燃料タンク１４は、樹脂製とされ、内部に自動車の燃料を収容可能とされている。この燃料タンク１４は、車体１２のフロアパネル１８よりも車両下方に配置されており、タンク上面１４Ａとフロアパネル１８の下面１８Ａとの間に弾性変形可能なクッション材２０（例えば、ゴム）を介した状態でタンクバンド１６によって車両下方側から支持されている。なお、本発明は上記構成に限定されず、燃料タンク１４は、タンク上面１４Ａとフロアパネル１８に取り付けられた部材（例えば、ブラケットや各種メンバ）との間に弾性変形可能なクッション材２０を介した状態でタンクバンド１６によって車両下方から支持されてもよい。   The fuel tank 14 is made of resin and can accommodate automobile fuel therein. The fuel tank 14 is disposed below the vehicle on the floor panel 18 of the vehicle body 12, and an elastically deformable cushion material 20 (for example, rubber) is interposed between the tank upper surface 14 </ b> A and the lower surface 18 </ b> A of the floor panel 18. In this state, the tank band 16 supports the vehicle from below. The present invention is not limited to the above-described configuration, and the fuel tank 14 has an elastically deformable cushion material 20 interposed between a tank upper surface 14A and members (for example, brackets and various members) attached to the floor panel 18. In this state, the tank band 16 may support the vehicle from below.

燃料タンク１４の外周には、車両上下方向に対して交差する方向（本実施形態では、直交する方向）に張り出す板状のフランジ部２２が設けられている。具体的には、フランジ部２２は、燃料タンク１４の車両前方側のタンク前面１４Ｂに車幅方向に間隔をあけて複数（本実施形態では、２つ）設けられている。このフランジ部２２には、締結具の一例としてのボルト２４（本実施形態ではフランジ付きボルト）の軸部が貫通する貫通孔２６が形成されている。   A plate-like flange portion 22 is provided on the outer periphery of the fuel tank 14 so as to project in a direction intersecting the vehicle vertical direction (in the present embodiment, a direction orthogonal). Specifically, a plurality (two in the present embodiment) of the flange portions 22 are provided on the tank front surface 14B on the vehicle front side of the fuel tank 14 with an interval in the vehicle width direction. The flange portion 22 is formed with a through hole 26 through which a shaft portion of a bolt 24 (in this embodiment, a flanged bolt) as an example of a fastener passes.

燃料タンク１４の下部には、燃料タンク１４の内側に凹み且つ車両前後方向に延びる凹溝２８が車幅方向に間隔をあけて複数（本実施形態では、２つ）形成されている。この凹溝２８には、タンクバンド１６の後述するタンク支持部１６Ａが入り込んでいる。具体的には、それぞれの凹溝２８には、それぞれ対応するタンクバンド１６のタンク支持部１６Ａが入り込んでいる。   A plurality of (two in this embodiment) concave grooves 28 that are recessed inside the fuel tank 14 and that extend in the vehicle front-rear direction are formed in the lower portion of the fuel tank 14. A tank support portion 16 </ b> A (described later) of the tank band 16 enters the concave groove 28. Specifically, the tank support portions 16 </ b> A of the corresponding tank bands 16 enter the respective concave grooves 28.

