Description

本発明は、燃料タンクの給油口に取りつけられて、ジェリー缶等の燃料携行缶から燃料タンクに給油する際に使用される給油漏斗に関するものである。   The present invention relates to a fueling funnel that is attached to a fueling port of a fuel tank and used when fueling a fuel tank from a fuel carrying can such as a jelly can.

従来、走行作業機としてバックホーがあり、このバックホーにあっては、エンジン、ラ
ジエータ等を収容するボンネット内に燃料タンクが収容され、この燃料タンクの給油口は、ボンネット側面に配置される場合、ボンネットの外面から、はみ出さないように、ボンネットに凹みを設け、この凹み内に給油口の開口端部側が配置されるようになっている。
前記バックホーの燃料タンクにジェリー缶などの給油ノズルがない燃料携行缶から給油する場合、そのままで給油するのは困難である。 Conventionally, there is a backhoe as a traveling work machine. In this backhoe, when a fuel tank is accommodated in a bonnet that accommodates an engine, a radiator, etc., and a fuel filler port of this fuel tank is disposed on the side of the bonnet, A recess is provided in the bonnet so as not to protrude from the outer surface, and the opening end side of the fuel filler opening is disposed in the recess.
When refueling from a fuel carrying can that does not have a refueling nozzle such as a jelly can in the fuel tank of the backhoe, it is difficult to refuel as it is.

そこで、このような場合、口径の小さい注入口から液体を投入する際に使用される漏斗を使うことが考えられる。
該漏斗は、円錐状の上部の漏斗本体と、漏斗本体の底部に連結された下部の案内管とから構成されている（特許文献１参照）。 Therefore, in such a case, it is conceivable to use a funnel that is used when liquid is poured from an inlet having a small diameter.
The funnel is composed of a conical upper funnel body and a lower guide tube connected to the bottom of the funnel body (see Patent Document 1).

実開昭６３−１９７８９８号公報Japanese Utility Model Publication No. 63-197898

給油口がボンネット側面に設けられる場合、該給油口は斜め上方に開口する傾斜状に設けられる。
一方、漏斗は、漏斗本体の投入口の中心線と案内管の軸線とが一致するように形成され、また、案内管は注入口に差し込まれるだけである。
漏斗本体の投入口の中心線と案内管の軸線とが一致するように形成されていると、斜め上方に開口する傾斜状の給油口に漏斗の案内管を差し込んだ場合、給油口の開口方向と漏斗本体の投入口の開口方向とが一致し、給油口の傾斜角度が小さい（例えば、４５°以下）と、漏斗の投入口から給油がし難いという問題がある。 When the fuel filler port is provided on the side surface of the bonnet, the fuel filler port is provided in an inclined shape that opens obliquely upward.
On the other hand, the funnel is formed such that the center line of the inlet of the funnel body and the axis of the guide tube coincide with each other, and the guide tube is only inserted into the inlet.
If the center line of the funnel inlet and the axis of the guide tube are aligned, when the funnel guide tube is inserted into the slanted filler port that opens obliquely upward, the opening direction of the filler port When the opening direction of the inlet of the funnel body coincides and the inclination angle of the oil filler port is small (for example, 45 ° or less), there is a problem that it is difficult to supply oil from the inlet of the funnel.

そこで、漏斗の案内管を上向き傾斜状の給油口に差し込んだ状態で投入口が給油口の開口方向よりも上側を向くように、漏斗を形成することが考えられる。
しかしながら、燃料携行缶を持ち上げて燃料を漏斗に投入する場合、重量のある燃料携行缶を持ちながら漏斗に燃料を投入するのは大変であることから、漏斗の投入口に燃料携行缶をのせることが考えられる。 Therefore, it is conceivable to form the funnel so that the inlet port faces upward from the opening direction of the fuel filler port in a state where the guide tube of the funnel is inserted into the upwardly inclined fuel filler port.
However, when the fuel carrying can is lifted and the fuel is put into the funnel, it is difficult to put the fuel into the funnel while holding the heavy fuel carrying can, so put the fuel carrying can at the inlet of the funnel It is possible.

このような場合、傾斜状の給油口に案内管が差し込まれているだけであると、漏斗の投入口が横又は下を向くように、案内管が回動してしまう場合がある。
そこで、本発明は、前記問題点に鑑み、斜め上方に向けて開口する傾斜状の給油口に対して、燃料携行缶によって給油する場合の給油の容易性を考慮した給油漏斗を提供することを課題とする。 In such a case, if the guide tube is merely inserted into the inclined fuel filler port, the guide tube may rotate so that the charging port of the funnel faces sideways or downward.
Therefore, in view of the above problems, the present invention provides a refueling funnel that takes into account the ease of refueling when refueling with a fuel carrying can with respect to an inclined refueling port that opens obliquely upward. Let it be an issue.

