An antivibration device includes a bracket fixed to an antivibration connection target member. A positioning member attached to an attachment hole of the bracket includes a positioning protruding portion inserted into a positioning hole of the antivibration connection target member and positioning the bracket; and a cylindrical attachment portion protruding from the positioning protruding portion and inserted into the attachment hole. The attachment portion has a locking claw protruding toward the outer periphery. The positioning member is positioned with respect to the bracket by sandwiching a peripheral edge portion of the attachment hole between the positioning protruding portion and the locking claw. The peripheral edge portion of the attachment hole has a protrusion that protrudes in the penetrating direction of the attachment hole to adjust and set the thickness of the peripheral edge portion.

A vibration proofing device includes a bracket having an internal space, and a vibration proofing member inserted into the internal space. The internal space is open on an outer surface of the bracket. At least a pair of facing-each-other surfaces, against which the vibration proofing member is pressed, is formed in an inner surface of the bracket. A distance between the pair of the facing-each-other surfaces on a far side in an insertion direction of the vibration proofing member is the same, in at least some regions of the bracket, as that on a near side in the insertion direction. This provides the vibration proofing device and the bracket to allow for compactly configuring the device as a whole, while sufficiently securing a retaining force between the bracket and the vibration proofing member.

A anti-vibration device (1) includes a bracket (4) made of a synthetic resin and cylindrical metal fittings for fastening (5), where the bracket (4) and the metal fittings for fastening (5) are integrally formed. A vibration input position (P) is a position that does not coincide with a virtual line (L1) passing through central axes (O5) of a through holes (5h) of two metal fittings for fastening (5) in a planar view; the metal fitting for fastening (5) has a flange portion (51); and the flange portion 51 has a first outermost peripheral edge (51a) and a second outermost peripheral edge (51b), where a length (L51a) to the first outermost peripheral edge (51a) is longer than a length (L51b) to the second outermost peripheral edge (51b) based on the center axis (O5) of the through hole (5h).

An isolator assembly includes a bracket, a first isolator connected to the bracket, a second isolator connected to the bracket, and/or a mass connected to the bracket via the first isolator and the second isolator. The first isolator and the second isolator may include a plurality of legs. The first isolator may include a first radial flange and a second radial flange. The first radial flange and the second radial flange may be axially spaced from each other. An outer diameter of the first radial flange may be larger than an outer diameter of the second radial flange. A distance between the first radial flange and the second radial flange may correspond to a thickness of the bracket.

A vehicle body mount assembly includes an inner metal sleeve, a polymer mounting bracket with a damper opening oriented coaxially with the inner metal sleeve, an elastomeric damper disposed within the damper opening between the inner metal sleeve and the polymer mounting bracket, at least one fastening element embedded in and extending from the polymer mounting bracket, and a ferrule disposed at least partially within the inner metal sleeve. A polymer outer sleeve can be included and disposed between elastomeric damper and the polymer mounting bracket. Also, the at least one fastening element can be a stud bolt with a head embedded in the polymer mounting bracket, a nut embedded in the polymer mounting bracket, or a metal sleeve configured for a bolt to extend therethrough embedded in the polymer mounting bracket.

A vibration-damping device body (10) is provided that includes a first mounting member (11) mounted on one of a vibration-generating portion and a vibration-receiving portion via a bracket (2), a second mounting member (12) mounted on the other of the vibration-generating portion and the vibration-receiving portion, and an elastic body (13) connecting the first mounting member (11) and the second mounting member (12). The first mounting member (11) is fitted into a fitting hole (2a) formed in the bracket (2).
