ンク１内のエアプリーズ作用を行えるようにしてちる。A level gauge 7 is installed vertically on the lower surface. A buffer rubber 8 is attached to the middle of the level gauge 7. When the filler cap 4 is attached to the filler boat 2, the opening 3a of the bottom wall of the air chamber 3 rf'! This is to prevent an oil fan from occurring even if the hydraulic oil moves due to blockage with the buffer rubber 8. In addition, this air chamber 3
To suppress the electricity, an air bleed pipe 9 is provided protruding from the upper space 8 in the hydraulic oil tank 1 and the filler character 160 ventilation part 5.
Air bleed pipe 9. It communicates with the air chamber 3 via the air chamber 3, thereby making it possible to perform an air pleat action within the hydraulic oil tank 1 as shown by the arrow in FIG.

When the hydraulic oil in the tank 1 is used for night shifts, the air bleed pipe 9 is covered with hydraulic oil, and the hydraulic oil enters the air chamber 3 through this pipe 9, which gradually causes the cap to close. Through 4, the outside / ＼ is drowned, and 5 again.
パイプ９が詰まって、ブリーズ機能が十分に発揮できな
いという不具合があった。There was a problem in that the pipe 9 was clogged and the breeze function could not be fully utilized.

点がある。The embodiment shown in FIG. 4 is an example in which the present invention is applied to a hydraulic oil tank having an air chamber 3 under a filler boat 2, in which a boat 16 is protruded from the wall of the air chamber 311111.
The @ end of the oT tube 13 is connected to this boat 16 to communicate the air section 12 with the cap ventilation section 5 via the air chamber 3. Additionally, there is an advantage that the present invention can be applied to an existing conventional hydraulic oil tank by only slightly changing the air bleed pipe 9.

とｙｓ５実用上多大な効果を有する。In the above 15, the trap of the present invention is that even if the hydraulic oil level in the hydraulic oil tank fluctuates drastically, the float follows the oil level fluctuation well, resulting in leakage of hydraulic oil from around the filler boat. It would be possible to perform the air pleat action in the tank without any problems, and if the reliability and quality could be further improved, it would have a great practical effect on the YS5.
