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 |
