Then, the 1st installation component 12 and the 2nd installation component 14 are configured at the top of the 2nd installation component 14 coaxially, and above-mentioned 1st installation component 12 and the 2nd installation component 14 are linked by the mutual elasticity of main rubber elastomer 16.Main rubber elastomer 16 is the roughly round table-like of thick-wall and large-diameter, the end of its smaller diameter side is stacked merging with the fixed bonding portion 18 of the 1st installation component 12 and lip part 22 and cures bonding, and the end of larger diameter side is stacked merging with the minor diameter cylinder portion 28 of the 2nd installation component 14 and the upper end portion in major diameter cylinder portion 30 cures bonding.In addition, main rubber elastomer 16 is formed as the integrated vulcanizing formed article with the 1st installation component 12 and the 2nd installation component 14.
And, main rubber elastomer 16 is formed major diameter recess 32.Major diameter recess 32 is recesses of the larger diameter side end opening at main rubber elastomer 16, and opening side is large diameter, reverse roughly mortar shape.
In addition, main rubber elastomer 16 forms limited location blob of viscose 34.Spacing blob of viscose 34 is set to give prominence to upward from the smaller diameter side end of main rubber elastomer 16, and the outer circumferential face bonding by Vulcanization of lip part 22 at upper surface place and the 1st installation component 12.
In addition, the integrated vulcanizing products formed of main rubber elastomer 16 is provided with orifice element 36.Orifice element 36 is the components in the roughly hard of circular plate shape, is formed by the synthetic resin material etc. of the metallic material such as iron, aluminum alloy, hard.And, orifice element 36 is formed the central indentation 38 of the circle of the upper surface upper shed at radial middle body, expands the volume of air chamber 44 described later.In addition, the radial middle body of orifice element 36 forms the recess of the circle corresponding with central indentation 38 by opening on the lower surface, thus becomes the thin thin-walled of wall ratio outer peripheral portion.
In addition, the outer peripheral portion formed in the mode of heavy wall of orifice element 36 is formed with all grooves 40.Week, groove 40 was outer circumferential face upper shed at orifice element 36 and groove circumferentially, in the present embodiment in the shape of a spiral and circumferentially less than the length of two weeks.
To construct as above in open part that the orifice element 36 made is inserted on the downside of the 2nd installation component 14, and support by the 2nd installation component 14.Namely, orifice element 36 by be pressed into from below in major diameter cylinder portion 30 except fixing in the part except bonding fixed bonding part with main rubber elastomer 16, the outer circumferential face of orifice element 36 is fixed with the state directly superimposed with the inner peripheral surface of the 2nd installation component 14 and is bonded on the 2nd installation component 14.And, after being pressed into the 2nd installation component 14 by orifice element 36, undergauge processing is carried out to the underpart of the 2nd installation component 14, thus be formed with the conic clamp bonding part 42 of reduced diameter downward.Thus, by the abutting to conic clamp bonding part 42, orifice element 36 displacement downwards can be limited, prevent orifice element 36 from deviating from from the 2nd installation component 14.
In addition, also can after the major diameter cylinder portion 30 relative to the 2nd installation component 14 inserts orifice element 36 from below, 2nd installation component 14 is implemented each to undergauge processing such as undergauges, thus the inner peripheral surface of the 2nd installation component 14 is crimped mutually with the outer circumferential face of orifice element 36, orifice element 36 setting-in is fixed on the 2nd installation component 14.In this case, also conic clamp bonding part 42 can be formed while orifice element 36 is fixed on the 2nd installation component 14.
