Abstract: An anti-vibration device (1) includes a covering member (17), arranged between an inner attachment member (11) and an outer cylinder (12), that covers, from outside in the radial direction, the area between a pair of middle elastic bodies (32) adjacent to each other in the circumferential direction, and defines a pair of liquid chambers (14a, 14b) between the inner attachment member and the covering member. An orifice passage (19) connecting each liquid chamber is formed between the covering member and the outer cylinder. A first connecting aperture (18) and a second connecting aperture (20) that separately connect each liquid chamber and the orifice passage are formed in the covering member. An injection hole (12a) formed in the outer cylinder and sealed by a sealing material (16) opens toward at least one of the first connecting aperture and the second connecting aperture.

Abstract: A floor portion (34) is formed to be inflected to a radial direction inner side from a lower end portion of a channel outer tube portion (32), and is disposed apart from and opposing a flange portion (24) at an outer periphery side of a tube portion (22) of a dividing member (20). The floor portion (34) is disposed within the tube portion (22) in an axial direction S, that is, so as to overlap with the tube portion (22) when viewed from a radial direction. A diaphragm (50) in the form of an elastic film is adhered by vulcanization to a restriction channel member (30) so as to cover an aperture in a lower side of the restriction channel member (30). A seal portion (56) is vulcanization-formed integrally with the diaphragm (50), so as to cover an inner periphery face of a channel inner tube portion (36) of the restriction channel member (30).

Abstract: A strut mount disposed between a body panel and a strut rod comprises an outer member connected to the body panel, an inner member connected to the strut rod, an elastically deformable elastomer disposed so as to connect the outer member and the inner member, and a spring bearing portion formed by extending a part of the outer member outward in a flange form so as to support an end portion of a spring disposed along with the strut rod.

Abstract: A partitioning member is disposed within an outer cylinder metal fitting. A space which is defined by the partitioning member and an elastic body forms a main liquid chamber. The main liquid chamber and a first auxiliary liquid chamber are disposed with the partitioning member therebetween. A shake orifice and an idle orifice are formed at the partitioning member and the idle orifice is opened and closed by a rotor. A second diaphragm is disposed at the first auxiliary liquid chamber side and a clearance between the second diaphragm and the lower surface of the partitioning member forms a second auxiliary liquid chamber. When shake vibration which is low frequency vibration is generated, the vibration is damped and absorbed by the shake orifice. When idle vibration is generated, the idle orifice is opened and the high frequency vibration is absorbed.
