In a saddle-mounted vehicle including a lid that opens and closes the opening and a fuel cap that is provided separately from the lid and closes the fuel filler port, the fuel cap is an opening position that opens the fuel filler port. A link member that swings around the axis between the closed positions that close the fuel filler port and links the swing of the fuel cap and the opening / closing operation of the lid is connected to the fuel cap and the lid. ..
　第２側面によれば、第１側面の構成に加えて、前記リッドは前記軸線とは相違する回転軸線回りで揺動し、前記軸線および前記回転軸線は給油口に対して同側に配置され、前記給油口を挟んで反対側で前記リンク部材は前記フューエルキャップと前記リッドとを連結する。 According to the second side surface, in addition to the configuration of the first side surface, the lid swings around a rotation axis different from the axis, and the axis and the rotation axis are arranged on the same side with respect to the fuel filler port.

A hinge arm is further provided, which is provided in the above and is rotatably connected to the link member at a position away from the rotation axis.
　第６側面によれば、第５側面の構成に加えて、鞍乗り型車両は、前記フューエルキャップに結合されて、前記軸線から第１距離で離れて前記軸線に平行な連結軸線回りに回転自在に前記リンク部材の一端を連結する第１リンク軸と、前記ヒンジアームに結合されて、前記回転軸線から第１距離よりも大きい第２距離で離れて前記回転軸線に平行な連結軸線回りで回転自在に前記リンク部材の他端を連結する第２リンク軸とをさらに備える。 According to the sixth aspect, in addition to the configuration of the fifth aspect, the saddle-mounted vehicle is coupled to the fuel cap and is rotatable about a connecting axis parallel to the axis at a first distance away from the axis. A first link shaft that connects one end of the link member to the other, and a second link shaft that is coupled to the hinge arm and is separated from the rotation axis by a second distance larger than the first distance and rotates around the connection axis parallel to the rotation axis. A second link shaft that freely connects the other ends of the link member is further provided.
　第７側面によれば、第５または第６側面の構成に加えて、前記車体カバーは、乗員シートの後方に前記開口を配置し、前記リッドの外縁に面一に連続する外面を有するリアカウルを備え、前記支持体は前記給油口に対して車両前後方向で前方に配置される。 According to the seventh aspect, in addition to the configuration of the fifth or sixth aspect, the vehicle body cover has a rear cowl having the opening arranged behind the occupant seat and a flushly continuous outer surface on the outer edge of the lid. The support is arranged in front of the fuel filler port in the front-rear direction of the vehicle.
　第８側面によれば、第１～第７側面のいずれか１の構成に加えて、鞍乗り型車両は、前記閉じ位置に前記フューエルキャップを拘束し、もしくは、前記開口を閉じる位置に前記リッドを拘束するロック機構をさらに備える。 According to the eighth side surface, in addition to the configuration of any one of the first to seventh side surfaces, the saddle-riding vehicle restrains the fuel cap in the closed position or the lid in the position where the opening is closed. It is further equipped with a lock mechanism for restraining.
　第９側面によれば、第８側面の構成に加えて、鞍乗り型車両は、前記フューエルキャップおよび前記リッドのいずれか一方を開き方向に駆動する弾性力を発揮する弾性部材をさらに備える。 According to the ninth side surface, in addition to the configuration of the eighth side surface, the saddle-riding vehicle further includes an elastic member that exerts an elastic force for driving either one of the fuel cap and the lid in the opening direction.
　第１０側面によれば、第８または第９側面の構成に加えて、前記ロック機構は、前記軸線回りに回転自在に前記フューエルキャップを支持する部材に形成されて前記フューエルキャップの揺動を拘束する規制体を備える。 According to the tenth side surface, in addition to the configuration of the eighth or ninth side surface, the lock mechanism is formed on a member that rotatably supports the fuel cap around the axis and restrains the swing of the fuel cap. Equipped with a regulator.
　第１側面によれば、フューエルタンクへの給油にあたってリッドは開き、開口から車体カバー外の空間に向かって給油口は露出する。フューエルキャップは軸線回りで揺動して給油口を開放する。このとき、リッドとフューエルキャップとは別体に構成されることから、リッドは車体カバーの一部として自由にデザインされることができる。鞍乗り型車両の意匠性は高められることができる。その一方で、フューエルキャップの揺動とリッドの開閉動作とは連動することから、フューエルキャップの揺動またはリッドの開閉動作のいずれかに応じて、車体カバーの開口は開放され、フューエルタンクの給油口は開放される。リッドとフューエルキャップとは別体であるにも拘わらず、１つの動作でリッドおよびフューエルキャップは開放されることができる。こうして良好な意匠性が確保されると同時に給油にあたって良好な作業性は実現されることができる。 According to the first side, the lid opens when refueling the fuel tank, and the refueling port is exposed from the opening toward the space outside the vehicle body cover. The fuel cap swings around the axis to open the fuel filler port. At this time, since the lid and the fuel cap are separately configured, the lid can be freely designed as a part of the vehicle body cover. The design of the saddle-riding vehicle can be enhanced. On the other hand, since the swing of the fuel cap and the opening / closing operation of the lid are linked, the opening of the vehicle body cover is opened according to either the swing of the fuel cap or the opening / closing operation of the lid, and the fuel tank is refueled. The mouth is opened. Despite the fact that the lid and fuel cap are separate bodies, the lid and fuel cap can be opened by one operation. In this way, good designability can be ensured, and at the same time, good workability can be realized when refueling.
　第２側面によれば、給油口に対してフューエルキャップおよびリッドの開き方向が一致することから、フューエルキャップ、ヒンジアームおよびリンク部材で形成されるリンク機構の構造は簡素化されることができる。給油口の開放時に給油口に対してフューエルキャップおよびリッドは一方向に集中するので、給油口の他方向に十分に大きな空間が確保されることができる。給油ガンは車体カバーの外側から容易に給油口にアプローチすることができる。 According to the second aspect, since the opening directions of the fuel cap and the lid are the same with respect to the fuel filler port, the structure of the link mechanism formed by the fuel cap, the hinge arm and the link member can be simplified. Since the fuel cap and lid are concentrated in one direction with respect to the fuel filler port when the fuel filler port is opened, a sufficiently large space can be secured in the other direction of the fuel filler port. The refueling gun can easily approach the refueling port from the outside of the vehicle body cover.
　第３側面によれば、リッドは、フューエルキャップの揺動角と相違する角度で回転軸線回りに回転することができる。リッドの回転角はフューエルキャップの揺動角に依存せずに設定されることができる。その結果、リッドの外観はさらに自由にデザインされることができる。鞍乗り側車両の意匠性はさらに高められることができる。 According to the third side surface, the lid can rotate around the rotation axis at an angle different from the swing angle of the fuel cap. The rotation angle of the lid can be set independently of the swing angle of the fuel cap. As a result, the appearance of the lid can be designed more freely. The design of the saddle-riding vehicle can be further enhanced.
　第４側面によれば、キャップベースはフューエルキャップ、リッドおよびリンク部材をユニット化することができる。キャップベース、フューエルキャップ、リッドおよびリンク部材は予め組み立てられてフューエルタンクに組み付けられることができる。したがって、組み付けの作業性は向上することができる。 According to the fourth aspect, the cap base can unitize the fuel cap, lid and link member. The cap base, fuel cap, lid and link members can be pre-assembled and assembled into the fuel tank. Therefore, the workability of assembly can be improved.
　第５側面によれば、リッドの組み付けにあたってリッドはヒンジアームに支持される。したがって、ヒンジアームが車体カバーの内側に配置された後に、車体カバーの外側からヒンジアームにリッドは固着されることができる。予めリッドがフューエルキャップに連結されてから車体カバーの内側に組み付けられる場合に比べて、リッドの形状の自由度は広がることができる。こうしてリッドの外観はさらに自由にデザインされることができる。鞍乗り側車両の意匠性はさらに高められることができる。 According to the fifth side, the lid is supported by the hinge arm when assembling the lid. Therefore, after the hinge arm is arranged inside the vehicle body cover, the lid can be fixed to the hinge arm from the outside of the vehicle body cover. Compared with the case where the lid is connected to the fuel cap in advance and then assembled inside the vehicle body cover, the degree of freedom in the shape of the lid can be expanded. In this way, the appearance of the lid can be designed more freely. The design of the saddle-riding vehicle can be further enhanced.
