VIBRATION ISOLATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a vibration isolating device capable of easily reducing a dynamic spring constant in an axially perpendicular, lateral direction such as a front and rear direction and further capable of tuning rigidity without changing vibration isolating property in the vertical direction nor lowering durability. SOLUTION: An inner cylinder metal fitting and an outer cylinder metal fitting are combined by a rubber elastic body arranged between both metal fittings. A hollow part, which holds the inner cylinder metal fitting between the upper and lower sides and which is wider than the outside diameter of the inner cylinder metallic fitting in a circumferential direction, is respectively formed in the rubber elastic body in a perpendicular section against the axial direction. In the vibration isolating device in which both sides of the rubber elastic body between the upper and lower hollow parts support the inner cylinder metallic fitting against the outer cylinder metallic fitting as a supporting arm. A small hollow owing to a non-through hole or through hole in a separated position inward from the outer cylinder metallic fitting in an axial direction is provided in both side portions of the rubber elastic body.
