Liquid-filled type vibration absorbing device

A liquid-filled type vibration absorbing device in which a vibration absorbing base made of a rubbery elastic member is interposed between a holding cylinder opened at top and bottom and part of a lower mounting metal fixture, and an upper mounting metal fixture of a thick cylindrical shape having an axis perpendicular to the axis of the device, and in which there are arranged in said holding cylinder a diaphragm made of a rubber film and directly facing the vibration absorbing base, and a partition member for partitioning the space between said vibration absorbing base and said diaphragm into two compartments, thereby to form two liquid chambers communicating with each other through an orifice, comprising:

• an annular member having a flanged upper portion and a cylindrical lower portion and fixed on the outer circumference of the lower portion of said vibration absorbing base;
• and
• an intermediate cylinder joined to said annular member,
• wherein said diaphragm is attached to the lower end portion of said intermediate cylinder whereas the partition member is fitted in the inner circumference of the intermediate cylinder,
• wherein said intermediate cylinder is fitted at its upper portion in the cylindrical lower portion of said annular member and is caulked and fixed at the outer edge portion of its upper end to the flanged upper portion of said annular member, thereby to form the liquid chambers individually between said partition member and both said vibration absorbing base and said diaphragm and to cause the two liquid chambers to communicate with each other through the orifice formed in the partition member, and
• wherein said intermediate cylinder is press-fitted in said holding cylinder.