前記技術的課題を解決するために本発明が講じた技術的手段は、請求項１に係る発明によれば、斜め上方に向けて開口する傾斜状の給油口に取りつけられる給油漏斗であって、
前記給油口を施蓋する給油キャップを取り付ける取付部に回り止めされて取り付けられ且つ該取付状態で燃料投入口が給油口の開口方向よりも上側を向くように構成されており、

The fuel input port at stop is mounted and the mounted state around the fuel supply port to the mounting portion for mounting the fuel supply cap to lidding is configured so as to face above the opening direction of the filler opening,
A straight tubular guide tube made of a hard material attached to the fuel filler port, and a funnel body made of an elastic material having the fuel inlet, and a guide tube shaft formed in a tube insertion groove formed in the funnel body The funnel body is connected to the guide tube by inserting the upper side in the center direction, and the insertion margin of the guide tube with respect to the tube insertion groove is larger on the lower side than the upper side in the radial direction of the guide tube. To do.

請求項２に係る発明によれば、案内管の下端側を給油口に差し込んで所定角度周方向に回動させることにより、案内管が回り止めされ且つ燃料投入口が給油口の開口方向よりも上側を向くように取りつけられるよう構成されていることを特徴とする。 According to the second aspect of the present invention , the guide tube is prevented from rotating by inserting the lower end side of the guide tube into the fuel filler port and rotating in the circumferential direction by a predetermined angle, and the fuel input port is located more than the opening direction of the fuel filler port. It is configured to be mounted so as to face upward .

本発明によれば以下の効果を奏する。
請求項１に係る発明によれば、給油漏斗は、給油口を施蓋する給油キャップを取り付ける取付部に回り止めされて取り付けられるので、重量のある燃料携行缶をのせても保持す
ることができて、給油を容易に行うことができ、且つ斜め上方に向けて開口する給油口に取りつけても給油口に取り付けられた状態で燃料投入口が給油口の開口方向よりも上側を向くのでノズルのない燃料携行缶でも給油が容易に行える。 The present invention has the following effects.
According to the first aspect of the present invention, the refueling funnel is attached to the attachment portion to which the refueling cap that covers the refueling port is attached, so that it can be held even if a heavy fuel carrying can is placed on it. Therefore, even if it is attached to the fuel inlet that opens obliquely upward, the fuel input port faces upward from the opening direction of the fuel inlet, so that the nozzle Refueling can be done easily even with no fuel carrying can.

さらに、漏斗本体の管挿入溝に対する案内管の差込み代が、案内管の径方向上部側よりも下部側が大とされているので、管挿入溝に案内管を挿入することで漏斗本体と案内管との周方向の位置決めが行われる。また、燃料携行缶をのせても、案内管の管挿入溝への差込み部分の下部側で燃料携行缶の重量を受けるので、燃料携行缶を十分に保持できる。
請求項２に係る発明によれば、案内管の下端側を給油口に差し込んで所定角度周方向に回動させることにより、案内管が回り止めされ且つ燃料投入口が給油口の開口方向よりも上側を向く状態に取りつけられるので、給油漏斗の取付が容易に行える。 Furthermore, the insertion allowance of the guide tube with respect to the tube insertion groove of the funnel body is larger on the lower side than the radial upper side of the guide tube. By inserting the guide tube into the tube insertion groove, the funnel body and the guide tube are inserted. Positioning in the circumferential direction is performed. Even when the fuel carrying can is placed, the weight of the fuel carrying can is received on the lower side of the insertion portion of the guide tube into the tube insertion groove, so that the fuel carrying can can be sufficiently held.
According to the second aspect of the present invention, the guide tube is prevented from rotating by inserting the lower end side of the guide tube into the fuel filler port and rotating in the circumferential direction by a predetermined angle, and the fuel input port is located more than the opening direction of the fuel filler port. Since it is attached so that it faces upward, the oiling funnel can be easily attached.

