PURPOSE:To obtain a vibration control device with which flowing is liquid into a sub-liquid chamber is not prevented, and durability of a diaphragm is improved by increasing a volume of an effective air chamber structured by the diaphragm. CONSTITUTION:An opening 15 is formed on a cylindrical body 14 into which an outer cylinder 16 is inserted and fixed, correspondingly to a position of a rectangular 18 formed on the outer cylinder 16. In case that an oscillation amplitude is large, an inner cylinder is largely flexed, and liquid is flowed from a main liquid chamber 42 to a sub-liquid chamber 36. A diaphragm 24 is expanded in a direction o reducing a capacity of an air chamber. The diaphragm is, however, expanded in an inverted form, so that an expansion rate of the diaphragm 24 is not restricted by the cylindrical body 14. As a result, liquid is not prevented from flowing into the sub-liquid chamber 36. The diaphragm 24 is in closely contact with an inner peripheral surface of the cylindrical body 14, being prevented from folded to form a bent portion, so that durability is improved. |