図１に示されるように、タンクバンド１６は、長尺な金属板をハット状に折り曲げて形成されている。このタンクバンド１６は、車体１２のフロアパネル１８よりも車両下方に配置され、タンク上面１４Ａとフロアパネル１８の下面１８Ａとの間にクッション材２０を介した状態で燃料タンク１４を車両下方側から支持している。具体的には、タンクバンド１６は、長手方向の一端部（車体固定部１６Ｂ）及び他端部（車体固定部１６Ｃ）が長手方向の中央部（タンク支持部１６Ａ）よりも上方に位置する姿勢（図２参照）で車体１２に締結固定されており、タンク支持部１６Ａが燃料タンク１４の凹溝２８に入り込んだ状態で燃料タンク１４を車両下方側から支持している。   As shown in FIG. 1, the tank band 16 is formed by bending a long metal plate into a hat shape. The tank band 16 is disposed below the vehicle with respect to the floor panel 18 of the vehicle body 12, and the fuel tank 14 is disposed from the vehicle lower side with a cushion material 20 interposed between the tank upper surface 14 </ b> A and the lower surface 18 </ b> A of the floor panel 18. I support it. Specifically, the tank band 16 has a posture in which one end portion in the longitudinal direction (vehicle body fixing portion 16B) and the other end portion (vehicle body fixing portion 16C) are positioned above the central portion in the longitudinal direction (tank support portion 16A). (See FIG. 2), the fuel tank 14 is fastened and fixed to the vehicle body 12, and the fuel tank 14 is supported from the lower side of the vehicle in a state where the tank support portion 16A enters the concave groove 28 of the fuel tank 14.

タンクバンド１６について具体的に説明すると、長手方向の中央部はタンク支持部１６Ａとされ、長手方向の一端部はフロアパネル１８にブラケット３０を介してボルト２４で締結固定される車体固定部１６Ｂ（図２参照）とされ、長手方向の他端部はフロアパネル１８に図示しないブラケットを介してボルト２４で締結固定される車体固定部１６Ｃ（図１参照）とされている。また、タンクバンド１６の長手方向の中央部と一端部との間の部分はタンク支持部１６Ａと車体固定部１６Ｂをつなぐ連結部１６Ｄ（図２参照）とされ、タンクバンド１６の長手方向の中央部と他端部との間の部分はタンク支持部１６Ａと車体固定部１６Ｃをつなぐ連結部１６Ｅ（図１参照）とされている。なお、本実施形態では、図１に示されるように、タンクバンド１６の長手方向の一端部が車両前方に配置され、長手方向の他端部が車両後方に配置されている。   The tank band 16 will be described in detail. The center portion in the longitudinal direction is a tank support portion 16A, and one end portion in the longitudinal direction is fastened and fixed to the floor panel 18 with a bolt 24 via a bracket 30 ( The other end portion in the longitudinal direction is a vehicle body fixing portion 16C (see FIG. 1) that is fastened and fixed to the floor panel 18 by a bolt 24 via a bracket (not shown). Further, a portion between the center portion and one end portion of the tank band 16 in the longitudinal direction is a connecting portion 16D (see FIG. 2) that connects the tank support portion 16A and the vehicle body fixing portion 16B. A portion between the first end portion and the other end portion is a connecting portion 16E (see FIG. 1) that connects the tank support portion 16A and the vehicle body fixing portion 16C. In the present embodiment, as shown in FIG. 1, one end of the tank band 16 in the longitudinal direction is disposed in the front of the vehicle, and the other end in the longitudinal direction is disposed in the rear of the vehicle.

なお、車体固定部１６Ｂ及び車体固定部１６Ｃには、ボルト２４の軸部が貫通する貫通孔３２がそれぞれ形成されている。   The vehicle body fixing portion 16B and the vehicle body fixing portion 16C are respectively formed with through holes 32 through which the shaft portion of the bolt 24 passes.

