して外れ易い等の不都合を有していた。Conventionally, in this type of tank, a gas-liquid separation chamber C is formed in the upper part of the tank body a by a separator b, as shown in the first diagram.
A type is known in which the interior is connected to an external canister or the like through a conduit e having a relief valve d, but in this case, the iron separation chamber C is connected to the outside of the tank body a as shown in the figure. Generally, it is mounted on a plate, and in such a case, the outer plate must be processed to attach it, which is difficult and spoils the appearance of the tank, and furthermore, the valve d and the conduit This has disadvantages such as the joint part with e is exposed to the outside and easily comes off.

ことを特徴とする。The purpose of the present invention is to obtain a device that does not have such inconveniences.The purpose of the present invention is to form a gas-liquid separation chamber 3 with a separator 2 in the upper part of a closed tank body 1.
In a relief valve device for a fuel tank that communicates with an external canister via a conduit 5 having an IJ valve 4, a gas-liquid separation chamber 3 formed by the separator 2 is raised in the center of the bottom plate 1b of the tank body 1. At the same time, the relief valve 4 is provided in the gas-liquid separation chamber 3, and the connection port 4e of the valve 4 is passed through the raised part 1C and connected to the bottom plate 1b by the raised top part 1C. It is characterized by having a protruding opening in the formed recess.

セパレーター２とに一体的に結着されるようにした。In the illustrated tank body 1, the tank body 1 consists of an upper outer plate 1a and a lower bottom plate 1b having a raised top 1C in the center, and the separator 2 has a frame-like shape and overlaps the raised top 1C. The valve 4 is integrally connected to the raised top portion 1C and the separator 2 at the lower end of the outer valve housing 4a.

部１Ｃを貫通して下方にのびる接続口４ｅを備える。The valve 4 is provided with a valve body 4C located within the valve housing 4a and resiliently repelled upward by a spring 4b, which is opposed to a valve hole 4d on its upper surface, and has a raised top 1C extending through its lower side. A connection port 4e extending downward is provided.

の効果を有する。In this way, according to the present invention, the gas-liquid separation chamber 3 formed by the separator 2 is fixedly attached to the ridged top 1C raised in the center of the bottom plate 1b of the tank body 1. Unlike the tank outer plate, the appearance of the tank bottom plate 1b to be attached is not important, so the attachment part is easier to process and the attachment part is easier to process than when the gas-liquid separation chamber 3 is attached to the tank outer plate. Despite the tank bottom plate 1b, since it is mounted on the raised top part 1C of the tank bottom plate 1b, the mounting height can be maintained sufficiently. Top 1
Since the conduit is penetrated through C and is opened in a protruding manner into the recess formed in the bottom plate 1b by the raised top, it has the effect of facilitating the connection of the conduit.
