PROBLEM TO BE SOLVED: To improve the manufacturing workability in a fluid sealed type cylindrical vibration control device for respectively forming a main liquid chamber for receiving vibration, a first sub-liquid chamber having the large volume communicated with the main liquid chamber via an orifice passage for a low frequency and a second sub-liquid chamber having the small volume communicated with the main liquid chamber via an orifice passage for a high frequency. SOLUTION: An adjacent opening edge part 46 of a first sub-liquid chamber 78 and a second sub-liquid chamber 80 is held to be reinforced by an end surface of an orifice member 52 by allowing the orifice member 52 to abut to the adjacent opening edge part without using a metallic sleeve 18 to thereby form an object fluid sealed type cylindrical vibration control device by using a handling performance-improved intermediate sleeve formed in a mutually symmetrical shape on both sides for sandwiching a radial directional line being the main vibration input direction. |
