PROBLEM TO BE SOLVED: To provide a fluid filled cylindrical mount having improved construction for developing further more vibration proofing effects based on the flowing operation of fluid by advantageously securing the flow amount of the fluid through an orifice passage during vibration input in the axial direction. SOLUTION: A partition wall rubber elastic body 50 connecting an inner shaft member 12 to an outer cylindrical member 14 consists of a cylindrical portion 52 extending axially from an intermediate portion between the radially opposed faces of the inner shaft member 12 and the outer cylindrical member 14 and a circular dome portion 54 extending radially inward from an axial front end portion of the cylindrical portion 52 on the side of the rubber elastic body 16 in an approximately arcuate shape. The position of the inner shaft member 12 to be fixed to the outer cylindrical member 14 at both axial ends of the partition wall rubber elastic body 50 is set so that axial tensile deformation is caused in a pre-mounted state in which no initial load occurs and axial compressive deformation is caused in a mounted state in which an initial load occurs.