燃料携行缶１６から燃料タンクに給油する場合、燃料が入った重い燃料携行缶１６を高い位置まで持ち上げずに給油することができるように、給油口１５はできるだけ低い位置に設けるのがよい。
前記給油口１５は、図６に示すように、円筒状とされて斜め上方に向けて（本実施形態では、左右方向外方に行くに従って上方に移行する傾斜方向に）開口状とされて傾斜状とされており、図１１に示す給油キャップ１７によって施蓋されている。 When fuel is supplied from the fuel carrying can 16 to the fuel tank, the fuel filler port 15 is preferably provided at a position as low as possible so that the heavy fuel carrying can 16 containing the fuel can be supplied without being lifted to a high position.
As shown in FIG. 6, the fuel filler port 15 is formed in a cylindrical shape and is inclined obliquely upward (in the present embodiment, in an inclined direction that moves upward as it goes outward in the left-right direction). And is covered with a fueling cap 17 shown in FIG.

給油口１５の開口側縁部には、周方向全周にわたって内側に折り返されてなる折返し部１８が形成され、この折返し部１８には、図７、図８に示すように、一対の切欠部１９が給油口１５の径方向で対向する位置に形成されている。
前記折返し部１８の折返し側の端面には、給油口１５の軸心Ｘ方向内方に突出させることにより形成された接当部２０が各切欠部１９の近傍に設けられており、該一対の接当部２０は給油口１５の径方向で対向する位置に設けられている。 On the opening side edge of the fuel filler opening 15 is formed a folded portion 18 that is folded inward over the entire circumference in the circumferential direction. The folded portion 18 has a pair of notches as shown in FIGS. 19 is formed in the position which opposes in the radial direction of the fuel filler opening 15.
A contact portion 20 formed by projecting inward in the axial center X direction of the oil filler port 15 is provided in the vicinity of each notch portion 19 on the end surface of the folded portion 18 on the folded side. The contact portion 20 is provided at a position facing the oil supply port 15 in the radial direction.

具体的には、接当部２０は、各切欠部１９の給油口１５周方向一方側Ｆ１に隣接して設
けられている。
また、折返し部１８の折返し側の端面には、各接当部２０の給油口１５周方向一方側Ｆ１に隣接して係合凹部２１が設けられている。
また、折返し部１８の折返し側の端面には、各切欠部１９の給油口１５周方向他方側Ｆ２に隣接して傾斜ガイド面２２が設けられている。該傾斜ガイド面２２は、切欠部１９から給油口１５周方向他方側Ｆ２に行くに従って下方に移行する傾斜状に形成されている。 Specifically, the contact portion 20 is provided adjacent to one side F <b> 1 in the circumferential direction of the filler opening 15 of each notch portion 19.
Further, an engagement recess 21 is provided on an end surface of the turn-up portion 18 on the turn-back side, adjacent to the one side F1 in the circumferential direction of the oil supply port 15 of each contact portion 20.
Further, an inclined guide surface 22 is provided on an end surface of the folded portion 18 on the folded side, adjacent to the other side F <b> 2 in the circumferential direction of the oil supply port 15 of each notch portion 19. The inclined guide surface 22 is formed in an inclined shape that moves downward from the notch portion 19 toward the other side F2 in the circumferential direction of the fuel filler port 15.

また、折返し部１８の折返し側の端面の、傾斜ガイド面２２と係合凹部２１との間は、給油口１５の軸心に直交する平坦面とされた平坦ガイド面２３とされている。
前記接当部２０、係合凹部２１、平坦ガイド面２３、傾斜ガイド面２２は、切欠部１９間に、給油口１５周方向に順に形成されている。
なお、給油口１５内の奥部分には、給油口１５に挿入されるフィルタを受けるリング状のフィルタ受け２４が設けられている。 Further, a flat guide surface 23 that is a flat surface orthogonal to the axis of the fuel filler port 15 is formed between the inclined guide surface 22 and the engagement recess 21 on the end surface of the folded portion 18 on the folded side.
The contact portion 20, the engagement recess 21, the flat guide surface 23, and the inclined guide surface 22 are sequentially formed between the notches 19 in the circumferential direction of the fuel filler opening 15.
In addition, a ring-shaped filter receiver 24 that receives a filter inserted into the fuel filler port 15 is provided in the inner portion of the fuel filler port 15.

