PROBLEM TO BE SOLVED: To increase the static spring constant without increasing the dynamic spring constant, to reduce the flexible deformation of a vibration proof base, particularly that downward, to improve the durability by reducing the creep amount by the flexible deformation, and to reduce the influence to the stopper clearance. SOLUTION: In a two chamber liquid seal-type flexible mount, a cylindrical hardware 2 and a fitting 9 are connected through a vibration proof base 3 of a rubber elastic material, a diaphragm 4 of a rubber film, and a partition member 5 located inside of the diaphragm are respectively fixed at an opening side in opposition to the vibration proof base, of the cylindrical hardware 2 in the sealed condition, the inner chamber between the vibration proof base 3 and the diaphragm 4, has the partition structure formed by two liquid chambers 7, 8, and the both liquid chambers 7, 8 are connected by an orifice path 6 installed on the partition member 5. A step face 3a of a peripheral part of the inner face of the vibration proof base 3, and that 5a of a peripheral part of a side face in opposition to the vibration proof base 3, of the partition member 5, are kept into contact with each other without adhesion, to prevent the downward flexible deformation of the vibration proof base 3. |
