PROBLEM TO BE SOLVED: To provide a vibration resisting unit having easily changeable spring stiffness. SOLUTION: An air sealing member is provided between a capacity cylinder and a movable piston body therein, and a vibration resisting pressure chamber is formed with the air sealing member, a top plate on which a vibration resisted object is placed, the capacity cylinder and a bellows. The capacity of the vibration resisting pressure chamber can be changed with the movement of the movable piston body, and so the spring stiffness of the vibration resisting unit can be easily adjusted.