図１１に示すように、給油キャップ１７には、前記給油口１５の切欠部１９から挿入されて折返し部１８の折返し側の端面に係合する一対の係合片２６（被取付部）が径方向で対応する位置に形成されている。
係合片２６は上方に向けて凸となる円弧状に形成され、該係合片２６は、バネによって上方に付勢されている。また、該係合片２６は給油キャップ１７で給油口１５を施蓋する際に、切欠部１９から挿入可能とされている。 As shown in FIG. 11, the oil supply cap 17 has a pair of engagement pieces 26 (attached portions) that are inserted from the notches 19 of the oil supply port 15 and engage with the end surfaces on the turn-up side of the turn-up portion 18. It is formed at a position corresponding to the direction.
The engagement piece 26 is formed in an arc shape that is convex upward, and the engagement piece 26 is biased upward by a spring. The engaging piece 26 can be inserted from the notch 19 when the oil filler cap 17 is used to cover the oil filler port 15.

給油キャップ１７には、キーで操作可能なシリンダ錠が内蔵され、このシリンダ錠のキー操作によって係合片２６が給油口１５の周方向に回転操作可能とされている。
したがって、給油キャップ１７で給油口１５を施蓋し、図８に示すように、係合片２６を切欠部１９から給油口１５内に挿入し、該係合片２６をキー操作によって、図７、図８の矢示Ｅ方向に回転させると、係合片２６が傾斜ガイド面２２に接当すると共に該傾斜ガイド面２２上を摺動し、係合片２６がバネの付勢力に抗して引き下げられ、係合片２６が平坦ガイド面２３を経て係合凹部２１に至り、接当部２０に当たって回り止め及び抜け止めされ、これによって給油キャップ１７が給油口１５に取り付けられる。 A cylinder lock that can be operated with a key is built in the oil filler cap 17, and the engaging piece 26 can be rotated in the circumferential direction of the oil filler port 15 by the key operation of the cylinder lock.
Accordingly, the oil filler 15 is covered with the oil filler cap 17, and as shown in FIG. 8, the engaging piece 26 is inserted into the oil filler 15 from the notch 19, and the engaging piece 26 is operated by key operation as shown in FIG. 8, when the engagement piece 26 contacts the inclined guide surface 22 and slides on the inclined guide surface 22, the engagement piece 26 resists the biasing force of the spring. The engagement piece 26 reaches the engagement recess 21 via the flat guide surface 23 and is stopped against coming off and coming off against the contact portion 20, whereby the oil supply cap 17 is attached to the oil supply port 15.

前記折返し部１８によって、給油キャップ１７を取り付ける取付部が構成されている。
前記状態で、シリンダ錠からキーを引き抜くことにより、給油キャップ１７の把持ハンドル１７ａが空回りし、係合片２６を回して給油キャップ１７を給油口１５から取り外すことができないようになっている。
図１、図１０等において、２７は、燃料タンクの前記給油口１５に取りつけられて、燃料携行缶１６から燃料タンクに給油する際に使用される給油漏斗である。 An attachment portion for attaching the fuel filler cap 17 is constituted by the folded portion 18.
In this state, by pulling out the key from the cylinder lock, the grip handle 17a of the fuel cap 17 is idle, and the engagement piece 26 cannot be rotated to remove the fuel cap 17 from the fuel inlet 15.
In FIG. 1, FIG. 10, etc., 27 is a refueling funnel that is attached to the refueling port 15 of the fuel tank and is used when refueling from the fuel carrying can 16 to the fuel tank.

前述したように、給油口１５は、ボンネット１２側面の凹部１４内に位置していて、ボンネット１２側面からはみ出していないので、ノズルのない燃料携行缶１６によって給油するのが困難であるが、図１０（ａ）に示すように、前記給油漏斗２７を給油口１５に取り付けることにより、該給油漏斗２７の燃料投入口２８がボンネット１２の側面から側方に、はみ出すことにより、図１０（ｂ）に示すように、燃料携行缶１６によって容易に給油することができる。   As described above, the fuel filler port 15 is located in the recess 14 on the side surface of the bonnet 12 and does not protrude from the side surface of the bonnet 12, so that it is difficult to supply fuel by the fuel carrying can 16 without the nozzle. 10 (a), by attaching the refueling funnel 27 to the refueling port 15, the fuel input port 28 of the refueling funnel 27 protrudes laterally from the side surface of the bonnet 12, so that FIG. As shown, the fuel can can be easily supplied by the fuel carrying can 16.