　第６側面によれば、フューエルキャップ、ヒンジアームおよびリンク部材で構成されるリンク機構ではフューエルキャップの回転角に対してヒンジアームの回転角は縮小される。こうしてフューエルキャップの開放角とリッドの開放角とは相対的に調整されることができる。フューエルキャップからヒンジアームに効率的に力は伝達されることができる。 According to the sixth side surface, in the link mechanism composed of the fuel cap, the hinge arm and the link member, the rotation angle of the hinge arm is reduced with respect to the rotation angle of the fuel cap. In this way, the opening angle of the fuel cap and the opening angle of the lid can be adjusted relatively. Force can be efficiently transmitted from the fuel cap to the hinge arm.
　第７側面によれば、車両後方から給油ガンは簡単に給油口にアプローチすることができる。給油の作業性は向上する。 According to the 7th side, the refueling gun can easily approach the refueling port from the rear of the vehicle. Refueling workability is improved.
　第８側面によれば、リッドとフューエルキャップとはリンク部材で連結されることから、フューエルキャップの揺動およびリッドの開閉動作のいずれかが拘束されるだけで、フューエルキャップは閉じ位置に拘束され、リッドは開口を閉鎖することができる。フューエルキャップおよびリッドに個別にロック機構が設けられる場合に比べて、部品点数は削減されることができる。フューエルキャップおよびリッドのいずれかで拘束が解除されれば、フューエルキャップは閉じ位置から揺動することができるとともに、リッドは開口を開放することができる。良好な作業性は実現されることができる。 According to the eighth side surface, since the lid and the fuel cap are connected by a link member, the fuel cap is restrained in the closed position only by restraining either the swinging of the fuel cap or the opening / closing operation of the lid. , The lid can close the opening. The number of parts can be reduced as compared with the case where the fuel cap and the lid are individually provided with the locking mechanism. If the restraint is released by either the fuel cap or the lid, the fuel cap can swing from the closed position and the lid can open the opening. Good workability can be achieved.
　第９側面によれば、フューエルキャップまたはリッドがロック機構の拘束から解放されると、弾性力の働きでフューエルキャップは開き位置に向かって駆動され、リッドは開き方向に駆動されて開口を開放する。フューエルキャップおよびリッドはリンク部材で連結されることから、フューエルキャップおよびリッドに共通の弾性部材でフューエルキャップおよびリッドは開き方向に駆動されることができる。フューエルキャップおよびリッドに個別に弾性部材が設けられる場合に比べて、部品点数は削減されることができる。 According to the ninth aspect, when the fuel cap or lid is released from the restraint of the locking mechanism, the fuel cap is driven toward the opening position by the action of elastic force, and the lid is driven in the opening direction to open the opening. .. Since the fuel cap and the lid are connected by the link member, the fuel cap and the lid can be driven in the opening direction by the elastic member common to the fuel cap and the lid. The number of parts can be reduced as compared with the case where the fuel cap and the lid are individually provided with elastic members.
　第１０側面によれば、フューエルキャップの揺動を規制する規制体はフューエルキャップを揺動可能に支持する部材に一体であり、フューエルキャップの拘束位置は良好に管理されることができる。給油口に対してフューエルキャップの気密性は良好に確保されることができる。 According to the tenth aspect, the restricting body that regulates the swing of the fuel cap is integrated with the member that supports the fuel cap so as to be swingable, and the restraint position of the fuel cap can be well managed. The airtightness of the fuel cap with respect to the fuel filler port can be ensured well.

The link member 66 interlocks the opening / closing operation of the fuel lid 48 with the swing of the fuel cap 55. The link member 66 may be molded from, for example, a resin material.
　図５および図６に示されるように、リンク部材６６の一端は、連結軸線６４回りに相対回転自在に第１リンク軸６７でフューエルキャップ５５に結合される。第１リンク軸６７はねじ６８でフューエルキャップ５５に固定されるブッシュで構成される。ブッシュは例えば良好な耐摩耗性および摺動性を有する樹脂成形体で構成される。樹脂材には例えばＰＯＭ（ポリアセタール）樹脂が用いられることができる。連結軸線６４は軸線５６から第１距離ＤＳ１で離れる。 As shown in FIGS. 5 and 6, one end of the link member 66 is coupled to the fuel cap 55 by the first link shaft 67 so as to be relatively rotatable around the connecting axis 64. The first link shaft 67 is composed of a bush that is fixed to the fuel cap 55 with a screw 68. The bush is composed of, for example, a resin molded body having good wear resistance and slidability. For example, POM (polyacetal) resin can be used as the resin material. The connecting axis 64 is separated from the axis 56 by a first distance DS1.
　リンク部材６６の他端は、連結軸線６５回りに相対回転自在に第２リンク軸６９でヒンジアーム６３に結合される。第２リンク軸６９はねじ７１でヒンジアームに固定されるブッシュで構成される。ブッシュは例えば良好な耐摩耗性および摺動性を有する樹脂成形体で構成される。樹脂材には例えばＰＯＭ（ポリアセタール）樹脂が用いられることができる。連結軸線６５は回転軸線６２から第１距離ＤＳ１よりも大きい第２距離ＤＳ２で離れる。 The other end of the link member 66 is connected to the hinge arm 63 by the second link shaft 69 so as to be relatively rotatable around the connecting axis 65. The second link shaft 69 is composed of a bush fixed to the hinge arm by a screw 71. The bush is composed of, for example, a resin molded body having good wear resistance and slidability. For example, POM (polyacetal) resin can be used as the resin material. The connecting axis 65 separates from the rotating axis 62 at a second distance DS2, which is larger than the first distance DS1.
　ヒンジアーム６３は、回転軸線６２回りに回転自在にブッシュ７２でキャップベース５７に連結される。ブッシュ７２はねじ７３でキャップベース５７に固定される。ブッシュ７２は例えば良好な耐摩耗性および摺動性を有する樹脂成形体で構成される。樹脂材には例えばＰＯＭ（ポリアセタール）樹脂が用いられることができる。 The hinge arm 63 is rotatably connected to the cap base 57 by a bush 72 around the rotation axis 62. The bush 72 is fixed to the cap base 57 with a screw 73. The bush 72 is made of, for example, a resin molded body having good wear resistance and slidability. For example, POM (polyacetal) resin can be used as the resin material.
　ヒンジアーム６３の回転軸線６２は、フューエルキャップ５５の軸線５６から相違して軸線５６に平行に延びる。ヒンジアーム６３は、回転軸線６２から車両後方に離れた位置で、フューエルリッド４８の内面に向き合いながら広がる連結体６３ａと、連結体６３ａから下方に膨らむように湾曲しながら車両前方に延び、回転軸線６２回りに回転自在にブッシュ７２でキャップベース５７に連結される前端を有する２つの湾曲腕６３ｂとを有する。ヒンジアーム６３は例えば樹脂材から成型されればよい。湾曲腕６３ｂの間にキャップベース５７は部分的に配置される。 The rotation axis 62 of the hinge arm 63 extends parallel to the axis 56, unlike the axis 56 of the fuel cap 55. The hinge arm 63 extends from the rotation axis 62 to the rear of the vehicle, and extends to the front of the vehicle while facing the inner surface of the fuel lid 48 and extending downward from the connection 63a. It has two curved arms 63b with a front end that are rotatably connected to the cap base 57 by a bush 72. The hinge arm 63 may be molded from, for example, a resin material. The cap base 57 is partially placed between the curved arms 63b.
