つている。<Prior art and its problems> As shown in FIG. 2, there is a thin-walled pipe-like filler tube 4 provided on the fuel tank 1 side, and a thin-walled pipe-like filler neck 2 (hereinafter referred to as Filler tubes (referred to as filler tubes) are generally connected by a rubber hose 5, as shown in FIG. By binding the outer periphery of the tip with a hose band 7, the rubber hose 5 is prevented from coming off.
しかし、この構造であると、車体の衝突時など
においてフイラーチユーブ２，４とゴムホース５
間に大きな衝撃が加わると、同図に想像線で示す
ようにゴムホース５が変形してバルジ６の開口縁
に衝突し、鋭利な縁部により切れてしまうおそれ
があつた。 However, with this structure, the filler tubes 2 and 4 and the rubber hose 5 are
If a large impact is applied between them, the rubber hose 5 will be deformed and collide with the opening edge of the bulge 6, as shown by the imaginary line in the figure, and there is a risk that it will be cut by the sharp edge.
このため、従来では第４図に示すように開口縁
内周部に止壁６ａを形成しているが、この構造で
あると燃料の流れが止壁６ａによつて妨げられ、
また止壁６ａとバルジ６内周間で乱流が発生する
ため、燃料注入時の流通抵抗が大きくなる欠点が
あつた。 For this reason, conventionally, a stop wall 6a is formed on the inner periphery of the opening edge as shown in FIG. 4, but with this structure, the flow of fuel is obstructed by the stop wall 6a.
Further, since turbulent flow occurs between the stop wall 6a and the inner periphery of the bulge 6, there is a drawback that flow resistance increases during fuel injection.
《考案の目的》
この考案は、ゴムホースの切れを防止すると同
時に燃料の流通抵抗を小さくすることを目的とす
る。<Purpose of the invention> The purpose of this invention is to prevent the rubber hose from breaking and at the same time reduce the flow resistance of the fuel.

成することを特徴とする。<<Structure of the invention>> In order to achieve the above object, this invention forms a bulge to prevent the rubber hose from coming off on the outer periphery of the rubber hose joint end of the filler tube, and the opening edge of the bulge is folded inward, and the folded part is It is characterized by forming a streamlined surface that is substantially continuous with the inner circumferential wall of the filler tube.
《実施例の説明》
以下、この考案の一実施例を図面を用いて詳細
に説明する。<<Description of Embodiment>> Hereinafter, one embodiment of this invention will be described in detail using the drawings.
第１図はこの考案に係るフイラーチユーブとゴ
ムホースとの接合端を示す断面図である。 FIG. 1 is a sectional view showing the joint end of the filler tube and rubber hose according to this invention.

ことによりゴムホース１４の抜け止めを行つてい
る。 In the figure, mountain-shaped bulges 16, 18 are formed at the joint ends of the filler tubes 10, 12, which communicate with the fuel tank side and the fuel filler port side, with the rubber hose 14. The rubber hose 14 is prevented from coming off by fitting over the mountain-shaped portion and binding the hose band 20 around the outer periphery of the tip.
そして、各バルジ１６，１８の開口縁は内側に
折曲げられ、この折返し部２２の折返し縁をバル
ジ１６，１８の内側の山形状基部に隙間なく接触
させている。 The opening edge of each bulge 16, 18 is bent inward, and the folded edge of the folded portion 22 is brought into contact with the chevron-shaped base inside the bulge 16, 18 without a gap.
この結果、各フイラーチユーブ１０，１２の内
周部は折返し部２２に連続した形状となる。な
お、この折返し加工は周知の絞り加工により行う
ことができる。 As a result, the inner peripheral portion of each filler tube 10, 12 has a shape continuous with the folded portion 22. Note that this folding process can be performed by a well-known drawing process.
《考案の効果》
