VIBRATION ISOLATOR
Document Type and Number:
Japanese Patent JP2020012533
Kind Code:
A
Abstract:
To provide a vibration isolator of a novel structure capable of reducing distortion of a body rubber elastic body and improving durability with respect to input in the same inclined direction as a tapered outer peripheral surface of the body rubber elastic body.SOLUTION: In a vibration isolator 10, an inner fitting member 12 enters inward in an axial direction from a small diameter side end part 48 of a body rubber elastic body 16 having a tapered outer peripheral surface 60 and is fastened to the body rubber elastic body 16, and an outer fitting member 14 is fastened with an outer peripheral surface of a large diameter side end part 50 of the body rubber elastic body 16. An axial direction intermediate part entering into the body rubber elastic body 16 in the inner fitting member 12 is provided with a circumferential groove-shaped recess 36 which opens on the outer peripheral surface and extends in a circumferential direction. On both sides in the axial direction of the circumferential groove-shaped recess 36, an outer peripheral projection 40 of a larger diameter than the circumferential groove-shaped recess 36 is provided on both sides in the axial direction, and the outer peripheral surface of the circumferential groove shape recess 36 and the inner peripheral surface of the outer fitting member 14 are coupled by the body rubber elastic body 16 of a solid structure in the same inclined direction as the tapered outer peripheral surface 60.SELECTED DRAWING: Figure 1