　図４に示されるように、フューエルリッド４８には、ヒンジアーム６３に向き合う内面から突出して、ヒンジアーム６３の連結体６３ａの前縁に受け止められる第１結合体４８ａと、第１結合体４８ａよりも車両後方で、ヒンジアーム６３に向き合う内面から突出して、ヒンジアーム６３の連結体６３ａの後縁に受け止められる第２結合体４８ｂとが形成される。第２結合体４８ｂは例えば連結体６３ａの両側に配置されるボスで形成されればよい。第１結合体４８ａには、連結体６３ａに受け止められる平面７４から突出して、後ろ向きに延びる爪を有するフック７５が形成される。第２結合体４８ｂには、連結体６３ａに受け止められる平面７６に穿たれて、内面に刻まれる雌ねじを有するねじ穴７７が形成される。フューエルリッド４８はリアカウル４３と同じ材料から成型されればよい。 As shown in FIG. 4, the fuel lid 48 has a first coupling 48a that protrudes from the inner surface facing the hinge arm 63 and is received by the front edge of the coupling 63a of the hinge arm 63, and more than the first coupling 48a. At the rear of the vehicle, a second coupling 48b is formed that projects from the inner surface facing the hinge arm 63 and is received by the trailing edge of the connecting body 63a of the hinge arm 63. The second coupling 48b may be formed of, for example, bosses arranged on both sides of the coupling 63a. The first coupling 48a is formed with a hook 75 having a claw that protrudes from the plane 74 received by the coupling 63a and extends backward. The second coupling 48b is formed with a screw hole 77 having a female screw that is bored in a flat surface 76 that is received by the coupling 63a and is carved on the inner surface. The fuel lid 48 may be molded from the same material as the rear cowl 43.
　第１結合体４８ａは、ヒンジアーム６３の連結体６３ａに形成される第１座面７８に受け止められる。第１座面７８には第１結合体４８ａのフック７５を受け入れるスリット７９が形成される。第１座面７８に対して第１結合体４８ａが位置決めされると、スリット７９内のフック７５は連結体６３ａに係り合う。第１座面７８に対して第１結合体４８ａのがたつきは防止される。フック７５は第１座面７８と第１結合体４８ａとの接触を維持する。 The first coupling body 48a is received by the first seat surface 78 formed on the connecting body 63a of the hinge arm 63. A slit 79 for receiving the hook 75 of the first coupling 48a is formed on the first seat surface 78. When the first coupling 48a is positioned with respect to the first seat 78, the hook 75 in the slit 79 engages the coupling 63a. The rattling of the first coupling 48a with respect to the first seat surface 78 is prevented. The hook 75 maintains contact between the first seat surface 78 and the first coupling 48a.
　第２結合体４８ｂは、ヒンジアーム６３の連結体６３ａに形成される第２座面８１に受け止められる。第２座面８１には、第２結合体４８ｂのねじ穴７７にねじ込まれるねじ８２の軸部を受け入れる円孔８３が形成される。第２結合体４８ｂはねじ８２でヒンジアーム６３に結合される。こうしてフック７５およびねじ８２でフューエルリッド４８はヒンジアーム６３に結合される。 The second coupling body 48b is received by the second seating surface 81 formed on the connecting body 63a of the hinge arm 63. A circular hole 83 is formed in the second seat surface 81 to receive the shaft portion of the screw 82 screwed into the screw hole 77 of the second coupling 48b. The second coupling 48b is coupled to the hinge arm 63 with a screw 82. The fuel lid 48 is thus coupled to the hinge arm 63 with hooks 75 and screws 82.
　フューエルリッド４８には、第１結合体４８ａおよび第２結合体４８ｂでヒンジアーム６３に締結されて、開口４７の前端でリアカウル４３との間で一体感を醸し出しながら上方からヒンジアーム６３を覆う天板４８ｃと、天板４８ｃから折れ曲がり、開口４７の後端でリアカウル４３との間で一体感を醸し出しながら後方から第２結合体４８ｂおよびねじ８２を覆う隠し板４８ｄとが形成される。 The fuel lid 48 is fastened to the hinge arm 63 by the first coupling 48a and the second coupling 48b, and a top plate that covers the hinge arm 63 from above while creating a sense of unity with the rear cowl 43 at the front end of the opening 47. A hidden plate 48d that bends from the top plate 48c and covers the second coupling 48b and the screw 82 is formed from the rear while creating a sense of unity between the rear cowl 43 and the rear cowl 43 at the rear end of the opening 47.
　図６に示されるように、キャップベース５７は、フィラーネック４５を囲んでフューエルタンク４４にねじ留めされる囲い板５７ａと、囲い板５７ａから連続し、給油口４４ａの外縁から外側に一方向に離れるように広がって、フューエルキャップ５５およびヒンジアーム６３に連結される支持体５７ｂとを有する。支持体５７ｂは、相互に間隔を置きながら、囲い板５７ａの表面を含む平面から立ち上がる１対の壁体８４を有する。ここでは、支持体５７ｂは、給油口４４ａに対して車両前後方向で前方に配置される。したがって、フューエルキャップ５５は給油口４４ａの開放時に給油口４４ａに対して車両前側に位置する。フューエルリッド４８は開口４７の開放時に開口４７に対して車両前側に位置する。 As shown in FIG. 6, the cap base 57 is continuous with the enclosure plate 57a which surrounds the filler neck 45 and is screwed to the fuel tank 44, and is unidirectionally outward from the outer edge of the fuel filler port 44a. It has a support 57b that extends apart and is connected to a fuel cap 55 and a hinge arm 63. The support 57b has a pair of wall bodies 84 that rise from a plane including the surface of the enclosure 57a, spaced apart from each other. Here, the support 57b is arranged forward with respect to the fuel filler port 44a in the vehicle front-rear direction. Therefore, the fuel cap 55 is located on the front side of the vehicle with respect to the fuel filler port 44a when the fuel filler port 44a is opened. The fuel lid 48 is located on the front side of the vehicle with respect to the opening 47 when the opening 47 is opened.
　フューエルキャップ５５は、軸線５６回りで揺動自在にピボットシャフト８５に連結されるキャップ本体５５ａを備える。キャップ本体５５ａは、給油口４４ａよりも大きい径を有して給油口４４ａの外縁よりも外側に広がる円板体８６と、円板体８６から車両前方に延び、回転自在にピボットシャフト８５を受け入れる貫通孔８７ａを前端に有する連結腕８７とを備える。ピボットシャフト８５は２つの壁体８４を貫通してフランジ８５ａおよびＣクリップ８８とでキャップベース５７に固定される。 The fuel cap 55 includes a cap body 55a that is swingably connected to the pivot shaft 85 around the axis 56. The cap body 55a has a diameter larger than that of the fuel filler port 44a and extends outward from the outer edge of the fuel filler port 44a, and extends from the disk body 86 to the front of the vehicle and rotatably receives the pivot shaft 85. It is provided with a connecting arm 87 having a through hole 87a at the front end. The pivot shaft 85 penetrates the two wall bodies 84 and is fixed to the cap base 57 with the flange 85a and the C clip 88.
　連結腕８７にはピボットシャフト８５に同軸に外向きに突出する１対の円筒体５５ｂが形成される。個々の円筒体５５ｂには捻りばね８９が装着される。捻りばね８９の一端はキャップベース５７に連結される。捻りばね８９の他端はフューエルキャップ５５に連結される。捻りばね８９は軸線５６回りに開き方向にフューエルキャップ５５を駆動する弾性力を発揮する。ここでは、捻りばね８９は、最大限に給油口４４ａを開放する開き位置までフューエルキャップ５５を駆動する弾性力を発揮する。 A pair of cylindrical bodies 55b are formed on the connecting arm 87 so as to project coaxially outward with the pivot shaft 85. A torsion spring 89 is attached to each of the cylindrical bodies 55b. One end of the torsion spring 89 is connected to the cap base 57. The other end of the torsion spring 89 is connected to the fuel cap 55. The torsion spring 89 exerts an elastic force for driving the fuel cap 55 in the opening direction around the axis 56. Here, the torsion spring 89 exerts an elastic force for driving the fuel cap 55 to an opening position where the fuel filler port 44a is opened to the maximum extent.
　図７に示されるように、連結腕８７には、軸線５６から遠ざかるように外面から突出するリミッター９１が形成される。軸線５６回りで変位するリミッター９１の軌道上でキャップベース５７には当たり面９２が形成される。当たり面９２は軸線５６回りに開き方向にキャップ本体５５ａの揺動を制限する。フューエルキャップ５５の揺動時にリミッター９１が当たり面９２に当たることでフューエルキャップ５５の開き位置は設定される。 As shown in FIG. 7, the connecting arm 87 is formed with a limiter 91 projecting from the outer surface so as to move away from the axis 56. A contact surface 92 is formed on the cap base 57 on the orbit of the limiter 91 which is displaced around the axis 56. The contact surface 92 limits the swing of the cap body 55a in the opening direction around the axis 56. The opening position of the fuel cap 55 is set when the limiter 91 hits the contact surface 92 when the fuel cap 55 swings.
