  • Liquid-sealed vibration-proof device
    Patent number: 6655666
    Abstract: A liquid-sealed vibration-proof device capable of avoiding leakage of liquid upon press fitting of an outer cylinder is provided. An intermediate ring interposed between the outer cylinder and an antivibratory base is formed at its outer circumferential surface with two projecting streaks, the one on liquid chambers side being formed with cutouts. When the outer cylinder is press fitted to an attachment opening of a vehicle body, the liquid confined in a space enclosed between both projecting streaks can escape to the liquid chambers, so that liquid never leaks outside.
