Description
本発明は、上述した事情に鑑みてなされたものであり、燃料タンクにおいて、給油口の周囲の部分の強度を簡単な構成で高くできるようにすることを目的とする。
燃料タンクは、燃料を貯留する燃料タンク本体と、給油口とを備える燃料タンクにおいて、前記燃料タンク本体を貫通する開口が設けられ、前記開口を塞ぐ板部材が前記燃料タンク本体に溶接され、前記板部材の強度は前記燃料タンク本体の強度よりも高く、前記給油口は、前記板部材に設けられることを特徴とする。
また、上述の構成において、前記板部材は、前記開口の周縁部に重ねて設けられ、前記板部材の面において前記周縁部に対し重なる側の面である重なり面と、前記周縁部とが、前記周縁部の内周面に沿う溶接部によって溶接されても良い。
また、上述の構成において、前記板部材は、前記燃料タンク本体の内側から前記周縁部に重なっても良い。
また、上述の構成において、前記燃料タンクは、鞍乗り型車両に搭載され、前記鞍乗り型車両は、前記鞍乗り型車両を左右の一方に傾斜した状態に支持するサイドスタンドを備え、前記給油口を開閉可能に塞ぐ燃料キャップが設けられ、前記燃料キャップは、前記給油口を塞ぐキャップ本体と、前記キャップ本体を開閉自在に支持するフレーム部とを備え、前記フレーム部は、前記キャップ本体を周囲から囲む環状部と、前記環状部から下方に突出する突出部とを備え、前記突出部は、液体が溜まる凹部を備え、前記凹部の側面において前記サイドスタンドによって前記鞍乗り型車両を支持した状態で低くなる側の側面には、前記液体を排出する排出口が設けられても良い。
この構成によれば、燃料タンク本体の開口に板部材を溶接して塞ぐため、燃料タンク本体よりも強度が高い板部材を燃料タンクに簡単に設けることができる。そして、板部材に給油口が設けられる。このため、給油口の周囲の部分の強度を簡単な構成で高くできる。
この構成によれば、簡単な構成で、板部材の強度を高くできる。また、燃料タンク本体の板厚を小さくできるため、燃料タンクを軽量化できる。
また、上述の構成において、板部材は、開口の周縁部に重ねて設けられ、板部材の面において周縁部に対し重なる側の面である重なり面と、周縁部とが、周縁部の内周面に沿う溶接部によって溶接されても良い。
この構成によれば、開口の周縁部が、板厚が厚い板部材の重なり面に溶接されるため、板部材に対する溶接の深さを大きくでき、良好に溶接できる。
また、上述の構成において、板部材は、燃料タンク本体の内側から前記周縁部に重なっても良い。
この構成によれば、板部材が燃料タンク本体の外側に出っ張ることを防止でき、燃料タンクをコンパクトにできるとともに、燃料タンクの外観性が良い。また、燃料タンクの外側から板部材と燃料タンク本体とを溶接でき、溶接の作業性が良い。
この構成によれば、燃料キャップは、燃料キャップ締結部を介し、板厚が厚い板部材に締結されるため、燃料キャップを強固に固定できる。このため、燃料キャップによって給油口を良好に塞ぐことができる。
また、上述の構成において、燃料タンクは、鞍乗り型車両に搭載され、鞍乗り型車両は、鞍乗り型車両を左右の一方に傾斜した状態に支持するサイドスタンドを備え、給油口を開閉可能に塞ぐ燃料キャップが設けられ、燃料キャップは、給油口を塞ぐキャップ本体と、キャップ本体を開閉自在に支持するフレーム部とを備え、フレーム部は、キャップ本体を周囲から囲む環状部と、環状部から下方に突出する突出部とを備え、突出部は、液体が溜まる凹部を備え、凹部の側面においてサイドスタンドによって鞍乗り型車両を支持した状態で低くなる側の側面には、液体を排出する排出口が設けられても良い。

外気をエンジン11用の吸気として取り込むエアクリーナーボックス35は、クランクケース30よりも前方且つヘッドパイプ15よりも後方で、上下方向においてシリンダー部31とメインフレーム16との間に配置される。エアクリーナーボックス35は、メインフレーム16の下方に位置し、シリンダー部31に上方から重なる。エアクリーナーボックス35は、スロットルボディ34の前上方に位置する。
エアクリーナーボックス35は、エアクリーナーボックス35の後部から後方に延びる接続菅36によってスロットルボディ34に接続される。
燃料タンク38の燃料は、吸気通路に設けられる燃料供給装置(不図示)によって、上記吸気ポートに供給される。
車体カバー40は、燃料タンク38を外側方から覆う左右一対のタンクカバー41と、燃料タンク38を上方から覆う上面カバー42とを備える。

自動二輪車1は、前輪2を上方から覆うフロントフェンダー45と、後輪3を上方から覆うリアフェンダー46とを備える。
自動二輪車1は、駐車時に路面に接地して自動二輪車1を支持するサイドスタンド48を備える。サイドスタンド48は、ピボットフレーム17の下部の左側に設けられており、車幅方向の中央に対して左側にオフセットして配置される。
サイドスタンド48によって自動二輪車1を駐車した状態では、自動二輪車1は、左側に傾斜する。