　円板体８６には、フューエルキャップ５５の閉じ位置で、フィラーネック４５に同軸にフューエルタンク４４に向かって立ち上がる円筒壁９３が形成される。円筒壁９３の内側にはフューエルパッキン９４が装着される。フューエルパッキン９４は、給油口４４ａ回りでフィラーネック４５の先端に密着する厚肉体９４ａと、厚肉体９４ａから外側に広がる襞体９４ｂとを有する。襞体９４ｂは、円筒壁９３の内側に嵌め込まれるパッキンホルダー９５で円板体８６に結合される。フューエルパッキン９４は例えばゴム材から成型される。キャップ本体５５ａは例えばアルミニウム材から成形されればよい。パッキンホルダー９５は例えばアルミニウム材から成型されればよい。 The disk body 86 is formed with a cylindrical wall 93 that rises coaxially with the filler neck 45 toward the fuel tank 44 at the closed position of the fuel cap 55. A fuel packing 94 is mounted inside the cylindrical wall 93. The fuel packing 94 has a thick body 94a that is in close contact with the tip of the filler neck 45 around the fuel filler port 44a, and a fold body 94b that extends outward from the thick body 94a. The fold body 94b is connected to the disk body 86 by a packing holder 95 fitted inside the cylindrical wall 93. The fuel packing 94 is molded from, for example, a rubber material. The cap body 55a may be molded from, for example, an aluminum material. The packing holder 95 may be molded from, for example, an aluminum material.
　フューエルパッキン９４の厚肉体９４ａはプッシュ部材９６に支持される。プッシュ部材９６はフューエルキャップ５５の閉じ位置でフィラーネック４５との間にフューエルパッキン９４を挟み込む。プッシュ部材９６は、円板体８６から突出する案内軸９７に案内されてキャップ本体５５ａの中心軸線の線方向に変位することができる。案内軸９７の先端にはＣクリップ９８が固着される。Ｃクリップ９８は案内軸９７からのプッシュ部材９６の抜けを防止する。 The thick body 94a of the fuel packing 94 is supported by the push member 96. The push member 96 sandwiches the fuel packing 94 with the filler neck 45 at the closed position of the fuel cap 55. The push member 96 can be guided by a guide shaft 97 protruding from the disk body 86 and displaced in the line direction of the central axis of the cap body 55a. A C clip 98 is fixed to the tip of the guide shaft 97. The C clip 98 prevents the push member 96 from coming off from the guide shaft 97.
　案内軸９７回りでプッシュ部材９６と円板体８６との間には弦巻ばね９９が挟まれる。弦巻ばね９９は円板体８６から離れる方向にＣクリップ９８に向かってプッシュ部材９６に駆動力を付与する弾性力を発揮する。フューエルキャップ５５の閉じ位置では弦巻ばね９９の弾性力でフューエルパッキン９４はフィラーネック４５の先端に決められた圧力で押し付けられる。フューエルパッキン９４がフィラーネック４５の拘束から解放されると、弦巻ばね９９の弾性力でプッシュ部材９６はＣクリップ９８に押し付けられる。 A string winding spring 99 is sandwiched between the push member 96 and the disk body 86 around the guide shaft 97. The string-wound spring 99 exerts an elastic force that applies a driving force to the push member 96 toward the C clip 98 in a direction away from the disk body 86. At the closed position of the fuel cap 55, the fuel packing 94 is pressed against the tip of the filler neck 45 by the elastic force of the string winding spring 99 with a predetermined pressure. When the fuel packing 94 is released from the restraint of the filler neck 45, the push member 96 is pressed against the C clip 98 by the elastic force of the string winding spring 99.
　フューエルキャップユニット４６には、閉じ位置にフューエルキャップ５５を拘束するロック機構１０１が組み込まれる。ロック機構１０１は、一端にロック爪１０２ａを有するスライダー１０２と、キャップ本体５５ａに形成されて、線形にスライダー１０２の変位を案内する案内路１０３を区画する１対の立ち壁１０４とを備える。スライダー１０２は、フューエルキャップ５５の表面に沿って線形に変位する。ロック爪１０２ａは、スライダー１０２の変位に応じて、円板体８６の外周から最大限に外方に突出する第１位置Ｐｆと、第１位置Ｐｆから円板体８６の外周に向かって後退する第２位置Ｐｓとの間で変位する。スライダー１０２の他端はキャップ本体５５ａの縁から外方に突出する。 The fuel cap unit 46 incorporates a lock mechanism 101 that restrains the fuel cap 55 at the closed position. The lock mechanism 101 includes a slider 102 having a lock claw 102a at one end, and a pair of standing walls 104 formed on the cap body 55a to partition a guide path 103 that linearly guides the displacement of the slider 102. The slider 102 is linearly displaced along the surface of the fuel cap 55. The lock claw 102a retreats from the first position Pf toward the outer circumference of the disc body 86 and the first position Pf protruding outward from the outer circumference of the disc body 86 as much as possible according to the displacement of the slider 102. Displace with the second position Ps. The other end of the slider 102 projects outward from the edge of the cap body 55a.
　立ち壁１０４には上方から案内路１０３を塞ぐ押さえ板１０５が結合される。押さえ板１０５は、立ち壁１０４の上端から下がった段差１０４ａに受け止められ、段差１０４ａよりも上方で折り曲げられたかしめ片１０４ｂで段差１０４ａに押し当てられる。 A holding plate 105 that closes the guide path 103 is connected to the standing wall 104 from above. The pressing plate 105 is received by the step 104a lowered from the upper end of the standing wall 104, and is pressed against the step 104a by the caulking piece 104b bent above the step 104a.
　スライダー１０２の他端には案内路１０３に沿って外側から押さえ板１０５の縁に接触する突片１０２ｂが形成される。突片１０２ｂは押さえ板１０５の縁に接触することでスライダー１０２の前進を規制する。このとき、ロック爪１０２ａは、円板体８６の外周から最大限に外方に突出する第１位置Ｐｆに位置決めされる。突片１０２ｂはフューエルキャップ５５の外縁で案内路１０３を塞ぐ。 At the other end of the slider 102, a projecting piece 102b that comes into contact with the edge of the pressing plate 105 from the outside is formed along the guide path 103. The projecting piece 102b restricts the advance of the slider 102 by contacting the edge of the pressing plate 105. At this time, the lock claw 102a is positioned at the first position Pf that protrudes outward as much as possible from the outer circumference of the disk body 86. The projecting piece 102b closes the guide path 103 with the outer edge of the fuel cap 55.
　スライダー１０２には弦巻ばね１０６の収容空間１０７が区画される。弦巻ばね１０６は案内路１０３内でスライダー１０２とキャップ本体５５ａとの間に圧縮された状態で配置される。弦巻ばね１０６は、ロック爪１０２ａに近い一端でスライダー１０２に接触し、ロック爪１０２ａから遠い他端でキャップ本体５５ａに接触する。キャップ本体５５ａには、収容空間１０７内に配置されて、弦巻ばね１０６の他端を支持する壁１０８が形成される。弦巻ばね１０６は、案内路１０３に沿って第１位置Ｐｆにロック爪１０２ａを保持する弾性力を発揮する。 A storage space 107 for the string winding spring 106 is partitioned on the slider 102. The string-wound spring 106 is arranged in the guide path 103 in a compressed state between the slider 102 and the cap body 55a. The string-wound spring 106 comes into contact with the slider 102 at one end close to the lock claw 102a and with the cap body 55a at the other end far from the lock claw 102a. The cap body 55a is formed with a wall 108 arranged in the accommodation space 107 to support the other end of the string-wound spring 106. The string-wound spring 106 exerts an elastic force for holding the lock claw 102a at the first position Pf along the guide path 103.
