LIQUID-SEALED VIBRATION CONTROL MOUNT

摘要

PURPOSE:To cause an air chamber to form a closed type by a method wherein the protection cover of the diaphragm of a liquid-sealed vibration insulation mount is reliably fixed with high sealing ability so as to prevent the occurrence of a slack and a backlash. CONSTITUTION:A vibration insulation base body 3 is mounted in a seal state in one opening part 2 of a body fitment l and a diaphragm 5 in the other opening part 4 to form a liquid chamber 6. The liquid chamber 6 is partitioned into a plurality of liquid chambers 6a and 6a, intercommunicated through an orifice 7, by means of a partition member 8. The protection cover 9 of the diaphragm 5 is attached in an opening part 4 in which the diaphragm 5 is mounted. The protection cover 9 has a peripheral edge part 9a fitted in the outer periphery of the opening part 4 through a rubber part 5a, and an extension part 21 from the body fitment l along the fitting-in part is securely caulked throughout a whole periphery in such a manner to fasten the peripheral edge part 9a.