図２に示されるように、車体固定部１６Ｂとブラケット３０との間には、略円筒状の防振装置３４が配置されており、この防振装置３４の内部をボルト２４の軸部が貫通している。ボルト２４は、軸部が車体固定部１６Ｂの貫通孔３２、防振装置３４の内部及びブラケット３０に形成された貫通孔３６を貫通して軸部先端側がブラケット３０の貫通孔３６の上縁部に配置されたナット３８に捩じ込まれている。言い換えると、タンクバンド１６の車体固定部１６Ｂと防振装置３４とがボルト２４による共締めによってブラケット３０を介して車体１２のフロアパネル１８に締結固定されている。なお、本実施形態では、燃料タンク１４のフランジ部２２と防振装置３４とが接続されているため、防振装置３４と共にフランジ部２２もボルト２４による共締めによってブラケット３０を介して車体１２のフロアパネル１８に締結固定されている。言い換えると、防振装置３４を介してフランジ部２２と車体固定部１６Ｂとがボルト２４による共締めによって車体１２に締結固定されている。   As shown in FIG. 2, a substantially cylindrical vibration isolator 34 is disposed between the vehicle body fixing portion 16 </ b> B and the bracket 30, and the shaft portion of the bolt 24 penetrates the vibration isolator 34. doing. The bolt 24 passes through the through hole 32 of the vehicle body fixing portion 16B, the inside of the vibration isolator 34 and the through hole 36 formed in the bracket 30, and the front end of the shaft portion is the upper edge of the through hole 36 of the bracket 30. Is screwed into a nut 38 disposed in In other words, the vehicle body fixing portion 16 </ b> B of the tank band 16 and the vibration isolator 34 are fastened and fixed to the floor panel 18 of the vehicle body 12 via the bracket 30 by joint fastening with the bolts 24. In the present embodiment, since the flange portion 22 of the fuel tank 14 and the vibration isolator 34 are connected, the flange portion 22 and the vibration isolator 34 together with the vibration isolator 34 are fastened together with the bolts 24 via the bracket 30. It is fastened and fixed to the floor panel 18. In other words, the flange portion 22 and the vehicle body fixing portion 16 </ b> B are fastened and fixed to the vehicle body 12 by the bolts 24 through the vibration isolator 34.

図２に示されるように、防振装置３４は、フランジ部２２の貫通孔２６を貫通する略円筒状の筒部材４０と、筒部材４０の外周に沿って配置される略円筒状の防振ゴム４２と、を備えている。   As shown in FIG. 2, the vibration isolator 34 includes a substantially cylindrical tube member 40 that passes through the through hole 26 of the flange portion 22, and a substantially cylindrical vibration isolator disposed along the outer periphery of the tube member 40. Rubber 42.

筒部材４０の軸方向の一端部（車体固定部１６Ｂ側の端部）には、径方向外側に張り出す環状の鍔部４４が形成され、筒部材４０の軸方向の他端部（ブラケット３０側の端部）には径方向外側に張り出す環状の鍔部４６が形成されており、鍔部４４と鍔部４６との間に防振ゴム４２が配置されて防振ゴム４２が筒部材４０の外周に保持されている。また、本実施形態では、鍔部４４と鍔部４６の各々の外径をフランジ部２２の貫通孔２６の内径よりも大きくしている。なお、本実施形態の筒部材４０は、鍔部４４が形成された金属製のカラー４８と、鍔部４６が形成された金属製のカラー５０を接続して形成されている。   An annular flange 44 projecting radially outward is formed at one end of the cylindrical member 40 in the axial direction (end on the side of the vehicle body fixing portion 16B), and the other axial end of the cylindrical member 40 (the bracket 30). An annular flange 46 projecting radially outward is formed at the end of the side, and an anti-vibration rubber 42 is disposed between the flange 44 and the flange 46 so that the anti-vibration rubber 42 is a cylindrical member. 40 is held on the outer periphery. In the present embodiment, the outer diameter of each of the flange portion 44 and the flange portion 46 is larger than the inner diameter of the through hole 26 of the flange portion 22. Note that the cylindrical member 40 of the present embodiment is formed by connecting a metal collar 48 in which the collar portion 44 is formed and a metal collar 50 in which the collar portion 46 is formed.