　ロック機構１０１は、開き位置および閉じ位置の間で行き来するフューエルキャップ５５の軌道から外れた位置に配置されて、フューエルタンク４４に結合される規制体１１１を備える。規制体１１１は、捻りばね８９の弾性力に抗して軸線５６回りで第１位置Ｐｆのロック爪１０２ａを拘束することができる。第１位置Ｐｆのロック爪１０２ａは、規制体１１１に係り合って閉じ位置にフューエルキャップ５５を保持する。第２位置Ｐｓのロック爪１０２ａは、規制体１１１から離脱して閉じ位置および開き位置の間で軸線５６回りにフューエルキャップ５５の揺動を許容する。規制体１１１は、給油口４４ａに対して車両前後方向に後方でキャップベース５７に形成される。 The lock mechanism 101 includes a regulator 111 that is arranged at a position off the track of the fuel cap 55 that goes back and forth between the open position and the closed position and is coupled to the fuel tank 44. The restricting body 111 can restrain the lock claw 102a at the first position Pf around the axis 56 against the elastic force of the torsion spring 89. The lock claw 102a at the first position Pf engages with the regulator 111 to hold the fuel cap 55 at the closed position. The lock claw 102a at the second position Ps separates from the restricting body 111 and allows the fuel cap 55 to swing around the axis 56 between the closed position and the open position. The regulator 111 is formed on the cap base 57 rearward in the vehicle front-rear direction with respect to the fuel filler port 44a.
　ロック機構１０１は、軸線５６に平行なヒンジ軸線１１２回りで揺動自在にキャップベース５７の支持体５７ｂに支持される操作部材１１３をさらに備える。操作部材１１３は一方の壁体８４と連結腕８７との間に配置される。操作部材１１３には、ヒンジ軸線１１２に同軸に軸体１１３ａが形成される。軸体１１３ａは内側から壁体８４を貫通しＣクリップ１１４で抜け止めされる。 The lock mechanism 101 further includes an operating member 113 that is swingably supported by a support 57b of the cap base 57 around a hinge axis 112 parallel to the axis 56. The operating member 113 is arranged between one wall body 84 and the connecting arm 87. The operating member 113 is formed with a shaft body 113a coaxially with the hinge axis 112. The shaft body 113a penetrates the wall body 84 from the inside and is prevented from coming off by the C clip 114.
　操作部材１１３には、ヒンジ軸線１１２から遠心方向に離れた位置でケーブル５４の先端を受け止める留め片１１５が形成される。留め片１１５は例えばヒンジ軸線１１２に平行な中心軸を有する円柱体で形成される。留め片１１５にはケーブル５４の先端が連結される。 The operating member 113 is formed with a retaining piece 115 that receives the tip of the cable 54 at a position separated from the hinge axis 112 in the centrifugal direction. The clasp 115 is formed of, for example, a cylinder having a central axis parallel to the hinge axis 112. The tip of the cable 54 is connected to the retaining piece 115.
　ケーブル５４は、キャップベース５７に支持されるシース１１６に案内されてキャップベース５７に対して軸方向に相対変位することができる。シーソースイッチ５３で「ＦＵＥＬ」側が押し込まれると、ケーブル５４は引っ張られる。操作部材１１３はヒンジ軸線１１２回りで第１方向ＦＲに揺動する。操作部材１１３には、第１方向ＦＲへの揺動時に壁体８４の縁に当たって第１方向ＦＲへの揺動を制限する第１ストッパー１１７ａが形成される。第１ストッパー１１７ａは操作部材１１３の非ロック位置を規定する。 The cable 54 can be guided by the sheath 116 supported by the cap base 57 and displaced relative to the cap base 57 in the axial direction. When the "FUEL" side is pushed by the seesaw switch 53, the cable 54 is pulled. The operating member 113 swings in the first direction FR around the hinge axis 112. The operating member 113 is formed with a first stopper 117a that hits the edge of the wall body 84 when swinging in the first direction FR and limits swinging in the first direction FR. The first stopper 117a defines the unlocked position of the operating member 113.
　ケーブル５４には、操作部材１１３とキャップベース５７との間で圧縮された状態で弦巻ばね１１８が装着される。弦巻ばね１１８は、ヒンジ軸線１１２回りで第１方向ＦＲに反対向きの第２方向ＳＥに操作部材１１３を駆動する弾性力を発揮する。シーソースイッチ５３で「ＦＵＥＬ」側の押し込みが解放されると、弦巻ばね１１８の弾性力の働きで操作部材１１３はヒンジ軸線１１２回りで第２方向ＳＥに揺動する。操作部材１１３には、第２方向ＳＥへの揺動時に壁体８４の縁に当たって第２方向ＳＥへの揺動を制限する第２ストッパー１１７ｂが形成される。第２ストッパー１１７ｂは操作部材１１３のロック位置を規定する。弦巻ばね１１８の弾性力はロック位置に操作部材１１３を保持する。 A string winding spring 118 is mounted on the cable 54 in a compressed state between the operating member 113 and the cap base 57. The string-wound spring 118 exerts an elastic force for driving the operating member 113 in the second direction SE in the direction opposite to the first direction FR around the hinge axis 112. When the push on the "FUEL" side is released by the seesaw switch 53, the operating member 113 swings in the second direction SE around the hinge axis 112 by the action of the elastic force of the string winding spring 118. The operating member 113 is formed with a second stopper 117b that hits the edge of the wall body 84 when swinging in the second direction SE and limits swinging in the second direction SE. The second stopper 117b defines the lock position of the operating member 113. The elastic force of the string-wound spring 118 holds the operating member 113 at the locked position.
　操作部材１１３には、ヒンジ軸線１１２から遠心方向に離れた位置で、ヒンジ軸線１１２に平行な中心軸を有して操作部材１１３から突出する係り片１１９が形成される。係り片１１９は、例えばヒンジ軸線１１２に平行な中心軸を有する円柱体で形成される。係り片１１９は、フューエルキャップ５５が閉じ位置に位置する際に案内路１０３の延長上に配置される。係り片１１９は、操作部材１１３の動きに応じて案内路１０３の線方向に変位する。操作部材１１３がヒンジ軸線１１２回りでロック位置に位置すると、係り片１１９はキャップ本体５５ａ上の案内路１０３に最も近づく。操作部材１１３がヒンジ軸線１１２回りで非ロック位置に位置すると、係り片１１９はキャップ本体５５ａ上の案内路１０３から最も遠ざかる。 The operating member 113 is formed with a engaging piece 119 having a central axis parallel to the hinge axis 112 and projecting from the operating member 113 at a position separated from the hinge axis 112 in the centrifugal direction. The engagement piece 119 is formed of, for example, a cylinder having a central axis parallel to the hinge axis 112. The engagement piece 119 is arranged on the extension of the guide path 103 when the fuel cap 55 is in the closed position. The engagement piece 119 is displaced in the linear direction of the guide path 103 according to the movement of the operating member 113. When the operating member 113 is positioned at the locked position around the hinge axis 112, the engagement piece 119 comes closest to the guide path 103 on the cap body 55a. When the operating member 113 is located in the unlocked position around the hinge axis 112, the engagement piece 119 is farthest from the guide path 103 on the cap body 55a.
　操作部材１１３では、ロック爪１０２ａに連結される係り片１１９はヒンジ軸線１１２回りに第１角度域に配置される。係り片１１９の中心軸とヒンジ軸線１１２との距離は第１長さＬＧ１に設定される。その一方で、ケーブル５４に連結される留め片１１５はヒンジ軸線１１２回りに第１角度域から特定角度αで変位する第２角度域に配置される。留め片１１５の中心軸とヒンジ軸線１１２との距離は第１長さＬＧ１よりも大きい第２長さＬＧ２に設定される。 In the operation member 113, the engagement piece 119 connected to the lock claw 102a is arranged in the first angle region around the hinge axis 112. The distance between the central axis of the engagement piece 119 and the hinge axis 112 is set to the first length LG1. On the other hand, the clasp 115 connected to the cable 54 is arranged in a second angle region that is displaced from the first angle region by a specific angle α around the hinge axis 112. The distance between the central axis of the retaining piece 115 and the hinge axis 112 is set to the second length LG2, which is larger than the first length LG1.
