A fluid-filled cylindrical elastic mount which includes radially spaced-apart inner and outer sleeves, and an elastic body interposed between the inner and outer sleeves for elastical connection thereof. The elastic body has diametrically opposite fluid chambers containing a highly viscous fluid, and at least one fluid passage which communicates with the fluid chambers. The outer sleeve has at least one inlet through which the highly viscous fluid is injected into the mount. Each of the inlets is formed in a portion of the outer sleeve which defines the corresponding fluid passage, and is closed by a sealing member fixed to the outer sleeve. The elastic mount further includes a pair of restricting protrusions which are respectively formed in the fluid chambers to protrude from the inner sleeve toward the outer sleeve in radially opposite directions, such that each protrusion has a radial end face which cooperates with the outer sleeve to define a restricted portion which has a predetermined radial dimension.
