Description

【０００１】
【発明の属する技術分野】
本発明はスクーター型車両の燃料装置に関する。
【０００２】
【従来の技術】
スクーター型車両の燃料装置には、例えば、実公平８−１１９４号公報「スクータ型車両の燃料装置」に示されたものがある。このスクータ型車両の燃料装置は、同公報の第１図によれば、ヘルメットボックス２２（符号は公報記載のものを流用する。以下同じ。）の前部が隔壁部材４６に沿って下方まで延び、燃料ポンプ４２（第４図）とエンジン１５との間を遮っているので、エンジン１５から放熱される熱がこのヘルメットボックス２２によって遮断され、燃料ポンプ４２をエンジン１５に近づけることができ、配管を短くしてコンパクト化を図ることができるというものである。
【０００３】
また、このスクーター型車両の燃料装置は、ヘルメットボックス２２が上部に位置する構造の場合、ヘルメットボックス２２が遮熱材として作用しないので、遮熱部材であるクロスプレート４８（第６図）やクロスプレート４９（第７図）を用いて熱を遮断するというものである。
【０００４】
【発明が解決しようとする課題】
しかし、ヘルメットボックス２２のように箱の底を下方に延ばし、遮熱部を一体に設けると、形状が複雑になり、ヘルメットボックスは成形し難くなる。
また、上記のクロスプレート４８，４９のような遮熱板の場合、クロスプレートを他の部品と一体に成形することは難かしい。例えば、他の部品を基準に金型を開閉すると、クロスプレートが干渉するといったことが起きる。
【０００５】
そこで、本発明の目的は、遮熱板と他の部品を一体に成形することができ、遮熱板の組付けが容易なスクーター型車両の燃料装置を提供することにある。
【０００６】
【課題を解決するための手段】
上記目的を達成するために請求項１では、シートの下方にエンジンを配置し、このエンジンの前方に足載せのフロアを設け、このフロアの下方にアンダーカバーを設け、これらのアンダーカバーとフロアとの間に燃料ポンプを配置するとともに、この燃料ポンプとエンジンとの間に遮熱板を配置したスクーター型車両において、遮熱板は、アンダーカバーに折曲げ可能な折曲げ部を介して一体形成するとともに、折曲げ部で折曲げることで燃料ポンプを保護するようにしたものであることを特徴とする。
【０００７】
アンダーカバーと遮熱板との間に折曲げ部を設けて、これらのアンダーカバーと遮熱板とを一体で成形可能なように金型に各々のキャビティを展開し、遮熱板とアンダーカバーを一体に成形する。
また、遮熱板はアンダーカバーに折曲げ可能な折曲げ部を介して一体形成するとともに、折曲げ部で折曲げることで燃料ポンプを保護するようにしたものなので、遮熱板の組付けに手間がかからない。
請求項２では、遮熱板は、折曲げ部に連続するように設けた掛止爪を備え、アンダーカバーは、掛止爪を掛けるための掛止孔を有し、遮熱板を折り曲げたあとで掛止孔に掛止爪を係合させるので、遮熱板の組付けは容易になる。
請求項３では、遮熱板は、折曲げ部に連続するように設けた掛止爪と、掛止爪の上方に形成した遮熱部を備え、アンダーカバーの掛止孔に掛止爪を係合したときに、燃料ポンプの上部及びエンジン側へ向いている側部を遮熱部が覆うので、燃料ポンプを保護することができる。
請求項４では、遮熱板は、燃料ポンプの上部及びエンジン側へ向いている側部を覆うとともに、平面視で右側に配置されている燃料ポンプの外側の端部から、燃料ポンプに接続して左側に配置されている燃料フィルターの外側の端部までの幅と、遮熱板の左右の端部までの幅とがほぼ一致しているので、燃料装置を保護することができる。
請求項５では、アンダーカバーは、一端側の車幅方向中央に開口部を備え、折曲げ部は、開口部の両側に連ねて一端側に成形されているので、成形不良を防止し、一体に成形することができる。

In addition, the fuel pump is protected by being bent at the bent portion.
[0007]
A bent portion is provided between the under cover and the heat shield plate, and each cavity is developed in the mold so that the under cover and the heat shield plate can be integrally molded. Are molded in one piece.
In addition, the heat shield is formed integrally with the under cover via a foldable part that can be bent, and the fuel pump is protected by folding at the fold. It does not take time and effort.
In claim 2, the heat shield plate includes a latching claw provided to be continuous with the bent portion, and the under cover has a latch hole for hanging the latch claw, and the heat shield plate is bent. Since the latching claw is engaged with the latching hole later, the heat shield plate can be easily assembled.
According to a third aspect of the present invention, the heat shield plate includes a latching claw provided so as to be continuous with the bent part, and a heat shield part formed above the latching claw, and the latching claw is provided in the latching hole of the under cover. When engaged , the heat shield covers the upper part of the fuel pump and the side part facing the engine side, so that the fuel pump can be protected.
In claim 4, the heat shield plate covers the upper portion of the fuel pump and the side portion facing the engine side, and is connected to the fuel pump from the outer end portion of the fuel pump arranged on the right side in plan view. Therefore, the width to the outer end of the fuel filter disposed on the left side and the width to the left and right ends of the heat shield plate are substantially the same, so that the fuel device can be protected.
In claim 5, since the under cover includes an opening at the center in the vehicle width direction on one end side, and the bent portion is formed on one end side so as to be connected to both sides of the opening , Can be molded.