　スライダー１０２の他端には、フューエルキャップ５５が閉じ位置に位置すると係り片１１９に連結され、フューエルキャップ５５が閉じ位置から開き方向に変位すると係り片１１９から解放されるフック１２１が形成される。フューエルキャップ５５が閉じ位置に位置する際に、操作部材１１３がロック位置から非ロック位置に揺動すると、ロック爪１０２ａは第１位置Ｐｆから後退して規制体１１１から離脱する第２位置Ｐｓに変位する。 At the other end of the slider 102, a hook 121 is formed which is connected to the engagement piece 119 when the fuel cap 55 is located at the closed position and is released from the engagement piece 119 when the fuel cap 55 is displaced from the closed position in the opening direction. When the operating member 113 swings from the locked position to the unlocked position when the fuel cap 55 is in the closed position, the lock claw 102a retracts from the first position Pf to the second position Ps which separates from the regulator 111. Displace.
　給油にあたってスクーター１１ではキープラグ５１のキー孔５１ａにキーが差し込まれる。キー孔５１ａの角度は「ＳＥＡＴ　ＦＵＥＬ」位置に合わせられる。続いてシーソースイッチ５３で「ＦＵＥＬ」側が押し込まれる。ケーブル５４は弦巻ばね１１８の弾性力に抗して軸方向に引っ張られる。すると、図８に示されるように、操作部材１１３はヒンジ軸１１２回りで第１方向ＦＲに回転する。操作部材１１３の揺動に応じて係り片１１９は案内路１０３の延長上で案内路１０３から遠ざかる。係り片１１９の変位に応じてスライダー１０２は弦巻ばね１０６の弾性力に抗して後退する。こうしてロック爪１０２ａに駆動力が伝わる。その結果、ロック爪１０２ａは第１位置Ｐｆから第２位置Ｐｓに後退する。駆動力は規制体１１１との係り合いからロック爪１０２ａを開放する。ロック爪１０２ａは規制体１１１から離脱する。開き方向にフューエルキャップ５５の動作は許容される。操作部材１１３は非ロック位置で停止する。 When refueling, the key is inserted into the key hole 51a of the key plug 51 on the scooter 11. The angle of the key hole 51a is adjusted to the "SEAT FUEL" position. Subsequently, the seesaw switch 53 pushes the "FUEL" side. The cable 54 is pulled axially against the elastic force of the string spring 118. Then, as shown in FIG. 8, the operating member 113 rotates around the hinge shaft 112 in the first direction FR. In response to the swing of the operating member 113, the engagement piece 119 moves away from the guide path 103 on the extension of the guide path 103. In response to the displacement of the engagement piece 119, the slider 102 retracts against the elastic force of the string winding spring 106. In this way, the driving force is transmitted to the lock claw 102a. As a result, the lock claw 102a retracts from the first position Pf to the second position Ps. The driving force releases the lock claw 102a from the engagement with the regulator 111. The lock claw 102a separates from the regulator 111. The operation of the fuel cap 55 in the opening direction is allowed. The operating member 113 stops at the unlocked position.
　フューエルキャップ５５には軸線５６回りで開き方向に捻りばね８９が作用することから、フューエルキャップ５５は閉じ位置から開き方向に揺動する。すると、図９に示されるように、フューエルキャップ５５の揺動に応じてフック１２１は係り片１１９から離脱する。スライダー１０２は操作部材１１３の拘束から解放される。したがって、弦巻ばね１０６の働きでスライダー１０２は前進し、ロック爪１０２ａは再び第１位置Ｐｆに押し付けられる。 Since the torsion spring 89 acts on the fuel cap 55 in the opening direction around the axis 56, the fuel cap 55 swings in the opening direction from the closed position. Then, as shown in FIG. 9, the hook 121 is separated from the engagement piece 119 in response to the swing of the fuel cap 55. The slider 102 is released from the restraint of the operating member 113. Therefore, the slider 102 moves forward by the action of the string winding spring 106, and the lock claw 102a is pressed against the first position Pf again.
　軸線５６回りでフューエルキャップ５５が開き方向に揺動すると、図１０に示されるように、リミッター９１はキャップベース５７の当たり面９２に当たる。当たり面９２は軸線５６回りに開き方向にフューエルキャップ５５の揺動を制限する。こうしてフューエルキャップ５５の開き位置は決定される。フューエルタンク４４の給油口４４ａは最大限に開放される。 When the fuel cap 55 swings in the opening direction around the axis 56, the limiter 91 hits the contact surface 92 of the cap base 57 as shown in FIG. The contact surface 92 limits the swing of the fuel cap 55 in the opening direction around the axis 56. In this way, the opening position of the fuel cap 55 is determined. The fuel filler port 44a of the fuel tank 44 is opened to the maximum.
　捻りばね８９の働きでフューエルキャップ５５には軸線５６回りに接線方向に駆動力が生成される。リンク部材６６の軸方向に駆動力の一成分はヒンジアーム６３に伝達される。こうしてヒンジアーム６３には回転軸線６２回りに駆動力が付与される。フューエルキャップ５５の開き動作に連動してフューエルリッド４８は開口４７を開放する。 By the action of the torsion spring 89, a driving force is generated in the fuel cap 55 in the tangential direction around the axis 56. A component of the driving force in the axial direction of the link member 66 is transmitted to the hinge arm 63. In this way, a driving force is applied to the hinge arm 63 around the rotation axis 62. The fuel lid 48 opens the opening 47 in conjunction with the opening operation of the fuel cap 55.
　フューエルキャップ５５が開き位置に到達すると、フューエルリッド４８は最大限に開口４７を開放する開放位置に至る。開放位置のフューエルリッド４８は乗員シート２３よりも上方に位置する。フューエルリッド４８が最大限に開いたときにフューエルリッド４８の下端部を通る水平面ＨＰは乗員シート２３よりも上方に位置する。このとき、フューエルリッド４８の第２結合体４８ｂおよびねじ８２は後方から隠し板４８ｄで覆われるものの、ねじ８２は下方に向かって露出する。図１１に示されるように、給油の作業者は楽に後方から開口４７を経て給油口４４ａに給油ガン１２２を挿入することができる。 When the fuel cap 55 reaches the open position, the fuel lid 48 reaches the open position where the opening 47 is opened to the maximum. The fuel lid 48 in the open position is located above the occupant seat 23. The horizontal HP passing through the lower end of the fuel lid 48 when the fuel lid 48 is fully opened is located above the passenger seat 23. At this time, the second coupling 48b and the screw 82 of the fuel lid 48 are covered with the concealing plate 48d from the rear, but the screw 82 is exposed downward. As shown in FIG. 11, the refueling operator can easily insert the refueling gun 122 into the refueling port 44a from the rear through the opening 47.
　いちど、ロック爪１０２ａが規制体１１１の拘束から解除されると、シーソースイッチ５３はユーザーの操作力から解放されることができる。すると、操作部材１１３はケーブル５４の引っ張り力から解放されることから、操作部材１１３は弦巻ばね１１８の働きでヒンジ軸１１２回りに第２方向ＳＥに回転する。操作部材１１３はロック位置に復帰する。 Once the lock claw 102a is released from the restraint of the restrictor 111, the seesaw switch 53 can be released from the user's operating force. Then, since the operating member 113 is released from the pulling force of the cable 54, the operating member 113 rotates in the second direction SE around the hinge shaft 112 by the action of the string winding spring 118. The operating member 113 returns to the locked position.
　給油が完了すると、給油の作業者は給油口４４ａから給油ガン１２２を抜き取る。続いてフューエルリッド４８が回転軸線６２回りで閉じられる。フューエルリッド４８には作業者の手で操作力が加えられる。ヒンジアーム６３には回転軸線６２回りに接線方向に駆動力が生成される。リンク部材６６の軸方向に駆動力の一成分はフューエルキャップ５５のキャップ本体５５ａに伝達される。こうしてフューエルキャップ５５には軸線５６回りで駆動力が付与される。フューエルリッド４８の閉じ動作に連動してフューエルキャップ５５は給油口４４ａを閉鎖する。 When refueling is completed, the refueling worker pulls out the refueling gun 122 from the refueling port 44a. Subsequently, the fuel lid 48 is closed around the rotation axis 62. An operating force is applied to the fuel lid 48 by the operator's hand. A driving force is generated tangentially around the rotation axis 62 on the hinge arm 63. One component of the driving force in the axial direction of the link member 66 is transmitted to the cap body 55a of the fuel cap 55. In this way, a driving force is applied to the fuel cap 55 around the axis 56. The fuel cap 55 closes the fuel filler port 44a in conjunction with the closing operation of the fuel lid 48.
