- the tool hole 116 it is essential that at least the tool hole 116 is exposed to the outside through the access hole 86.
- the number and shape of the pipe holding portions formed on the base member 11 and the lid member 12 can be arbitrarily set.
- maintains is not restricted to a filler pipe etc., Various pipes may be sufficient.
- the pipe clamp can hold not only the pipe but also a solid wire or a harness.
- the leg piece portion 16 is engaged with the locking hole 206, but the leg piece portion 16 is engaged with the locking hole 206.

Abstract
Description
図1~図4に示すように、パイプクランプ(クランプ)10は、それぞれ樹脂材料から形成されたベース部材(第1部材)11と、ベース部材11に回動可能に支持された蓋部材(第2部材)12と、ベース部材11に保持されたピン部材13とを主要構成要素として有している。パイプクランプ10は、ベース部材11と蓋部材12との間に管状体であるフィラーパイプ200およびブリーザパイプ201を挟持し、ベース部材11が支持部材としての車体パネル205表面に取り付けられることによって、フィラーパイプ200およびブリーザパイプ201を車体パネル205に固定する。
図1~図4に示すように、ベース部材11は、左右方向に延在する本体部15と、本体部15の下部より下方へと突設された脚片部16と、本体部15の上部に凹設された第1および第2パイプ保持部17,18と、本体部15の左端部に設けられたヒンジ軸部19と、蓋部材12との係合部として本体部15の上部に形成された2つの連結孔20および4つの連結爪21とを備えている。
図1~図4に示すように、蓋部材12は、左右方向に延在する本体部71と、本体部71の右端部に形成されたヒンジ軸受部72と、本体部71の上部に凹設された第3および第4パイプ保持部73,74と、ベース部材11との係合部として本体部71の上部に形成された2つの連結片75および2つの連結爪76とを備えている。
図5に示すように、ピン部材13は、円柱状の大径軸部101と、大径軸部101の一端に同軸に設けられた大径軸部101よりも小径の小径軸部102と、大径軸部101の他端側に設けられたフランジ部103とを備えている。小径軸部102の外径は、ピン孔25の下半部27の内径よりも小さく形成されている。大径軸部101の外径は、ピン孔25の上半部26の内径よりも小さく、かつ下半部27の内径よりも大きく形成されている。フランジ部103の外径は、上半部26およびボス部34の内径よりも大きく、かつアクセス孔86の内径よりも小さく形成されている。
次に、上述したパイプクランプ10を用いて、フィラーパイプ200およびブリーザパイプ201を車体パネル205に取り付ける方法およびその取付構造について説明する。フィラーパイプ200は、自動車の給油口と燃料タンクとを接続する管であり、その断面形状は円形が変形した扁平形状となっている。ブリーザパイプ201は、給油時の燃料タンク内のガス抜きを行うためにフィラーパイプ200と概ね平行に設けられる管であって、その断面は円形状となっている。車体パネル205は、平板上のパネルであって、円形状の係止孔206が形成されている。
第2実施形態に係るパイプクランプ300は、蓋部材12にピン孔25および脚片部16が設けられている点で第1実施形態と相違する。第2実施形態について、第1実施形態と同様の構成については、同一の符号を付して説明を省略する。
