ルキャップである。Therefore, the present invention has a concave partition frame 7 which has a stepped valve seat 11 in a hollow body 1 consisting of two upper and lower members 1a and lb, which is applied to the spout of a tank a, and a concave partition frame 7 fixed to the upper part of the frame. A fixed plate 9 with air holes 8 is attached, and two large and small coil springs 2 and 3 are applied vertically oppositely between the partition frame 7 and the fixed plate 9, and the flexible valve plate 4 is moved vertically at the opposing position. The flexible valve plate 4 is interposed between the spring receiving plates 5 and 6 of the partition frame 7.
A peripheral contact portion 12 that contacts and separates from the valve seat 11 formed in A valve seat 15 is provided on the fixed plate 9 to protrude downward from the fixed plate 9, and the valve seat 15 is formed around the small-hole circulation valve 14 and closes the small-hole outdoor air circulation valve 14.
A communication hole 2 of the partition frame 7 is provided in the pipe portion 21 protruding from the through hole 10.
2 are fitted together, and the hollow main body 1 is further provided with a backing 16 that is crimped onto the spout, and a locking plate 17 for the spout, and an external ventilation hole 23 that communicates with the ventilation hole 8 is formed in the main body 1. It's a cap.

蓋の機能を果す。Since the present invention consists of the above configuration, the tank a
It can be easily installed by elastically locking the locking plate 17 to the oil filler port, and under normal conditions, the valve plate 4 is closed in contact with the valve seat 11 as shown in FIG. is press-fitted to the valve seat 15, so that air does not flow between the vent hole 8 and the through hole 10, and it functions as a lid.
そしてタンク内が高圧になったときは、第３図に示すよ
うに内圧で上位のコイルばね２に抗して弁板４は押上げ
られ気化ガスは弁板４と弁座１１の間を経て、通気孔８
、同２３より外部に排気される。When the pressure inside the tank becomes high, the internal pressure pushes up the valve plate 4 against the upper coil spring 2, and the vaporized gas passes between the valve plate 4 and the valve seat 11. , ventilation hole 8
, 23 is exhausted to the outside.
（矢印イ参照）そして圧力が低くなればコイルばね２の
作用で第２図に示す閉塞状態に戻る。(See arrow A) When the pressure becomes low, the action of the coil spring 2 returns to the closed state shown in FIG.

入することができる。Next, when the inside of the tank becomes negative pressure, the flexible valve plate 4 is bent and the outside air circulation small hole valve 14 is opened from the valve seat 15 to allow outside air to flow through the vent hole 8 as shown by the arrow in FIG. The air can be sucked into the tank through the small hole valve 14 and the through hole 10 in the center of the valve plate.

1, by fitting the communication hole 22 of the partition frame 7, the partition frame 7 and the valve mechanism incorporated therein can be correctly attached to the main body 1, and the valve plate 4 is fitted with the small hole valve in the center. 14
is fitted into the center ring part 13 of the lower spring receiving plate 6, and the outer periphery is a free edge, so the vertical movement of the valve plate 4 is performed smoothly by the automatic expansion and contraction of the edge. There is a remarkable effect that even if the plate 4 swells, it will not be improperly deformed.
ゆえにタンク内の異常圧によっても安全で危険性の全く
ないキャップを得ることができる。Therefore, it is possible to obtain a cap that is safe and completely free from danger even under abnormal pressure inside the tank.
