PROBLEM TO BE SOLVED: To provide a vibration-proofing device capable of assuring durability while spring constants in two directions crossing at a right angle with an axial direction being made different.SOLUTION: A first fixture 20 is made in such a way that a fastening part 30 having a small-diameter side end part 51 of a vibration-proofing substrate 50 fastened over its circumferential direction shows that an area of the second projecting plane projected in the second direction (a direction Y) is set larger than an area of the first projecting plane projected in the first direction (a direction X). With this arrangement, the spring constant in the first direction is set lower than that in the second direction. Since it is not necessary to let a segment of the vibration-proofing substrate 50 corresponding to the first direction thinner than a segment of the vibration-proofing substrate corresponding to the second direction, it is possible to assure its durability while making spring constants in two directions crossing at a right angle with an axial direction (a direction Z) different to each other.SELECTED DRAWING: Figure 5
【課題】軸方向と直交する2方向のばね定数を異ならせつつ耐久性を確保できる防振装置を提供すること。【解決手段】第1取付具20は、防振基体50の小径側端部51が周方向に亘って固着される固着部30が、第1方向(X方向)へ投影した第1の投影面の面積より、第2方向(Y方向)へ投影した第2の投影面の面積が大きく設定される。これにより、第1方向のばね定数が第2方向のばね定数より小さく設定される。防振基体50の第1方向に対応する部位を第2方向に対応する部位より薄くする必要がないので、軸方向(Z方向)と直交する2方向のばね定数を異ならせつつ耐久性を確保できる。【選択図】図5