燃料タンク38の上面38aには、上面38aに対し上方に延びる円筒状の口金50が設けられる。口金50は、燃料タンク38の内部を外部に連通させる筒状部材である。
口金50の内周部が区画する開口は、給油口50aである。燃料は、給油口50aから燃料タンク38内に注入される。給油口50aは、車幅方向の中央に位置する。
図2~図4を参照し、燃料タンク38には、給油口50aを開閉可能に塞ぐ燃料キャップ55が取り付けられる。
また、燃料タンク38の上面38aには、口金50を周囲から囲むトレー状の燃料受け部材56が設けられる。
燃料受け部材56は、口金50の周囲に配置される底壁部57と、底壁部57から上方に延出する周壁部58とを備える。
底壁部57は、上面視で略円形の板であり、中央部に開口57aを備える。燃料受け部材56は、開口57aが口金50の外周に嵌合した状態で、燃料タンク38の上面38aに載置される。
底壁部57は、底壁部57を上下に貫通する取付孔57bを開口57aの周囲に備える。
周壁部58の上端58aは、口金50の上端50bよりも上方に位置する。
周壁部58の下部には、排水孔58b(図5)が設けられる。排水孔58bは、周壁部58の左側面に設けられており、車幅方向の中央に対し左側にオフセットされている。
排水孔58bは、燃料受け部材56の内側を外側に連通させる。
排水孔58bには、周壁部58の外側から排水ホース(不図示)が接続される。
サイドスタンド48で自動二輪車1を支持して駐車すると、燃料受け部材56は、車体と一体に傾斜して左側の部分が低くなる。このため、燃料受け部材56が受けた液体を、排水孔58bに効率良く流すことができる。
カバー開口42aの周縁部42bは、燃料受け部材56の周壁部58の上端58aの外周部に接続される。
キャップ本体60は、平面視で略円形の蓋であり、給油口50aを上方から覆う。
フレーム部61は、キャップ本体60を周囲から囲む環状部62と、環状部62から燃料受け部材56の底壁部57に向けて下方に突出する突出部63とを備える。
燃料キャップ55は、燃料受け部材56内に収納される。環状部62の外周は、燃料受け部材56の周壁部58の内周に嵌合する。
環状部62には、環状部62を上下に貫通する固定孔62bが周方向に複数設けられる。
燃料キャップ55は、環状部62の固定孔62bに上方から挿通される燃料キャップ固定具64によって、燃料タンク38に固定される。
一方、自動二輪車1では、突出部63は、燃料受け部材56の底壁部57に当接しない。このため、燃料キャップ55を燃料タンク38に取り付けできる。
凹部63aの左側面には、凹部63aの液体を排出する排出口63bが設けられる。凹部63aの左側面は、凹部63aの側面において、サイドスタンドによって自動二輪車1を支持した状態で低くなる側の側面である。排出口63bから排出される液体は、燃料受け部材56内を通り、排水孔58bから外部に排出される。
上半体73は、下面が下方に開放するケース状である。下半体74は、上面が上方に開放するケース状である。上半体73及び下半体74は、板材をプレス加工等によって成形してケース状に形成される。
燃料タンク本体70は、上半体73の下面部と下半体74の上面部とを溶接によって接合することでタンク状に形成される。
開口75は、上面視で円形である。
板部材71は、開口75の周縁部75aに溶接されて、開口75を塞ぐ。口金50は、板部材71に設けられる。
図2及び図6を参照し、板部材71は、上面視で、開口75よりも大径の円板である。
板部材71と燃料タンク本体70とは、同じ材料で構成される。板部材71の板厚t1は、燃料タンク本体70の板厚t2よりも大きい。本実施の形態では、板厚t1は、板厚t2の2倍以上の厚さである。このため、板部材71の強度は、燃料タンク本体70の強度よりも高い。
なお、板部材71を構成する材料として、燃料タンク本体70を構成する材料よりも強度が高い材料を用いることで、板部材71の強度を燃料タンク本体70の強度よりも高くしても良い。
板部材71の面において、開口75の周縁部75aに対し板厚方向に重なる側の面は、重なり面71bである。
板部材71は、燃料タンク本体70の内側であって下方から開口75の周縁部75aに重なる。このため、重なり面71bは、板部材71の上面である。
開口75の部分では、板部材71は、燃料タンク本体70の板厚の分だけ周縁部75aに対し下方に位置する。このため、開口75の内側には、板部材71が周縁部75aに対し低くなった段部76が形成される。
溶接部77は、板部材71の上面である重なり面71b上を内周面75bに沿って一周する円環状の溶接ビードである。
このように、溶接部77が、板厚が厚い板部材71の上面に溶接されるため、板部材71に対する溶接部77の溶接深さを大きくでき、良好に溶接できる。
例えば、板部材71の周縁部71aの外周面71cと開口75の周縁部75aの下面とを溶接する場合、板厚の薄い燃料タンク本体70の下面に溶接部が形成されるため、溶接部が燃料タンク本体70を板厚方向に貫通し易くなり、溶接が難しくなる。
