Description
前記弾性体は、軸方向に貫通するすぐり部を有し、
前記すぐり部は、軸直方向断面視で、前記内筒側の輪郭線部分が、前記内筒に近接する第1輪郭線部分、前記第1輪郭線部分から前記外筒に向かって延在する第2輪郭線部分、および、前記第2輪郭線部分から当該第2輪郭線部分を挟んで前記第1輪郭線部分と反対側に延在する第3輪郭線部分を有し、
前記第1輪郭線部分と前記第2輪郭線部分とが繋がる部分は、自重方向において、前記第2輪郭線部分と前記第3輪郭線部分とが繋がる部分に対してずれた位置に配置されていることを特徴とする。
本発明に係る防振装置によれば、弾性体の内筒周りのせん断応力が軽減されることにより、耐久性を向上させることができる。
この場合、耐久性を更に向上させることができる。
