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