PROBLEM TO BE SOLVED: To provide a fluid sealed cylindrical vibration control device advantageously improved in the fitting performance and sealing performance of an orifice member. SOLUTION: The orifice member 24 is formed by fixing or embedding two reinforcing bodies 37 and 37 which are formed of rigid members comprising divided cylindrical parts 50 in an orifice member body 36 which is formed of a cylindrical rubber elastic body and has a cut part 34 and a bending part 46 symmetrically to each other at a predetermined interval in the circumferential direction in a state of pinching the cut part 34 between both circumferential ends of the divided cylinder part 50 and in a state of pinching the bending part 46 between other ends thereof. This orifice member 24 is bent by the bending part 46 and assembled in an intermediate sleeve 28 by being enlarged from a direction at a nearly right angle with respect to the shaft so as to constitute a vibration damping device.
