めて狭いという問題点があつた。(Problem to be solved by the invention) This transparent body 10 is attached to the lid body 2 by welding a glass material to the upper end of the outlet hole 8 after the lid body is formed. Even if the surface area of the transparent body 10 is larger than the cross-sectional area of the outlet hole 8, it is limited to the cross-sectional area of the outlet hole 8, and the range that can be seen through is narrow. Therefore, there was a problem that the range in which the inside of the outlet hole can be seen through the transparent body 10 was extremely narrow.

調和装置におけるリキツドタンクである。[Structure of the invention] (Means for solving the problem) The present invention for achieving the above object consists of a liquid tank body containing a refrigerant for a cooling cycle;
An air conditioner for an automobile, comprising a lid fixed to the liquid tank body and having an introduction hole and an outlet hole, and a transparent body that allows the inside of the outlet hole to be seen through is attached to the upper end of the outlet hole. In the liquid tank, the transparent body is shaped like a cone, and the transparent body is caulked to the lid through a sealing material through a large diameter hole provided at the upper end of the outlet hole so that the apex faces the outlet hole and the bottom surface is exposed to the outside. This is a liquid tank used in automotive air conditioners.

共通する部位には同一の符号を附してある。(Example) An example of the present invention shown in FIG. 3 will be described below. Note that FIG. 3 corresponds to FIG. 2 showing the lid of the liquid tank, and parts common to those in FIG. 2 are given the same reference numerals.
蓋体２の上端部には、これに形成された導出孔

る。 A large-diameter hole 11 is formed at the upper end of the lid 2 and communicates with the outlet hole 8 formed therein, and an O-ring 12 is fitted into the large-diameter hole 11 as a sealing material. A conical transparent body 13 is attached to the large diameter hole 11 with its apex 17 facing the outlet hole 8 and its bottom surface 14 exposed to the outside.

なつている。 The O-ring 12 comes into contact with the conical surface 15 located between the apex 17 and the bottom surface 14, and the conical surface 15 becomes an inner surface that passes through the outlet hole 8. The inside of the lead-out hole 8 that is penetrated by the surface 15 is displayed in an enlarged manner.

透明体１３を取付けると透明体１３を溶融するた
めの熱源が不要となる。 Therefore, since the area of the lead-out hole 8, which has a relatively small diameter, is displayed on the bottom surface 14, which has a larger diameter, the inside of the lead-out hole 8 is displayed more easily when the inside is viewed through the transparent body 13. Also, transparent body 1
3 is attached to the lid body 2 by plastically deforming a caulked portion 16 of a part of the lid body 2, and the transparent body 1
3 is not installed in a molten state, the conical surface 15 and bottom surface 14 are beautifully finished, and the inside can be easily seen from this point as well. Furthermore, when the transparent body 13 is attached using this method, a heat source for melting the transparent body 13 becomes unnecessary.
