- the end portions of the fourth rib 16d are flush with each other in the positive direction of the y-axis, and the other side end portion of the central portion 62, the end portion of the fifth rib 16e of the first extending portion 64a, and The ends of the sixth ribs 16f of the second extension part 64b are flush with each other in the negative direction of the y-axis, but the distance between them and the axis C is a predetermined amount than the inner diameter of the coil spring 20. It is set so large.
- the vibration damper 60 when the vibration damper 60 is inserted in the coil spring 20, the convex portion 12 a provided in the central portion 62 protrudes from the central portion 62 by a predetermined amount.
- the anti-vibration damper 60 is positioned with respect to the coil spring 20 by being locked between predetermined adjacent wire rods 20 a and 20 b of the coil spring 20.
- the center portion 62 is provided with a seventh rib 18 on its inner peripheral surface as in the first embodiment.
- the seventh rib 18 extends in an X shape while observing in the radial direction of the central portion 62 and overlaps with the convex portion 12a, and each end portion thereof extends in the first extension.
- the third rib 16c and the fifth rib 16e of the existing portion 64a and the fourth rib 16d and the sixth rib 16f of the second extending portion 64b are reached.
- the central portion 62 is a triangular cylindrical member, and the first extending portion 64a and the second extending portion 64b are each a truncated triangular pyramidal cylindrical member.
- the position of the apex P1 is movable so as to be inscribed in the arc CR set so as to have a predetermined insertion allowance with respect to the inner peripheral portion of the coil spring 20, and the vibration isolating having a more polygonal shape
- apexes P2, P3 and the like that are inscribed in the arc CR can be appropriately set.
- the central portion is a rectangular tubular member and the first extending portion a and the second extending portion are truncated pyramidal cylindrical members.
- the shape, arrangement, number, and the like of the members are not limited to the above-described embodiments, and the constituent elements thereof are appropriately replaced with those having the same operational effects, and the gist of the invention is not deviated. Of course, it can be appropriately changed within the range.
- the vibration damping damper of the present invention when inserting along the inner peripheral portion of the coil spring, the positioning is accurately performed in a state where the contact area is reduced and no twist or twist occurs. It is possible to provide an anti-vibration damper for coil springs that can be assembled so that it will not fall off, and can produce the desired anti-vibration characteristics while suppressing the occurrence of abnormal noise. It is expected that it can be applied to
