PROBLEM TO BE SOLVED: To realize a long orifice passage with a simple structure and excellent mount manufacturing performance, in a fluid-enclosing type cylindrical mount. SOLUTION: An approximately U-shaped orifice member 44 extending in the circumferential direction with the length larger than the half circumference is so arranged as to extend over fluid chambers 56, 58 by being fitted to an opening part 51 formed between both ends in the circumferential direction from the outside in the direction perpendicular to the axis of a metallic sleeve 18 bonded on the outer peripheral surface of a main body rubber elastic body 16, and an orifice passage 62 for communicating both fluid chambers 56, 58 with each other is formed by inserting an outer cylinder fitting 14 on the outer peripheral side and covering a recessed grove 46 opened on the outer peripheral surface of the orifice member 44 with the outer cylindrical fitting 14. |
