PROBLEM TO BE SOLVED: To prevent wobble/resonance generated on a stay bolt and a support, by employing a structural technique and devising to a conventional support, secure silence and comfort in a vehicle and achieve attenuation of wobble and oscillation due to self excited oscillation.SOLUTION: A support C in which a stay bolt is elastically supported and outside dimension of a body part becomes thicker from a lower side toward an upper side, namely a tapered shape, is provided on a bracket so that the support can be inserted and removed freely, and two-piece structure elastic piece is provided on a side surface of the body part 3, and the elastic piece has oscillation attenuation means in different directions. By inclination of a shell (main body), easiness of insertion and removal of the support into/from the bracket and improvement of compatibility with the bracket can be achieved.
【課題】従来のサポートに、構造的な技術と工夫を行うことで、ステーとサポートとで発生するガタ/共振を防止し、車内の静寂、快適性を確保し、かつ自励振動によるガタと振動減衰を図る。【解決手段】ステーを弾性的に支持し、本体部の外側寸法を、下方から上方に向かって太くしたテーパー形成のサポートCにおいて、サポートをブラケットに抜差し自在に設け、かつ本体部3の側面に二枚構造の弾性片を設け、弾性片に異なる方向の振動衰退手段を設けるサポートとし、胴体(本体部)の傾斜化でブラケットへの抜差し容易化と、ブラケットとの相性の向上化、が達成できる。【選択図】図2−1
