Abstract: A vibration-damping device includes a housing having a cylindrical mounting hole therein and a vibration-damping member provided in the mounting hole. The vibration-damping member includes an outer cylinder fitted into the mounting hole, an inner cylinder provided in the outer cylinder, and a rubber elastic body inserted between the outer cylinder and the inner cylinder. The rubber elastic body is formed with a bore penetrating in an axial direction thereof and a stopper protruding from a radially-inner wall surface thereof for the bore. The housing is formed with a receiving part which faces the stopper, in a radial direction of the mounting hole, across a gap.

Abstract: 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.

Abstract: A vibration proofing device (10) includes an insulator (50) interposed between a first attaching member (30) and a second attaching member (40), and is disposed in an internal space (95) of a second bracket (90). The first attaching member (30) is formed to have two side walls (33, 33) parallel to each other to face the inner face of the second bracket (90). The second attaching member (40) is a tubular member having an opening (41a) passing therethrough in an upper-lower direction. At least one of side edge portions of each side wall (33) is disposed outside the opening (41a) of the second attaching member (40). Each side wall (33) is provided on an outer face thereof with a stopper (51) made of an elastic material. With this configuration, it is possible to sufficiently absorb an impact shock resulting from the stopper (51) hitting the second bracket (90).

Abstract: An anti-vibration device is provided with: an anti-vibration device body, in which an insulator is disposed between a first attachment member and a second attachment member; and a bracket, which has opposing wall portions and to which the anti-vibration device body is fixed by press-fitting via the second attachment member between the wall portions. The second attachment member is provided with interlocking portions that interlock with the wall portions and restrain the anti-vibration device body from moving in the direction opposite the press-fitting direction when the anti-vibration device body is press-fitted to the bracket. Each of the interlocking portions is configured so as to have an arm part extending in the direction opposite the press-fitting direction, and a hook part provided to the extension-direction end of the arm part and caused to interlock with a to-be-interlocked part of one of the wall portions.

Abstract: The present invention provides a vibration-damping device having an inner cylinder, an outer cylinder arranged at a distance on an outer diameter side of the inner cylinder, a rubber elastic body interposed between the inner cylinder and the outer cylinder for elastically coupling the inner cylinder and the outer cylinder, and an intermediate plate embedded in the rubber elastic body. A plurality of cutout parts positioned on both end sides in the axial direction of the outer cylinder for joining an inner side rubber elastic body and an outer side rubber elastic body are formed in the intermediate plate. At least one of the cutout parts is arranged to overlap on an area that is sandwiched between two parallel imaginary planes that are adjacent to the outer peripheral surface of the inner cylinder.