防振ゴム４２の軸方向の中間部には、フランジ部２２の貫通孔２６を貫通する小径部４２Ａが形成されている。この小径部４２Ａの外周面は、貫通孔２６の孔壁面に当接している。また、防振ゴム４２の小径部４２Ａの軸方向両側には、小径部４２Ａよりも径が大きい大径部４２Ｂが形成されており、小径部４２Ａと大径部４２Ｂとの間には径差によって段差部４２Ｃが形成されている。この防振ゴム４２の段差部４２Ｃには、フランジ部２２の貫通孔２６の縁部が当接している。具体的には、車両上方の段差部４２Ｃには、フランジ部２２の貫通孔２６の上縁部が当接し、車両下方の段差部４２Ｃには、フランジ部２２の貫通孔２６の下縁部が当接している。このように燃料タンク１４のフランジ部２２は防振ゴム４２を介して筒部材４０に連結されていることから、燃料タンク１４内を流れる燃料の流動音（振動）は防振ゴム４２で減衰され、筒部材４０が締結固定されるブラケット３０を通じて車体１２に伝達されるのが抑制される。   A small-diameter portion 42 </ b> A that penetrates the through hole 26 of the flange portion 22 is formed in the middle portion in the axial direction of the vibration-proof rubber 42. The outer peripheral surface of the small diameter portion 42 </ b> A is in contact with the hole wall surface of the through hole 26. Further, large-diameter portions 42B having a diameter larger than that of the small-diameter portion 42A are formed on both axial sides of the small-diameter portion 42A of the vibration-proof rubber 42, and there is a difference in diameter between the small-diameter portion 42A and the large-diameter portion 42B. Thus, a step portion 42C is formed. The edge portion of the through hole 26 of the flange portion 22 is in contact with the step portion 42 </ b> C of the vibration isolating rubber 42. Specifically, the upper edge portion of the through hole 26 of the flange portion 22 abuts on the step portion 42C above the vehicle, and the lower edge portion of the through hole 26 of the flange portion 22 contacts the step portion 42C below the vehicle. It is in contact. Since the flange portion 22 of the fuel tank 14 is thus connected to the cylindrical member 40 via the vibration isolating rubber 42, the flow sound (vibration) of the fuel flowing through the fuel tank 14 is attenuated by the vibration isolating rubber 42. The transmission of the cylindrical member 40 to the vehicle body 12 through the bracket 30 to which the cylindrical member 40 is fastened and fixed is suppressed.

次に、本実施形態の燃料タンク取付構造１０の作用を説明する。
燃料タンク取付構造１０では、防振装置３４を介して燃料タンク１４のフランジ部２２とタンクバンド１６の車体固定部１６Ｂとをボルト２４による共締めによってフランジ部２２を介して車体１２に固定していることから、例えば、フランジ部２２とタンクバンド１６の車体固定部１６Ｂ、１６Ｃとを車体１２のそれぞれ異なる位置にボルト２４で固定するものと比べて、燃料タンク１４を車体１２に取り付けるための締結点を低減できる。これにより、燃料タンク１４を車体１２へ取り付けるためのボルト２４の数量を低減できる。またボルト２４の締結作業を軽減できる。 Next, the operation of the fuel tank mounting structure 10 of this embodiment will be described.
In the fuel tank mounting structure 10, the flange portion 22 of the fuel tank 14 and the vehicle body fixing portion 16 </ b> B of the tank band 16 are fixed to the vehicle body 12 via the flange portion 22 by tightening with bolts 24 via the vibration isolator 34. Therefore, for example, compared to fixing the flange portion 22 and the vehicle body fixing portions 16B and 16C of the tank band 16 at different positions of the vehicle body 12 with bolts 24, fastening for attaching the fuel tank 14 to the vehicle body 12 is performed. Points can be reduced. Thereby, the quantity of the bolts 24 for attaching the fuel tank 14 to the vehicle body 12 can be reduced. Moreover, the fastening work of the bolt 24 can be reduced.

また、燃料タンク取付構造１０では、燃料タンク１４を樹脂製としていることから、樹脂の膨潤によってフランジ部２２が延びやすい傾向にあるが、防振装置３４と車体固定部１６Ｂとをボルト２４による共締めによって車体１２に固定することから、防振装置３４に接続されるフランジ部２２がタンクバンド１６によって拘束され、フランジ部２２の変形（延び変形）が抑制される。   In the fuel tank mounting structure 10, since the fuel tank 14 is made of resin, the flange portion 22 tends to extend due to resin swelling. However, the vibration isolator 34 and the vehicle body fixing portion 16 </ b> B are connected together by the bolt 24. Since it fixes to the vehicle body 12 by fastening, the flange part 22 connected to the vibration isolator 34 is restrained by the tank band 16, and a deformation | transformation (elongation deformation | transformation) of the flange part 22 is suppressed.

