PURPOSE: To provide a vibration control device which has such a structure that each of an elastic material of an elastic body for absorbing vibration and the elastic material forming the elastic film of sub fluid room is selected most adequately as well as forming a long orifice, in a vibration proof device. CONSTITUTION: The first resin influx preventing cover 32 in which diaphragms 36L, 36R are vulcanizedly-attached is fittedly-attached on a narrow width groove 26 of an elastic body 16, and the second resin influx preventing cover 38 and a controlling pathway forming cover 56 are covered in the outer circumference thereof. An outer cylinder 12 is molded on the outside of the cover 56, by mounting this in a mold and injecting a synthetic resin. Most adequate materials can be used respectively for the elastic body 16 and the diaphragms 36L, 36R because those are separate bodies, and long life of the vibration control device 10 with securing ozone-proof and settling-proof properties is ensured, by using butyl gum or the like as the diaphragms 36L, 36R. |
