本考案は、自動車用燃料タンクの給油管におけ
る静電気の帯電防止を目的とする給油管の取付構
造に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a fuel supply pipe mounting structure for the purpose of preventing static electricity from being charged in the fuel supply pipe of a fuel tank for an automobile.
（従来の技術）
給油された燃料は、給油口より給油管を通つて
燃料タンクへ供給されるが、給油の際に燃料の流
れにより静電気が発生し、給油管が帯電すること
がある。そして、給油口付近のガソリン蒸気濃度
がある混合比になつていた場合には、引火するお
それがある。(Prior Art) Refueled fuel is supplied from a fuel filler port to a fuel tank through a fuel supply pipe, but during refueling, static electricity is generated due to the flow of fuel, and the fuel supply pipe may become electrically charged. If the gasoline vapor concentration near the fuel filler port reaches a certain mixing ratio, there is a risk of ignition.
そこで、このような静電気の発生を防止するた
めに給油管をアースする必要があるが、この従来
のアースの取り方の一例を第５図に示す。 Therefore, in order to prevent the generation of static electricity, it is necessary to ground the oil supply pipe, and an example of this conventional method of grounding is shown in FIG.
車体に取付けられるフユエルインレツトボツク
ス１に、給油管２のホルダ部３が複数のボルト４

ツピングネジ８によりフユエルインレツトボツク
ス１に取付けられて、給油管２は車体側にアース
された状態となつている。 A holder part 3 of a fuel supply pipe 2 is attached to a fuel inlet box 1 attached to a vehicle body with a plurality of bolts 4.
It is installed by A crimp terminal 6 to which a ground wire 5 is connected is attached to one of the plurality of bolts 4, and the other crimp terminal 7 is attached to the fuel inlet box 1 with a tapping screw 8, and the fuel inlet box 1 is connected to the fuel supply pipe 2. is grounded to the vehicle body side.
このときのホルダ部３のボルト４による取付け
を第６図に図示する。９はワツシヤ、１０はスプ

付用孔１ａの径がボルト４の径よりも大きいため
に、ボルト４の締付時のかじりによる塗膜の剥
離、及びボルト４と孔１ａの内周との接触が必ず
しも生じないからである。 The attachment of the holder portion 3 using the bolts 4 at this time is illustrated in FIG. 9 is a washer, and 10 is a spring washer. The surface of the fuel inlet box 1 is coated to prevent rust, and because of this coating, it is difficult to connect the holder part 3 and the fuel inlet box 1 by simply tightening the bolts 4.
and are not electrically connected. This is because the diameter of the bolt tightening hole 1a of the fuel inlet box 1 is larger than the diameter of the bolt 4, so the paint film peels off due to galling when the bolt 4 is tightened, and the inside of the bolt 4 and hole 1a may peel off. This is because contact with the surroundings does not necessarily occur.
そこで、ボルト４の代りにタツピングネジを用
いることが考えられるが、この場合は孔１ａに対
応する下孔の径がタツピングネジの径よりも小さ
くなるために、タツピングネジの締付時のかじり
により、ホルダ部３とフユエルインレツトボツク
ス１とはタツピングネジを介して電気的に導通状
態となる。しかし、給油口付近は給油の際の器具
等の衝撃が多い箇所であり、タツピングネジはホ
ルダ部の取付用部材としては締付力が弱く不適当
である。 Therefore, it is possible to use a tapping screw instead of the bolt 4, but in this case, since the diameter of the pilot hole corresponding to the hole 1a is smaller than the diameter of the tapping screw, the holder may be damaged due to galling when the tapping screw is tightened. 3 and the fuel inlet box 1 are electrically connected to each other through the tapping screw. However, the vicinity of the refueling port is a location where there is a lot of impact from instruments and the like during refueling, and the tapping screw has a weak tightening force and is therefore inappropriate as a member for attaching the holder portion.
したがつて、前述のようにアース線５その他の
部材を用いて、給油管２を車体側にアースしてい
たのである。 Therefore, as described above, the fuel supply pipe 2 was grounded to the vehicle body using the ground wire 5 and other members.
（本考案が解決しようとする問題点）
しかしながら、このようなアースの取り方は、
アースのみを目的とした別部材を別個に設けるこ

上の面でも問題がある。さらに、アース線の片側
の接続にはタツピングネジを用いているため、こ
のネジ部分より錆が発生する可能性が大きい等の
問題点もある。(Problem that this invention attempts to solve) However, this method of grounding is
Since a separate member is provided for the sole purpose of grounding, the number of man-hours required increases and there are also problems in terms of appearance. Furthermore, since a tapping screw is used to connect one side of the ground wire, there are problems such as the possibility that rust will occur in this screw portion.

内周に設けられた突起部の先端をネジ部材がかじ
り、突起部表面の塗膜が剥離される。(Function) According to this configuration, when attaching the holder portion of the fuel supply pipe to the vehicle body side with a screw member, the screw member bites the tip of the protrusion provided on the inner periphery of the hole through which the screw member is passed, and the surface of the protrusion The paint film is peeled off.
したがつて、ホルダ部と車体側とはネジ部材を
介して導通状態となるため、給油管における静電
気の帯電を防止することができる。 Therefore, the holder portion and the vehicle body side are electrically connected via the screw member, so that it is possible to prevent static electricity from being charged in the fuel supply pipe.
（実施例）
以下、本考案の実施例を第１図乃至第４図に基

げることとなる。 A spring washer 10, a washer 9, a fuel inlet box 1, a packing 12, and a holder portion 3 are tightened by the head of the bolt 4 and the nut 11. At this time, since the protrusion 1c is bitten by the threaded portion of the bolt 4, the coating film on the tip of the protrusion 1c is peeled off. Therefore, the static electricity generated in the fuel supply pipe 2 escapes to the vehicle body 13 from the holder portion 3 through the nut 11, bolt 4, and projection 1c.

上するのである。 In addition, since the peeling of the coating film at the tip of the protrusion 1c is minimal, the possibility of rust occurrence is smaller compared to the conventional earthing structure using tapping screws, but in order to further increase the rust prevention effect, The washer 9 in FIG. 1 may be made of resin. As a result, waterproofing and
The moisture-proofing effect can be improved, and the rust-preventing effect can also be improved.
