【考案の詳細な説明】
本案は自動二輪車に用いられる合成樹脂製燃料タンクに
対するコック取付装置に関する。[Detailed Description of the Invention] The present invention relates to a cock attachment device for a synthetic resin fuel tank used in a motorcycle.
従来、この種のコック取付装置は第１図に示すように合
成樹脂製燃料タンク１の下面１ａに金属製コック２の取
付座２ａを当て、その取付座２ａの穴に通した一対のボ
ルト４，４を、燃料タンク１に一体にモールド成形され
たナツト５，５にねじ込んで取付は固定している。Conventionally, this type of cock mounting device, as shown in Fig. 1, has a mounting seat 2a of a metal cock 2 placed on the lower surface 1a of a synthetic resin fuel tank 1, and a pair of bolts 4 passed through holes in the mounting seat 2a. , 4 are screwed into nuts 5, 5 that are integrally molded into the fuel tank 1 to fix the installation.
ところが、合成樹脂製燃料タンク１はガソリンの浸漬の
ために膨潤したり、周囲温度の変化により変形して、上
記のボルト４，４間Ｔは数ｍｍ程度広がる。However, the synthetic resin fuel tank 1 swells due to immersion in gasoline or deforms due to changes in ambient temperature, and the distance T between the bolts 4 becomes wider by several millimeters.
このため、上記従来装置のようにボルト４．４間を取付
座２ａにより固定してしまうと、燃料タンクに不都合な
応力が発生したり、取り付はボルトがつかなくなる慣れ
がある等の不都合が存した。For this reason, if the bolts 4 and 4 are fixed by the mounting seat 2a as in the conventional device described above, there will be problems such as undesirable stress being generated on the fuel tank and the bolts becoming difficult to attach. It existed.
本案はこの不都合を解消することを目的とし、上記一対
のボルト４，４を結ぶ線Ｘ−Ｘ方向（第３図）つまり、
取付座２ａの燃料タンク１に対する取付中心から延びる
直線方向に取付座２ａのボルト通し穴３，３を長穴に形
成したものである。The purpose of this proposal is to eliminate this inconvenience, and the line XX direction (Fig. 3) connecting the pair of bolts 4, 4, that is,
The bolt through holes 3, 3 of the mounting seat 2a are formed into elongated holes extending in a straight line direction from the center of attachment of the mounting seat 2a to the fuel tank 1.
６は取付座２ａの上面に突出させたストレーナで、穴７
から燃料タンク１内に挿入される。6 is a strainer protruding from the upper surface of the mounting seat 2a, and the hole 7
It is inserted into the fuel tank 1 from below.
８はストレーナ基部６ａにはめたＯリングで、取付座２
ａを燃料タンク１の下面から０．１〜０．２ｍｍ程度浮
かせて収付けるためと、ガソリンのシール作用のために
設けられている。8 is an O-ring fitted into the strainer base 6a, and the mounting seat 2
The fuel tank 1 is provided in order to store the fuel tank 1 floating by about 0.1 to 0.2 mm from the lower surface of the fuel tank 1, and to seal the gasoline.
９は長穴３，３にはめたカラーで、その先端が長穴３，
３より突出するように上記取付座２ａの厚みより長くな
っている。9 is a collar fitted into the long holes 3, 3, and its tip is inserted into the long holes 3, 3.
3 and is longer than the thickness of the mounting seat 2a.
１０はコック２の切換レバーである。燃料タンク１の下
面１ａにコック２を取付けるために、カラー９に通した
ボルト４をナツト１５に螺合すると、カラー９の先端が
ナツト５の端面に当接してボルト４の締付は力を受ける
ため、この締付は力は取付座２ａに加わることがないと
ともに燃料タンク１と取付座２ａ間の隙間１１を確実に
確保することができる。10 is a switching lever for the cock 2. In order to attach the cock 2 to the lower surface 1a of the fuel tank 1, when the bolt 4 passed through the collar 9 is screwed into the nut 15, the tip of the collar 9 comes into contact with the end surface of the nut 5, and the tightening of the bolt 4 requires a force. Therefore, in this tightening, no force is applied to the mounting seat 2a, and the gap 11 between the fuel tank 1 and the mounting seat 2a can be reliably secured.
本考案は上記の構成であるから、燃料タンク１は膨潤又
は変形するとき、取付座２ａに対して無接触状態で横方
向に移動する。Since the present invention has the above configuration, when the fuel tank 1 swells or deforms, it moves laterally with respect to the mounting seat 2a without contacting it.
このため、ボルト４．４は長穴３，３に沿って矢印方向
に逃げ移動し、燃料タンクの該ボルト間の広がり変形が
円滑に行われる。Therefore, the bolts 4.4 escape along the elongated holes 3, 3 in the direction of the arrow, and the fuel tank is smoothly expanded and deformed between the bolts.
従って、燃料タンクには応力が生ずることがなく前記の
不都合がよく解消され、合成樹脂製燃料タンクに対する
コック取付装置として極めて有効である。Therefore, stress is not generated in the fuel tank, and the above-mentioned disadvantages are well solved, making the device extremely effective as a cock attachment device for a synthetic resin fuel tank.
なお、図示例はコック２を一対のボルト４，４で燃料タ
ンク１に取付けたものであるが、Ｘ−Ｘ方向と直交する
位置にもボルトを設ける場合は、そのボルトの通し穴を
Ｘ−Ｘ方向と直交する方向に長穴とするものである。In the illustrated example, the cock 2 is attached to the fuel tank 1 with a pair of bolts 4, 4, but if a bolt is also provided at a position perpendicular to the X-X direction, the through hole of the bolt should be The hole is elongated in a direction perpendicular to the X direction.