詳細には、口金50は、車幅方向では、円形の板部材71の中心に位置する。
口金50は、前後方向では、板部材71の中心に対し、前方側にオフセットして配置される。このため、口金50の前端と開口75の周縁部75aとの距離は、口金50の後端と開口75の周縁部75aとの距離よりも小さい。すなわち、上面視において、口金50の部分を除いた板部材71の面積は、板部材71の前部よりも後部で大きい。
口金50は、口金支持孔部78の内周に嵌合する。口金50は、口金50の外周に沿う溶接ビード78aによって、口金支持孔部78の周縁部に溶接される。
詳細には、燃料キャップ締結部80は、板部材71の幅方向の中央において口金50の前方に一つ設けられる。
また、燃料キャップ締結部80は、口金50の後方において板部材71の幅方向の中央に対し左右に一対で設けられる。
燃料キャップ締結部80は、上下に延びる筒状部材の内周に雌ねじ部80aが設けられたナットである。燃料キャップ締結部80は、板部材71の上面に溶接される。燃料キャップ固定具64は、雌ねじ部80aに締結される。
環状部62の底面は、燃料受け部材56において取付孔57bが設けられた部分を上方から押さえ、燃料受け部材56を燃料キャップ締結部80に対し抜け止めする。
この構成によれば、燃料タンク本体70の開口75に板部材71を溶接して塞ぐため、燃料タンク本体70よりも強度が高い板部材71を燃料タンク38に簡単に設けることができる。そして、板部材71に給油口が設けられる。このため、給油口50aの周囲の部分の強度を簡単な構成で高くできる。
この構成によれば、簡単な構成で、板部材71の強度を高くできる。また、燃料タンク本体70の板厚t2を小さくできるため、燃料タンク38を軽量化できる。
また、板部材71は、開口75の周縁部75aに重ねて設けられ、板部材71の面において周縁部75aに対し重なる側の面である重なり面71bと、周縁部75aとが、周縁部75aの内周面75bに沿う溶接部77によって溶接される。
この構成によれば、開口75の周縁部75aが、板厚が厚い板部材71の重なり面71bに溶接されるため、板部材71に対する溶接の深さを大きくでき、良好に溶接できる。
また、板部材71は、燃料タンク本体70の内側から周縁部75aに重なる。
この構成によれば、板部材71が燃料タンク本体70の外側に出っ張ることを防止でき、燃料タンク38をコンパクトにできるとともに、燃料タンク38の外観性が良い。また、燃料タンク38の外側から板部材71と燃料タンク本体70とを溶接でき、溶接の作業性が良い。
この構成によれば、燃料キャップ55は、燃料キャップ締結部80を介し、板厚が厚い板部材71に締結されるため、燃料キャップ55を強固に固定できる。このため、燃料キャップ55によって給油口50aを良好に塞ぐことができる。
また、燃料タンク38は、自動二輪車1に搭載され、自動二輪車1は、自動二輪車1を左右の一方に傾斜した状態に支持するサイドスタンド48を備え、給油口50aを開閉可能に塞ぐ燃料キャップ55が設けられ、燃料キャップ55は、給油口50aを塞ぐキャップ本体60と、キャップ本体60を開閉自在に支持するフレーム部61とを備え、フレーム部61は、キャップ本体60を周囲から囲む環状部62と、環状部62から下方に突出する突出部63とを備え、突出部63は、液体が溜まる凹部63aを備え、凹部63aの側面においてサイドスタンド48によって自動二輪車1を支持した状態で低くなる側の側面には、液体を排出する排出口63bが設けられる。
この構成によれば、サイドスタンド48で自動二輪車1を支持した状態では、燃料キャップ55のフレーム部61の凹部63aに溜まる液体を、自動二輪車1の傾斜によって排出口63bから排出できる。
上記実施の形態では、板部材71は、燃料タンク本体70の内側から周縁部75aに重なるものとして説明したが、本発明はこれに限定されない。例えば、板部材71は、燃料タンク本体70の外側の上方から開口75の周縁部75aに重なっても良い。この場合、重なり面である板部材71の下面と、開口75の周縁部75aとが、周縁部75aの内周面75bに沿う溶接部によって溶接される。
また、上記実施の形態では、燃料キャップ55の環状部62から下方に突出する突出部63の凹部63aに排出口63bが設けられる構成を説明したが、他の箇所に排出口を適用しても良い。例えば、ヘルメットや小物等の物品を収納可能な収納部に、液体が溜まる凹部が設けられ、この凹部の側面においてサイドスタンド48によって自動二輪車1を支持した状態で低くなる側の側面に、液体を排出する排出口が設けられても良い。この構成によれば、収納部から凹部に流れる液体を自動二輪車1の傾斜を利用して排出口から排出できる。
また、上記実施の形態では、自動二輪車1を例に挙げて説明したが、本発明はこれに限定されるものではなく、本発明は、前輪または後輪を2つ備える3輪の鞍乗り型車両及び4輪以上を備える鞍乗り型車両に適用可能である。
