Claims

[Scope of claim for utility model registration] A case consisting of a plurality of linear cylindrical bodies connected in a foldable manner, and a measuring tube housed within the case and having a U-shape as a whole, with upper and lower parts. A first connecting body having a U-shaped passage that removably connects the lower ends of these straight pipe parts; and a first connecting body having a U-shaped passage that removably connects the lower ends of these straight pipe parts; such a measuring tube, comprising: a second flexible connecting body; and a second flexible connecting body housed in a case, mutually displaceable along the straight pipe portion of the measuring tube, and coated with luminous paint. A scale member having a scale, a pipe fitting attached to the top end of one straight pipe section, a liquid stored in the measuring tube, and a luminous paint applied to the liquid stored in the other straight pipe section. 1. A pressure measuring device comprising: a floating float, and a case configured such that a scale member on a straight pipe portion can be viewed from the outside.