図３に示すように、この給油漏斗２７は、上部の漏斗本体２９と、下部の案内管３０と、該案内管３０の下部に外嵌されたパッキン３１とから主構成されている。
漏斗本体２９は、上部のロート部３２と、下部の筒部３３とから構成され、ロート部３２と筒部３３とはゴム等の弾性材料によって一体形成されている。
ロート部３２は、お椀形に形成され、上端開口が口径の大きな（広口の）円形状の燃料投入口２８とされ、底部に燃料投入口２８より径小の円形の開口３４が形成されている。 As shown in FIG. 3, the oil supply funnel 27 is mainly composed of an upper funnel body 29, a lower guide tube 30, and a packing 31 that is externally fitted to the lower portion of the guide tube 30.
The funnel body 29 includes an upper funnel portion 32 and a lower cylindrical portion 33, and the funnel portion 32 and the cylindrical portion 33 are integrally formed of an elastic material such as rubber.
The funnel portion 32 is formed in a bowl shape, the upper end opening is a circular fuel inlet 28 having a large diameter (wide opening), and the circular opening 34 having a smaller diameter than the fuel inlet 28 is formed at the bottom. .

筒部３３は、円筒状に形成され、軸心Ｙ方向上端側がロート部３２の底部開口３４に連通し、軸心Ｙ方向下端は開口状とされている。
この筒部３３の軸心Ｙは、ロート部３２の中心線Ｚ（燃料投入口２８の中心（開口面中心）と底部開口３４の中心（開口面中心）とを結ぶ線）と所定角度をもって交差している。 The cylindrical portion 33 is formed in a cylindrical shape, the upper end side in the axial center Y direction communicates with the bottom opening 34 of the funnel portion 32, and the lower end in the axial center Y direction is open.
The axial center Y of the cylindrical portion 33 intersects the center line Z of the funnel portion 32 (a line connecting the center of the fuel inlet 28 (center of the opening surface) and the center of the bottom opening 34 (center of the opening surface)) with a predetermined angle. doing.

したがって、筒部３３はロート部３２の底面から斜め下方に延出されている。
また、筒部３３の下端開口の開口面は筒部３３の軸心Ｙに対して直交状とされており、該筒部３３は径方向Ｗ上部側に比べて径方向Ｗ下部側が軸心Ｙ方向に長く形成されている。
この筒部３３には、軸心Ｙ方向下端面から軸心Ｙ方向上方に向けて、管挿入溝３５が周方向全周にわたって形成されている。 Accordingly, the cylindrical portion 33 extends obliquely downward from the bottom surface of the funnel portion 32.
In addition, the opening surface of the lower end opening of the cylindrical portion 33 is orthogonal to the axial center Y of the cylindrical portion 33, and the cylindrical portion 33 has an axial center Y on the lower side in the radial direction W compared to the upper side in the radial direction W. It is long in the direction.
In the cylindrical portion 33, a tube insertion groove 35 is formed over the entire circumference in the circumferential direction from the lower end surface in the axial center Y direction upward in the axial center Y direction.

この管挿入溝３５は、筒部３３の軸心Ｙ方向下端から上端にかけて形成されており、筒部３３の径方向Ｗ下部側の溝深さが、筒部３３の径方向Ｗ上部側の溝深さよりも長く形成されている（筒部３３の径方向Ｗ上端から下端に行くに従って溝深さが漸次深くなるように形成されている）。
また、管挿入溝３５の溝奥面（溝底面）は、筒部３３の軸心Ｙに直交する面に形成されている。 The tube insertion groove 35 is formed from the lower end to the upper end of the cylindrical portion 33 in the axial center Y direction, and the groove depth on the lower side in the radial direction W of the cylindrical portion 33 is the groove on the upper side in the radial direction W of the cylindrical portion 33. It is formed longer than the depth (formed so that the groove depth gradually increases from the upper end to the lower end in the radial direction W of the cylindrical portion 33).
Further, the groove back surface (groove bottom surface) of the tube insertion groove 35 is formed on a surface orthogonal to the axis Y of the cylindrical portion 33.

案内管３０は、金属パイプ（又は硬質樹脂パイプ等の硬質材料）によって軸心Ｙ方両端が開口した直管状に形成され、該案内管３０の軸心Ｙ方向上端側がロート部３２の筒部３３に同心状に接続されている。この案内管３０の軸心Ｙ方向下端側には該下端から案内管３０の軸心Ｙ方向上方側に所定距離をおいてリング状のフランジ３６が外嵌されて固着されている。   The guide tube 30 is formed in a straight tube shape with both ends of the axial center Y opened by a metal pipe (or a hard material such as a hard resin pipe), and the upper end side of the guide tube 30 in the axial center Y direction is a cylindrical portion 33 of the funnel portion 32. Are concentrically connected. A ring-shaped flange 36 is externally fitted and fixed to the lower end side of the guide tube 30 in the axial center Y direction at a predetermined distance from the lower end to the upper side of the guide tube 30 in the axial center Y direction.

