[Detailed Description of the Invention] This relates to a cap device for a gasoline tank for an automobile that is installed after being installed. Conventionally, in this type of cap device, as the gasoline in the tank is consumed, the inside of the tank is closed. This creates a vacuum state, which may deform the tank or prevent the simultaneous operation of the cap body screwed into the refueling tank. Therefore, a negative pressure valve is installed in the cap body to ensure that the tank is constantly maintained. It is adjusted to keep the air pressure constant.

たために負Hーバルブがギヤ7グ ルブの破損が多くなり、これを防止するためにキャップ
本体を長くして、負圧バルブがギヤ。
In the conventional molding of the cap body, the valve seat that fixes the negative pressure valve was formed approximately in the middle of the gear body, so the gear 7 groove of the negative H-valve was often damaged, and in order to prevent this. The cap body is lengthened and the negative pressure valve is geared.

If the cap body is made longer like this, the number of turns of the screws formed on the outside of the cap body will also increase, so attach such a cap body to the fuel filler port. There is a drawback that the cap body cannot be quickly attached or detached because many rotational operations are required when attaching or detaching the cap body.

In such a screw-in type cap body, the effective number of screws when installed is one turn or one and a half turns, and if at least one turn of screws is formed in the cap, the cap body will not be lubricated. There will be no departure.

The present invention has been made with attention to these points, and its objectives are to shorten the length of the cap body, reduce the number of screws, and further expose the negative pressure valve from the cap body. The goal is to avoid doing so.

以F1本発明の一実施例を図面と共に説明する。An embodiment of the F1 invention will be described below with reference to the drawings.

Further, the cap device A for a gasoline tank has a cap body 10 made of iron, in which a flange 11 is formed on two parts J and a screw 12 is formed on one outer part 3. This gasoline tank cap device A has a ratchet part 2 disposed on the upper part of a cap body 10 and a handle cap 1 that covers the upper part of the cap body 1o. 15, the cap body 10 is engaged with a circumferential groove 16 provided in the flanges 11 of the cap body 10. The ratchet portion 2 and the bottom surface of the dollar cap 1 constitute a torque regulating device using resin elasticity, but this configuration is well known and will not be described in detail.

Since the screw 12 on the outer part 3 of the cap body IO forms one turn, the thread from the flange 11 to the cap body 10
The negative pressure valve (2) is press-fitted inside the cap body 10 so that it is not exposed to the outside, but the valve seat 17 that supports the negative pressure valve (V) is placed in the radial direction of the flange 11 in approximately the same direction as the bottom surface. It is formed integrally with the cap body 10 on the inside. .

An air passage hole 18 is provided in the center of the valve seat 17.

In this way, in the present invention, by forming the valve seat 17 on the same -s17 plane as the flange 11, not only the strength of the cap during an impact is increased, but also the number of screws is small, making the cap smaller and easier to attach and detach. This has the effect that it can be done quickly.
