- インジェクタの円筒状のハウジングの外周に設けられ、当該ハウジングの外周面と前記インジェクタの先端側が挿入されたインジェクタ取付孔との間に介在する環状の制振インシュレータであって、
環状に形成されたコイルスプリングの内周に弾性材料を埋め込み、かつ、外周を当該弾性材料で包囲し、さらにその外周を2枚の外装プレートで前記インジェクタの先端側である下側および前記インジェクタの基端側である上側から包み込み、
下側の前記外装プレートは、前記コイルスプリングの下側において前記コイルスプリングの環状に対する径方向に延びた第1平坦部と、前記第1平坦部における前記径方向の外側の端部から前記環状に対する軸心方向の上側に曲がって前記軸心方向に延びた側面部とを有し、
上側の前記外装プレートは、前記コイルスプリングの上側において前記径方向に延びた第2平坦部と、前記第2平坦部における前記径方向の内側の端部から前記コイルスプリングの外周に沿って前記軸心方向の下側に湾曲した湾曲部と、前記第2平坦部における前記径方向の外側の端部から前記軸心方向の下側に折れ曲がった折代部とを有し、
上側の前記外装プレートの前記折代部の下端部が外側から下側の前記外装プレートの前側面部の上端部と重なり合う一方で、上側の前記外装プレートの前記湾曲部の下端部と下側の前記外装プレートの前記第1平坦部における前記径方向に内側の先端部との間に隙間が形成され、
前記インジェクタのハウジングは、段付き円筒形状を有しており、その段差部にテーパ面が設けられ、
前記制振インシュレータの前記テーパ面との接触面は、アール形状をなしていることを特徴とする制振インシュレータ。