案内管３０の軸心Ｙ方向上端側は、図２、図３、図５に示すように、開口面が案内管３０の軸心Ｙに交差するように且つ径方向Ｗ下部側が上部側よりも軸心Ｙ方向上方側に突出するように形成されている。
また、案内管３０の軸心Ｙ方向上端側の端面は、全周にわたって案内管３０の軸心Ｙに直交する面に形成されている。 As shown in FIGS. 2, 3, and 5, the upper end side of the guide tube 30 in the axial center Y direction is such that the opening surface intersects the axial center Y of the guide tube 30 and the lower side in the radial direction W is higher than the upper side. It is formed so as to protrude upward in the axis Y direction.
Further, the end surface on the upper end side in the axis Y direction of the guide tube 30 is formed in a plane orthogonal to the axis Y of the guide tube 30 over the entire circumference.

案内管３０の軸心Ｙ方向上端側を筒部３３の管挿入溝３５に挿入することにより、案内管３０が漏斗本体２９の筒部３３に同心状に接続される。また、管挿入溝３５の溝奥面に案内管３０の軸心Ｙ方向上端側の端面が面接触する。
前記構成により、漏斗本体２９の管挿入溝３５に対する案内管３０の差込み代が、案内管３０の径方向Ｗ上部側よりも下部側が大とされている。 The guide tube 30 is concentrically connected to the tube portion 33 of the funnel body 29 by inserting the upper end side of the guide tube 30 in the axis Y direction into the tube insertion groove 35 of the tube portion 33. Further, the end surface of the guide tube 30 on the upper end side in the axial center Y direction is in surface contact with the groove inner surface of the tube insertion groove 35.
With the above-described configuration, the insertion allowance of the guide tube 30 with respect to the tube insertion groove 35 of the funnel body 29 is larger on the lower side than on the upper side in the radial direction W of the guide tube 30.

なお、漏斗本体２９の筒部３３の外面には、筒部３３の周方向全周にわたる突条部３７が軸心Ｙ方向一対形成されており、この一対の突条部３７間にバンドを設け、該バンドによって筒部３３と案内管３０とを締め付け固定することもできる。
案内管３０の軸心Ｙ方向下端側には、径方向Ｗ一対の切欠き溝３８が形成され且つ各切欠き溝３８から径方向Ｗ外方に突出する係合片３９（被取付部）が設けられている。 A pair of protrusions 37 extending in the circumferential direction of the cylindrical part 33 are formed on the outer surface of the cylindrical part 33 of the funnel body 29, and a band is provided between the pair of protruding protrusions 37. The cylindrical portion 33 and the guide tube 30 can be fastened and fixed by the band.
A pair of notch grooves 38 in the radial direction W are formed on the lower end side of the guide tube 30 in the axis Y direction, and an engagement piece 39 (attached part) that protrudes outward in the radial direction W from each notch groove 38. Is provided.

係合片３９は、給油キャップ１７の係合片２６と同様に円弧状に形成されている。
また、一対の係合片３９は同様の断面形状の連結部４０によって連結され、この連結部４０と係合片３９との接続部分には延設片４１が設けられ、この延設片４１が案内管３０の内面に溶接によって固着されている。
係合片３９と、連結部４０と、延設片４１とは板材によって一体形成されている。 The engagement piece 39 is formed in an arc shape like the engagement piece 26 of the fuel filler cap 17.
The pair of engaging pieces 39 are connected by a connecting portion 40 having the same cross-sectional shape, and an extending piece 41 is provided at a connecting portion between the connecting portion 40 and the engaging piece 39. It is fixed to the inner surface of the guide tube 30 by welding.
The engaging piece 39, the connecting portion 40, and the extending piece 41 are integrally formed of a plate material.

