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 allows a sufficient pre-compression to be applied to a rubber member without impairing the retaining force for the rubber member, thereby achieving improved durability of the rubber member. A pre-compression member (4) has an outer diameter that is smaller in the distal end side than in the proximal end side, and is press-fitted into the inner peripheral surface of an inner tube member (1).

Abstract: An outer tube (11) of a vibration-damping device (10) is split into a first outer tube member (21) at a first end along the direction of an axis (O), and a second outer tube member (22) at a second end. The second end of the first outer tube member (21) in the direction of the axis (O), and the first end of the second outer tube member (22) in the direction of the axis (O) overlap each other in a radial direction of the outer tube (11) with the second rubber elastic body therebetween (23). Through this configuration, the generation of a noise from the vibration-damping device can be suppressed.