　給油口４４ａの閉鎖にあたってフューエルキャップ５５が閉じ位置に向かって揺動すると、第１位置Ｐｆのロック爪１０２ａは規制体１１１に衝突する。このとき、フューエルリッド４８からさらに作業者の操作力が付与されると、規制体１１１の斜面に基づきロック爪１０２ａに第２位置Ｐｓに向かって駆動力が生成される。弦巻ばね１０６の弾性力に抗してスライダー１０２は後退する。ロック爪１０２ａは規制体１１１の斜面から離脱する。フューエルキャップ５５はさらに揺動し閉じ位置に至る。給油口４４ａは閉鎖される。ロック爪１０２ａは規制体１１１の拘束から解放されることから、弦巻ばね１０６の働きでスライダー１０２は再び前進し、ロック爪１０２ａは第１位置Ｐｆに復帰する。ロック爪１０２ａは規制体１１１に係り合う。フューエルリッド４８が作業者の操作力から解放されても、規制体１１１は閉じ位置にフューエルキャップを拘束する。 When the fuel cap 55 swings toward the closed position when the fuel filler port 44a is closed, the lock claw 102a at the first position Pf collides with the regulator 111. At this time, when an operator's operating force is further applied from the fuel lid 48, a driving force is generated on the lock claw 102a toward the second position Ps based on the slope of the regulator 111. The slider 102 retracts against the elastic force of the string spring 106. The lock claw 102a separates from the slope of the regulator 111. The fuel cap 55 further swings to reach the closed position. The refueling port 44a is closed. Since the lock claw 102a is released from the restraint of the regulator 111, the slider 102 moves forward again by the action of the string winding spring 106, and the lock claw 102a returns to the first position Pf. The lock claw 102a engages with the regulator 111. Even if the fuel lid 48 is released from the operator's operating force, the regulator 111 restrains the fuel cap in the closed position.
　フューエルキャップ５５が閉じ位置に拘束されると、プッシュ部材９６とフィラーネック４５との間にフューエルパッキン９４は挟み込まれる。プッシュ部材９６には弦巻ばね９９の働きでフィラーネック４５に向かって押し付け力が付与される。したがって、フューエルパッキン９４はプッシュ部材９６とフィラーネック４５とに密着する。フューエルキャップ５５とフィラーネック４５との間では良好な気密性が確保される。フューエルキャップ５５が閉じ位置に向かって揺動する際に、操作部材１１３は弦巻ばね１１８の働きでロック位置に保持されることから、操作部材１１３の係り片１１９に再びフック１２１は係り合う。 When the fuel cap 55 is restrained in the closed position, the fuel packing 94 is sandwiched between the push member 96 and the filler neck 45. A pressing force is applied to the push member 96 toward the filler neck 45 by the action of the string winding spring 99. Therefore, the fuel packing 94 is in close contact with the push member 96 and the filler neck 45. Good airtightness is ensured between the fuel cap 55 and the filler neck 45. When the fuel cap 55 swings toward the closed position, the operating member 113 is held in the locked position by the action of the string winding spring 118, so that the hook 121 is engaged again with the engaging piece 119 of the operating member 113.
　本実施形態では、フューエルリッド４８とフューエルキャップ５５とは別体に構成されることから、フューエルリッド４８は車体カバー１３の一部として自由にデザインされることができる。スクーター１１の意匠性は高められる。その一方で、フューエルキャップ５５の揺動とフューエルリッド４８の開閉動作とは連動することから、フューエルキャップ５５の揺動が操作されれば、車体カバー１３の開口４７は開放され、フューエルタンク４４の給油口４４ａは開放される。フューエルリッド４８とフューエルキャップ５５とは別体であるにも拘わらず、１つの動作でフューエルリッド４８およびフューエルキャップ５５は開放される。こうして良好な意匠性が確保されると同時に給油にあたって良好な作業性は実現される。 In the present embodiment, since the fuel lid 48 and the fuel cap 55 are separately configured, the fuel lid 48 can be freely designed as a part of the vehicle body cover 13. The design of the scooter 11 is enhanced. On the other hand, since the swing of the fuel cap 55 and the opening / closing operation of the fuel lid 48 are linked, if the swing of the fuel cap 55 is operated, the opening 47 of the vehicle body cover 13 is opened and the fuel tank 44 is refueled. The mouth 44a is opened. Despite the fact that the fuel lid 48 and the fuel cap 55 are separate bodies, the fuel lid 48 and the fuel cap 55 are opened by one operation. In this way, good designability is ensured, and at the same time, good workability is realized when refueling.
　しかも、フューエルリッド４８とフューエルキャップ５５とはリンク部材６６で連結されることから、フューエルキャップ５５が閉じ位置に至るとフューエルリッド４８は開口４７を閉鎖する。フューエルリッド４８の閉鎖に応じてフューエルキャップ５５は閉じ位置に位置決めされることができる。フューエルキャップ５５が給油口４４ａに装着されなければ、フューエルリッド４８は開口４７を閉鎖しない。こうしてフューエルリッド４８の観察に応じてフューエルキャップ５５の装着は簡単に確認される。フューエルキャップ５５の閉じ忘れは防止されることができる。 Moreover, since the fuel lid 48 and the fuel cap 55 are connected by the link member 66, the fuel lid 48 closes the opening 47 when the fuel cap 55 reaches the closed position. The fuel cap 55 can be positioned in the closed position in response to the closure of the fuel lid 48. If the fuel cap 55 is not attached to the fuel filler port 44a, the fuel lid 48 does not close the opening 47. In this way, the attachment of the fuel cap 55 is easily confirmed according to the observation of the fuel lid 48. Forgetting to close the fuel cap 55 can be prevented.
　本実施形態に係るスクーター１１では、フューエルリッド４８は、フューエルキャップ５５の軸線５６から相違して軸線５６に平行に延びる回転軸線６２回りで回転する。フューエルリッド４８は、フューエルキャップ５５の揺動角と相違する角度で回転軸線５５回りに回転する。フューエルリッド４８の回転角はフューエルキャップ５５の揺動角に依存せずに設定されることができる。その結果、フューエルリッド４８の外観はさらに自由にデザインされることができる。スクーター１１の意匠性はさらに高められることができる。 In the scooter 11 according to the present embodiment, the fuel lid 48 rotates around a rotation axis 62 extending parallel to the axis 56, unlike the axis 56 of the fuel cap 55. The fuel lid 48 rotates around the rotation axis 55 at an angle different from the swing angle of the fuel cap 55. The rotation angle of the fuel lid 48 can be set independently of the swing angle of the fuel cap 55. As a result, the appearance of the fuel lid 48 can be designed more freely. The design of the scooter 11 can be further enhanced.
　フューエルリッド４８の組み付けにあたってフューエルリッド４８はヒンジアーム６３に支持される。したがって、ヒンジアーム６３が車体カバー１３の内側に配置された後に、車体カバー１３の外側からヒンジアーム６３にフューエルリッド４８は固着されることができる。予めフューエルリッド４８がフューエルキャップ５５に連結されてから車体カバー１３の内側に組み付けられる場合に比べて、フューエルリッド４８の形状の自由度は広がる。こうしてフューエルリッド４８の外観はさらに自由にデザインされることができる。スクーター１１の意匠性はさらに高められることができる。 When assembling the fuel lid 48, the fuel lid 48 is supported by the hinge arm 63. Therefore, after the hinge arm 63 is arranged inside the vehicle body cover 13, the fuel lid 48 can be fixed to the hinge arm 63 from the outside of the vehicle body cover 13. Compared with the case where the fuel lid 48 is connected to the fuel cap 55 in advance and then assembled inside the vehicle body cover 13, the degree of freedom in the shape of the fuel lid 48 is widened. In this way, the appearance of the fuel lid 48 can be further freely designed. The design of the scooter 11 can be further enhanced.