さらに、燃料タンク取付構造１０では、タンクバンド１６がタンク上面１４Ａとフロアパネル１８の下面１８Ａとの間にクッション材２０を介した状態で燃料タンク１４を車両下方側から支持して燃料タンク１４をフロアパネル１８に対して強固に拘束するため、フランジ部２２に作用する燃料タンク１４の荷重が低減される。このため、防振ゴム４２のへたりを抑えるためにゴム硬度を高めたりする必要がなく、燃料タンク１４内の燃料の流動音が車体１２に伝達するのを効果的に低減できる範囲で防振ゴム４２の硬度を設定することができる。これにより、燃料タンク１４内の燃料の流動音が車体１２へ伝達するのを低減する効果が得やすくなる。   Further, in the fuel tank mounting structure 10, the fuel tank 14 is supported from the vehicle lower side with the tank band 16 interposed between the tank upper surface 14 </ b> A and the lower surface 18 </ b> A of the floor panel 18 with the cushion material 20 interposed therebetween. Since the floor panel 18 is firmly restrained, the load of the fuel tank 14 acting on the flange portion 22 is reduced. Therefore, it is not necessary to increase the rubber hardness in order to suppress the sag of the anti-vibration rubber 42, and the anti-vibration is within a range in which it is possible to effectively reduce the transmission sound of the fuel in the fuel tank 14 to the vehicle body 12. The hardness of the rubber 42 can be set. As a result, the effect of reducing the transmission sound of the fuel in the fuel tank 14 to the vehicle body 12 can be easily obtained.

またさらに、本実施形態の燃料タンク取付構造１０では、フランジ部２２をタンク前面１４Ｂに車幅方向に間隔をあけて２つ設けていることから、２つのフランジ部２２と２つのタンクバンド１６の車体固定部１６Ｂをボルト２４による共締めによって車体１２にそれぞれ固定することで、燃料タンク１４の位置決めを容易に行うことができる。なお、本発明は、上記構成に限定されず、フランジ部２２は、燃料タンク１４のタンク前面１４Ｂ以外に設けてもよい。   Furthermore, in the fuel tank mounting structure 10 of the present embodiment, since the two flange portions 22 are provided on the tank front surface 14B with an interval in the vehicle width direction, the two flange portions 22 and the two tank bands 16 are provided. By fixing the vehicle body fixing portion 16B to the vehicle body 12 by fastening together with the bolts 24, the fuel tank 14 can be easily positioned. In addition, this invention is not limited to the said structure, You may provide the flange part 22 other than the tank front surface 14B of the fuel tank 14. FIG.

前述の実施形態では、燃料タンク１４を樹脂製としているが、本発明はこの構成に限定されず、燃料タンク１４は、金属製としてもよい。   In the above-described embodiment, the fuel tank 14 is made of resin, but the present invention is not limited to this configuration, and the fuel tank 14 may be made of metal.

また、前述の実施形態では、防振装置３４を介してフランジ部２２と車体固定部１６Ｂとを共締めによって車体１２に締結固定する構成としているが、本発明はこの構成に限定されない。例えば、防振装置３４を用いずに、フランジ部２２と車体固定部１６Ｂとを共締めによって車体１２に締結固定する構成としてもよい。   In the above-described embodiment, the flange portion 22 and the vehicle body fixing portion 16B are fastened and fixed to the vehicle body 12 through the vibration isolator 34, but the present invention is not limited to this configuration. For example, without using the vibration isolator 34, the flange portion 22 and the vehicle body fixing portion 16B may be fastened and fixed to the vehicle body 12 together.

以上、本発明の一実施形態について説明したが、本発明は、上記に限定されるものでなく、その主旨を逸脱しない範囲内において上記以外にも種々変形して実施することが可能であることは勿論である。   Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and various modifications other than the above can be implemented without departing from the spirit of the present invention. Of course.