パッキン３１はゴムによって所定厚さのリング状に形成されて、案内管３０の軸心Ｙ方向下端側から外嵌されて、フランジ３６に接当している。
前記構成の給油漏斗２７を給油口１５に取りつけるには、先ず、係合片３９が切欠部１９に対応するように位置合わせする。
本実施形態の給油漏斗２７にあっては、案内管３０の軸心Ｙ方向下端側を給油口１５の上端開口に対向させると共に、燃料投入口２８が後ろ斜め下側を向く状態で、図７に仮想線で示すように、係合片３９が切欠部１９に対応する位置とされ、この状態で案内管３０の軸心方向下端側を給油口１５に挿入すると、係合片３９が切欠部１９を通して給油口１５内に挿入されると共に給油口１５の軸心方向の上端面にパッキン３１が接当する。 The packing 31 is formed in a ring shape with a predetermined thickness by rubber, and is fitted from the lower end side in the axial center Y direction of the guide tube 30 and is in contact with the flange 36.
In order to attach the refueling funnel 27 having the above configuration to the refueling port 15, first, the engagement piece 39 is aligned so as to correspond to the notch 19.
In the refueling funnel 27 of the present embodiment, the lower end side of the guide tube 30 in the direction of the axis Y is opposed to the upper end opening of the refueling port 15, and the fuel input port 28 faces obliquely downward in the rear, FIG. As shown in phantom lines, the engagement piece 39 is at a position corresponding to the notch 19, and in this state, when the lower end side in the axial center direction of the guide tube 30 is inserted into the oil supply port 15, the engagement piece 39 is notched. The gasket 31 is inserted into the fuel filler port 15 through 19 and the packing 31 contacts the upper end surface of the fuel filler port 15 in the axial direction.

この状態で、係合片３９は、平坦ガイド面２３よりも給油口１５軸心Ｘ方向外方側に位置している。そして、案内管３０（給油漏斗２７）を後ろ回りに（矢示Ｅ方向に）回動させると、係合片３９が傾斜ガイド面２２によって引き下げられ、パッキン３１を弾性変形させる。
その後、さらに案内管３０を矢示Ｅ方向に回転させると、係合片３９は平坦ガイド面２
３を摺動して係合凹部２１に至り接当部２０に当たると案内管３０（給油漏斗２７）は回り止めされて取り付けられる。この状態で、図１に示すように、燃料投入口２８が上方を向く状態となる。 In this state, the engagement piece 39 is located on the outer side in the X axis direction of the fuel filler port 15 with respect to the flat guide surface 23. Then, when the guide tube 30 (oil supply funnel 27) is rotated backward (in the direction of arrow E), the engagement piece 39 is pulled down by the inclined guide surface 22 and the packing 31 is elastically deformed.
Thereafter, when the guide tube 30 is further rotated in the direction of the arrow E, the engagement piece 39 becomes flat guide surface 2.
When the guide 3 is slid to reach the engagement recess 21 and hits the contact portion 20, the guide tube 30 (oil supply funnel 27) is prevented from rotating and attached. In this state, as shown in FIG. 1, the fuel inlet 28 faces upward.

この取付状態において、係合片３９は、パッキン３１が弾性変形しないと係合凹部２１から離脱しないので、容易に前記とは逆方向（反矢示Ｅ方向）に回転することがない。
前記構成の給油漏斗２７にあっては、給油キャップ１７の給油口１５に対する回止め構造と同様の構造によって給油漏斗２７が給油口１５に回り止めされて取りつけられるので、重量のある燃料携行缶１６を給油漏斗２７のロート部３２にのせても該燃料携行缶１６を保持することができて、給油を容易に行うことができる。 In this attached state, the engagement piece 39 does not easily disengage from the engagement recess 21 unless the packing 31 is elastically deformed. Therefore, the engagement piece 39 does not easily rotate in the direction opposite to the above (counter arrow E direction).
In the fueling funnel 27 having the above-described configuration, the fueling funnel 27 is attached to the fueling port 15 while being prevented from rotating by the same structure as the rotation-stopping structure of the fueling cap 17 with respect to the fueling port 15. The fuel carrying can 16 can be held even if it is placed on the funnel portion 32 of the refueling funnel 27, and refueling can be performed easily.

また、給油漏斗２７を斜め上方に向けて開口する傾斜状の給油口１５に取りつけても給油口１５に取り付けられた状態で燃料投入口２８が上方を向くのでノズルのない燃料携行缶１６でも給油が容易に行える。
なお、図例では、給油漏斗２７を給油口１５に取り付けた状態で、燃料投入口２８が真上を向くように形成されているが、これに限定されることはなく、給油漏斗２７を給油口１５に取り付けた状態で、燃料投入口２８の開口面が水平面に対して若干傾斜状となっていてもよく、給油漏斗２７を給油口１５に取り付けた状態で燃料投入口２８が給油口１５の開口方向よりも上側を向く（ロート部３２の中心線Ｚが給油口１５の軸心Ｘよりも上側を向く）ように構成されていればよい。 Further, even if the fueling funnel 27 is attached to the inclined fueling port 15 that opens obliquely upward, the fuel input port 28 faces upward while being attached to the fueling port 15, so that fuel is supplied even in the fuel carrying can 16 without a nozzle. Can be done easily.
In the illustrated example, the fuel charging port 27 is formed so as to face directly above with the fueling funnel 27 attached to the fueling port 15. However, the present invention is not limited to this, and the fueling funnel 27 is refueled. The opening of the fuel inlet 28 may be slightly inclined with respect to the horizontal plane when attached to the inlet 15, and the fuel inlet 28 is connected to the filler inlet 15 with the filler funnel 27 attached to the filler inlet 15. It is only necessary to be configured to face upward from the opening direction (the center line Z of the funnel portion 32 faces upward from the axis X of the fuel filler port 15).

