PROBLEM TO BE SOLVED: To provide a vibration isolation device capable of improving the durability of a vibration isolation base while differentiating spring constants in two directions perpendicular to the axis line.SOLUTION: A joint part to the outer periphery of which the vibration isolation base is joined includes a chamfered portion formed by cutting the corner where a flange part and the joint part are communicated, a base portion linked to the chamfered portion in its axial direction, and a front end portion linked to the base portion in its axial direction. Compared to the area of the first projection surface of at least the front end portion of the joint part projected in a first direction perpendicular to the axis line, the area of the second projection surface of it projected to a second direction perpendicular to the axis line and the first direction is set larger.SELECTED DRAWING: Figure 2
【課題】軸線と直交する2方向のばね定数は異ならせつつ、防振基体の耐久性を向上できる防振装置を提供すること。【解決手段】防振基体が外周に接合される接合部は、フランジ部と接合部とが連絡する隅を取った面取部と、面取部の軸線方向に連接される基部と、基部の軸線方向に連接される先端部と、を備えている。接合部は、少なくとも先端部において、軸線と直交する第1方向へ投影した第1の投影面の面積よりも、軸線および第1方向と直交する第2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。【選択図】図2
