合突起９，１０間に位置するように構成される。 FIG. 1 and FIG. 2 show the water volume level for the washer tank showing the first embodiment,
The water level 1 is constituted by a viewing tube 4 inserted and fixed into a through hole 3 bored in the upper wall of a tank 2 having an appropriate capacity. The viewing tube 4 is made of a transparent material, penetrates the through hole 3, is implanted and fixed in a substantially vertical direction via a gasket 5, and has an annular opening at the upper end extending in the longitudinal direction. Part 6
A water inlet 8 is formed by attaching a cap 7 to the end of the spout member 6, which can be opened and closed. The inner wall of the visual cylinder 4 is provided with annular engaging protrusions 9 and 10 that protrude in the inner diameter direction at a predetermined interval at the upper and lower positions, and a light specific gravity material or a hollow body, etc. are formed inside the cylinder. A colored rod-shaped float 11 made of
An annular projection 12 having a slightly larger diameter than the inner diameter of the engaging projections 9 and 10 is formed on the outer periphery of the upper end, and the lower end extends and floats in the water in the tank 2, and in this floating range (stroke A). The annular projection 12 is configured to be located between the two engaging projections 9 and 10.
なお、上記係合突起９，１０は、所望により環
状方向に対して不連続に形成されたものであつて
もよい。 The engaging protrusions 9 and 10 may be formed discontinuously in the annular direction, if desired.

ることができるようになつている。 The water volume level 1 with the above configuration is determined by detecting the level of the float 11 inserted into the viewing tube 4 through the viewing tube 4,
It allows you to know the water level in the tank 2, and the "FULL" level is displayed in advance on the visibility tube 4.
3. By providing the "EMPTY" level display 14, the amount of water in the tank 2 can be roughly understood through the water amount level 1 based on the relative position to the upper end of the float 11.

構造を構成したものである。 That is, annular protrusions 15 and 16 are formed at the upper and lower ends of the rod-shaped float 11, respectively, and each have an outer diameter that is slidable relative to the inner diameter of the viewing tube 4. A fall prevention structure is constructed in which an engaging protrusion 17 is formed that protrudes from the top, and both annular protrusions 15 and 16 are positioned and engaged so as to straddle the engaging protrusion 17.
更に、第４図は本考案に係るウオツシヤータン

水口８から逆流溢水することがない。 That is, this embodiment is similar to the float 1 in the second embodiment.
The upper end of 1 is formed into an umbrella-shaped body 15a that projects upwardly from the axis, and a plurality of protruding columns 15b are protruded from the periphery of the lower edge thereof at appropriate intervals. 15b engages with the engagement protrusion 17 on the viewing tube 4 side to prevent the float 11 from falling. According to such a configuration, when water is injected from the water inlet 8, the fall prevention structure acts as a dam and water does not backflow from the water inlet 8.

Since the fall prevention structure for the water tank water level according to the present invention is constructed as described above,
The simple engagement structure formed between the visibility cylinder and the float allows the detection of the water level in the tank to be configured without interfering with the detection of the water level, and has the effect of preventing the float from falling off. The practical effects of this are extremely large.
