摘要： 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).

摘要： The present invention is a vibration damping device (1, 2) that includes an external member (11, 21) attached to one of a vibration-generating portion and a vibration-receiving portion; a tubular member (40) attached to the other of the vibration-generating portion and the vibration-receiving portion; and an elastic body (30) which connects the external member (11, 21) and the tubular member (40). The external member (11, 21) includes a frame-like member (11, 21) having a rectangular shape when viewed from the top. In the elastic body (30), a long-side portion (32a) forming a long side of a rectangular shape when viewed from the top adheres to an inner circumferential surface of the long-side portion (12a, 12b) of the frame-like member (11, 21), and a short-side portion (32b) forming a short side of the rectangular shape when viewed from the top comes into contact with the external member (11, 21) in a long-side direction (X) in which the long-side portion (12a, 12b) extends when viewed from the top, in a non-adhering state.
