Description
取付部材は、インジェクタの外周面に当接する剛体からなり、ベース部と、
ベース部に設けられ、外周面において大径部と小径部との間となる段差部又は台座部のいずれか一方に当接する接触部と、
ベース部に対して接触部とは反対側に設けられ、接触部の接触していない段差部又は台座部のいずれかに向かって突出した壁部と、
を有し、
接触部とは反対側の面に当接し、且つ、接触部の接触していない段差部又は台座部のいずれかに当接する環状の弾性部材が設けられ、
壁部の外周径は、ベース部の外周径よりも小さく形成されると共に、ベース部には径方向に切り欠かれた切欠部を有し、切欠部の幅寸法は、大径部の外周径よりも小さく、且つ、小径部の外周径よりも大きく設定されることを特徴とする。