また、案内管３０は軸心Ｙ方向上端側において、径方向Ｗ下部側が上部側よりも軸心Ｙ方向上方側に突出する形状であるので（漏斗本体２９の管挿入溝３５に対する案内管３０の差込み代が、案内管３０の径方向Ｗ上部側よりも下部側が大とされているので）、管挿入溝３５に案内管３０を挿入することで、漏斗本体２９の筒部３３と案内管３０との軸心回りの相対回転が規制され、漏斗本体２９と案内管３０との周方向の位置決めが行われる。   Further, the guide tube 30 has a shape in which the lower side in the radial direction W protrudes upward in the axis Y direction from the upper side on the upper end side in the axial center Y direction (the guide tube 30 with respect to the tube insertion groove 35 of the funnel body 29). Since the insertion allowance is larger on the lower side than the upper side in the radial direction W of the guide tube 30), the guide tube 30 is inserted into the tube insertion groove 35, so that the cylindrical portion 33 of the funnel body 29 and the guide tube 30 are inserted. Relative rotation around the axis is restricted, and positioning of the funnel body 29 and the guide tube 30 in the circumferential direction is performed.

また、燃料携行缶１６をのせても、案内管３０の管挿入溝３５への差込み部分の下部側で燃料携行缶１６の重量を受けるので、燃料携行缶１６を十分に保持できる。
また、案内管３０の下端側を給油口１５に差し込んで所定角度周方向に回動させることにより、案内管３０が回り止めされ且つ燃料投入口２８が上方を向くように取りつけられるので、給油漏斗２７の取付が容易に行える。 Even when the fuel carrying can 16 is placed, the weight of the fuel carrying can 16 is received on the lower side of the insertion portion of the guide tube 30 into the tube insertion groove 35, so that the fuel carrying can 16 can be sufficiently held.
Further, by inserting the lower end side of the guide tube 30 into the fuel filler port 15 and rotating it in the circumferential direction by a predetermined angle, the guide tube 30 is prevented from rotating and attached so that the fuel inlet 28 faces upward. 27 can be easily attached.

また、漏斗本体２９がゴム製であるので、燃料携行缶１６を漏斗本体２９にのせたときに、給油漏斗２７に作用する回転方向の力を吸収することができる。
なお、前記構成において、ゴム製のパッキン３１の替わりにバネ（板バネ、バネ鋼）を採用することができ、また、弾性変形するものであれば、その他のものであってもよい。
また、給油キャップ１７の給油口１５に対する回止め構造としては、前記実施形態の構造のものに限定されることはなく、給油口１５の内周面に形成した雌ネジに、給油キャップ１７の挿入部分の外周面に形成した雄ネジを螺合させる構造のものであってもよい。したがって、この場合は、給油漏斗２７の案内管３０の差込み部分の外周面に雄ネジを形成する。 Further, since the funnel body 29 is made of rubber, the rotational force acting on the fuel supply funnel 27 can be absorbed when the fuel carrying can 16 is placed on the funnel body 29.
In addition, in the said structure, a spring (plate spring, spring steel) can be employ | adopted instead of the rubber packing 31, and another thing may be used as long as it elastically deforms.
Further, the structure for stopping the oil supply cap 17 with respect to the oil supply port 15 is not limited to the structure of the above-described embodiment, and the oil supply cap 17 is inserted into the female screw formed on the inner peripheral surface of the oil supply port 15. It may have a structure in which a male screw formed on the outer peripheral surface of the portion is screwed. Therefore, in this case, a male screw is formed on the outer peripheral surface of the insertion portion of the guide tube 30 of the oil supply funnel 27.

また、漏斗本体２９と案内管３０とは、金属や硬質樹脂等の硬質材料によって一体形成されていてもよい。   The funnel body 29 and the guide tube 30 may be integrally formed of a hard material such as metal or hard resin.
