a slide mechanism S; the slide mechanism S is formed so that the assembly contact surfaces 5 and 6 of the first unit 2A and second unit 2B are formed as slope guide surfaces 5 and 6; the slope guide surfaces 5 and 6 make contact with each other, the second unit 2B is slidably configured in the slope direction in relation to the first unit 2A.

Abstract: An object is to provide a novel level in which a mounting base can be pressingly fixed in a container case in a reliable manner by a simple operation while having a simple configuration, wherein the level has excellent mass-productivity and is advantageous in terms of cost.

Abstract: An object is to provide a very novel and highly practical level in which mass productivity is good, in which the bubble position is easily corrected, and which is advantageous in terms of cost.