　フューエルキャップ５５およびフューエルリッド４８は、フューエルタンク４４に装着されて給油口４４ａ回りで広がるキャップベース５７に支持される。キャップベース５７はフューエルキャップ５５、ヒンジアーム６３およびリンク部材６６をユニット化する。キャップベース５７、フューエルキャップ５５、ヒンジアーム６３およびリンク部材６６は予め組み立てられてフューエルタンク４４に組み付けられることができる。したがって、組み付けの作業性は向上することができる。 The fuel cap 55 and the fuel lid 48 are mounted on the fuel tank 44 and supported by a cap base 57 that extends around the fuel filler port 44a. The cap base 57 unitizes the fuel cap 55, the hinge arm 63, and the link member 66. The cap base 57, the fuel cap 55, the hinge arm 63 and the link member 66 can be preassembled and assembled to the fuel tank 44. Therefore, the workability of assembly can be improved.
　キャップベース５７は、給油口４４ａの外縁から外側に一方向に離れるように広がって、フューエルキャップ５５およびヒンジアーム６３に連結される支持体５７ｂを備える。このとき、リンク部材６６は、給油口４４ａを挟んで支持体５７ｂの反対側でフューエルキャップ５５にヒンジアーム６３を連結する。給油口４４ａに対してフューエルキャップ５５およびフューエルリッド４８の開き方向が一致することから、フューエルキャップ５５、ヒンジアーム６３およびリンク部材６６で形成されるリンク機構６１の構造は簡素化される。給油口４４ａの開放時に給油口４４ａに対してフューエルキャップ５５およびフューエルリッド４８は一方向に集中するので、給油口４４ａの他方向に十分に大きな空間が確保される。給油ガン１２２は車体カバー１３の外側から容易に給油口４４ａにアプローチすることができる。 The cap base 57 includes a support 57b that extends outward in one direction from the outer edge of the fuel filler port 44a and is connected to the fuel cap 55 and the hinge arm 63. At this time, the link member 66 connects the hinge arm 63 to the fuel cap 55 on the opposite side of the support 57b with the fuel filler port 44a interposed therebetween. Since the opening directions of the fuel cap 55 and the fuel lid 48 match with respect to the fuel filler port 44a, the structure of the link mechanism 61 formed of the fuel cap 55, the hinge arm 63, and the link member 66 is simplified. Since the fuel cap 55 and the fuel lid 48 are concentrated in one direction with respect to the fuel filler port 44a when the fuel filler port 44a is opened, a sufficiently large space is secured in the other direction of the fuel filler port 44a. The refueling gun 122 can easily approach the refueling port 44a from the outside of the vehicle body cover 13.
　本実施形態に係るリンク機構６１は、フューエルキャップ５５に結合されて、軸線５６から第１距離ＤＳ１で離れて軸線５６に平行な連結軸線６４回りに回転自在にリンク部材６６の一端を連結する第１リンク軸６７と、ヒンジアーム６３に結合されて、回転軸線６２から第１距離ＤＳ１よりも大きい第２距離ＤＳ２で離れて回転軸線６２に平行な連結軸線６５回りで回転自在にリンク部材６６の他端を連結する第２リンク軸６９とを備える。フューエルキャップ５５、ヒンジアーム６３およびリンク部材６６で構成されるリンク機構６１ではフューエルキャップ５５の回転角に対してヒンジアーム６３の回転角は縮小される。こうしてフューエルキャップ５５の開放角とフューエルリッド４８の開放角とは相対的に調整されることができる。フューエルキャップ５５からヒンジアーム６３に効率的に力は伝達されることができる。 The link mechanism 61 according to the present embodiment is coupled to the fuel cap 55 and rotatably connects one end of the link member 66 around the connecting axis 64 which is separated from the axis 56 by the first distance DS1 and is parallel to the axis 56. The link member 66, which is coupled to the 1-link shaft 67 and the hinge arm 63, is rotatably around the connecting axis 65 parallel to the rotating axis 62, separated from the rotating axis 62 by a second distance DS2 larger than the first distance DS1. A second link shaft 69 that connects the other ends is provided. In the link mechanism 61 including the fuel cap 55, the hinge arm 63, and the link member 66, the rotation angle of the hinge arm 63 is reduced with respect to the rotation angle of the fuel cap 55. In this way, the opening angle of the fuel cap 55 and the opening angle of the fuel lid 48 can be adjusted relative to each other. Force can be efficiently transmitted from the fuel cap 55 to the hinge arm 63.
　本実施形態では、キャップベース５７の支持体５７ｂは給油口４４ａに対して車両前後方向で前方に配置される。その結果、車両後方から給油ガン１２２は簡単に給油口４４ａにアプローチすることができる。給油の作業性は向上する。 In the present embodiment, the support 57b of the cap base 57 is arranged in front of the fuel filler port 44a in the front-rear direction of the vehicle. As a result, the refueling gun 122 can easily approach the refueling port 44a from the rear of the vehicle. Refueling workability is improved.
　スクーター１１は、閉じ位置にフューエルキャップ５５を拘束するロック機構１０１をさらに備える。フューエルリッド４８とフューエルキャップ５５とはリンク部材６６で連結されることから、フューエルキャップ５５の揺動が拘束されるだけで、フューエルキャップ５５は閉じ位置に拘束され、フューエルリッド４８は開口４７を閉鎖する。フューエルキャップ５５およびフューエルリッド４８に個別にロック機構が設けられる場合に比べて、部品点数は削減される。フューエルキャップ５５で拘束が解除されれば、フューエルキャップ５５は閉じ位置から揺動することができるとともに、フューエルリッド４８は開口４７を開放する。良好な作業性は実現される。 The scooter 11 further includes a lock mechanism 101 that restrains the fuel cap 55 at the closed position. Since the fuel lid 48 and the fuel cap 55 are connected by the link member 66, only the swing of the fuel cap 55 is restrained, the fuel cap 55 is restrained in the closed position, and the fuel lid 48 closes the opening 47. The number of parts is reduced as compared with the case where the fuel cap 55 and the fuel lid 48 are individually provided with the locking mechanism. When the restraint is released by the fuel cap 55, the fuel cap 55 can swing from the closed position, and the fuel lid 48 opens the opening 47. Good workability is achieved.
　スクーター１１は、フューエルキャップ５５を開き方向に駆動する弾性力を発揮する捻りばね８９をさらに備える。フューエルキャップ５５がロック機構の拘束から解放されると、弾性力の働きでフューエルキャップ５５は開き位置に向かって駆動され、フューエルリッド４８は開き方向に駆動されて開口４７を開放する。フューエルキャップ５５およびフューエルリッド４８はリンク部材６６で連結されることから、フューエルキャップ５５およびフューエルリッド４８に共通の弾性部材でフューエルキャップ５５およびフューエルリッド４８は開き方向に駆動される。フューエルキャップ５５およびフューエルリッド４８に個別に弾性部材が設けられる場合に比べて、部品点数は削減される。 The scooter 11 further includes a torsion spring 89 that exerts an elastic force that drives the fuel cap 55 in the opening direction. When the fuel cap 55 is released from the restraint of the locking mechanism, the fuel cap 55 is driven toward the opening position by the action of elastic force, and the fuel lid 48 is driven in the opening direction to open the opening 47. Since the fuel cap 55 and the fuel lid 48 are connected by the link member 66, the fuel cap 55 and the fuel lid 48 are driven in the opening direction by an elastic member common to the fuel cap 55 and the fuel lid 48. The number of parts is reduced as compared with the case where the fuel cap 55 and the fuel lid 48 are individually provided with elastic members.
　本実施形態に係るロック機構１０１は、軸線５６回りに回転自在にフューエルキャップ５５を支持するキャップベース５７に形成されてフューエルキャップ５５の揺動を拘束する規制体１１１を備える。フューエルキャップ５５と規制体１１１とは同一の部材に支持されるので、フューエルキャップ５５と規制体１１１とが別個の部材に支持される場合に比べてフューエルキャップ５５の拘束位置は良好に管理されることができる。給油口４４ａに対してフューエルキャップ５５の気密性は良好に確保される。 The lock mechanism 101 according to the present embodiment includes a restrictor 111 formed on a cap base 57 that rotatably supports the fuel cap 55 around the axis 56 and restrains the swing of the fuel cap 55. Since the fuel cap 55 and the regulator 111 are supported by the same member, the restraint position of the fuel cap 55 is better managed than when the fuel cap 55 and the regulator 111 are supported by separate members. be able to. The airtightness of the fuel cap 55 with respect to the fuel filler port 44a is well ensured.
