The washer fluid is sprayed onto the front window glass through the nozzles on the front wall top cover; it is sprayed onto the rear window glass through the nozzles on the rear doors.

2 is a plan view of the injection part 20 of the liquid storage device 1; As shown in FIG. 2 and FIG. 3 , the injection channel 21 is a tubular channel inclined upward. The injection port storage tank 22 is constituted as an approximately cubic shape whose bottom surface extends from the bottom end edge 211 of the injection channel 21 to the vertical direction of the bottom end edge 211 and simultaneously expands to the length direction of the bottom end edge 211. The specified capacity (for example, 300cc) or more. The injection port 23 has a cylindrical shape and is integrally formed approximately in the middle of the top surface of the injection port reservoir 22 .

In addition, a floating body holder 24 is arranged in the injection port 23 . The float holder 24 is formed in a bottomed cylindrical shape with an upper opening, its outer diameter is slightly smaller than the inner diameter of the injection port 23, and its height is slightly lower than the inner bottom surface of the injection port reservoir 22 from the upper end of the injection port 23. up to the height. The float holder 24 is disposed so as to be fitted into the bottom surface of the inlet tank 22 from the inlet 23 . Specifically, a burring extending radially outward is formed at the upper end of the floating body holder 24, and the bottom surface of the burring overlaps with the top surface of the burring extending radially outward formed at the upper end of the injection port 23, thereby floating The body holder 24 is supported by a flange at the upper end of the injection port 23 .

A disk-shaped floating plate (floating body) 25 is accommodated in the floating body holder 24 . The floating plate 25 is configured such that its outer diameter is smaller than the inner diameter of the floating body holder 24 and can float on the liquid surface in the floating body holder 24 . In addition, an annular protrusion 26 protruding inwardly of the floating body holder 24 is formed on an upper portion of the inner wall portion of the floating body holder 24 . The ring-shaped protrusion 26 can be used as a filling mark indicating that the cleaning liquid has been filled on the one hand, and on the other hand, it is used to prevent the floating plate 25 from rising.

In addition, both the floating body holder 24 and the floating plate 25 are members made of a mesh material through which liquid can pass. Thus, the liquid in the floating body holder 24 can flow into the inlet liquid tank 22 through the cylindrical wall and the bottom of the floating body holder 24 and the floating plate 25 .

In addition, since the upper inner wall of the floating body holder 24 is provided with an annular protrusion 26, when the floating plate 25 rises to the vicinity of the annular protrusion 26, it indicates that the cleaning liquid has been filled. Therefore, it is very easy to judge that the cleaning liquid has been filled. status. In addition, even if the cleaning liquid is excessively injected, since the annular protrusion 26 can prevent the floating plate 25 from continuing to rise, the floating plate 25 will not be pushed to the outside of the floating body holder 24 by the cleaning liquid.

In addition, since the cleaning liquid flows into the inlet tank 22 through the floating body holder 24 and the floating plate 25 made of mesh material, it is also possible to prevent foreign matter from entering the storage device 1 .

In the above-mentioned embodiment, the bottom surface of the inlet reservoir 22 is formed in a substantially square shape, but it is not limited thereto, and the bottom surface of the inlet reservoir 22 may also be a polygonal, circular, elliptical, or other shape that expands around. .

In addition, in the above-mentioned embodiment, the floating body holder 24 and the floating plate 25 have a mesh structure, but it is not limited to this, as long as it is a structure that allows liquid to pass through, for example, the floating body holder 24, the floating plate Slits, small holes, etc. are formed on the 25.
