PROBLEM TO BE SOLVED: To provide a fluid sealed vibration control device of simple structure capable of exhibiting widely different spring characteristics of a main rubber elastic body in two directions different from each other at a right angle against a shaft and capable of securing durability of the main rubber elastic body. SOLUTION: A solid rubber wall 16 is formed with an inner surface recessed part 70 and an outer surface recessed part 72 on both side of an inner shaft member 12 in one direction at a right angle against the shaft to form a pair of thin parts 74 and a pair of thick parts 76 positioned opposite to each other in directions crossing each other at a right angle against the shaft in the solid rubber wall 16. The inner surface recessed part 70 is formed to be recessed in the axial direction, and the deepest part is positioned on an inner shaft member 12 side, and the outer surface recessed part 72 is formed so that the deepest part thereof is formed on an outer cylinder member 14 side. The deepest part of the inner surface recessed part 70 is positioned on a small diameter side in the axial direction of the solid rubber wall 16 than the deepest part of the outer surface recessed part 72, and the inner surface recessed part 70 and the outer surface recessed part 72 are overlapped with each other in the direction at a right angle against the shaft in the solid rubber wall 16.
