Description

  The present invention relates to a level used by attaching a rod-like or pipe-like member having a circular cross section, such as a handrail or a handrail support member.

Conventionally, as a level used to detect the level and verticality of objects to be detected such as construction members in construction work, etc., liquid with a slight air bubble in a sealed small container A structure in which a bubble tube for detecting a tilt in a first direction of a structure in which a gas is enclosed and a bubble tube for detecting a tilt in a second direction orthogonal to the bubble tube are widely used (for example, Patent Document 1). reference.).

  By the way, since the above-mentioned conventional level is not provided with a mounting means for the building member in the main body, it is used by placing the level on the building member or holding the level in hand. There is a problem in terms of detection accuracy and operability because it is necessary to use it according to the detection target.

In order to solve this problem, a level has been proposed in which the main body has a clip structure so that it can be used by attaching it to a member having a circular cross section such as a rod or pipe. (See Patent Document 2) .
While this level has the advantage that it can be used by mounting it on a member with a circular cross section that cannot be used by placing the level, the location of the bubble tube is limited. In addition, when attaching and detaching the level to or from a member with a circular cross section, it is necessary to hold the clip each time, especially when a member with a different thickness is to be detected. There was a problem that the operability deteriorated.
