The invention which is the center of the first body opening to the inner surface of the storage container is formed the storage space which is open upward in one disk is being dugoseo the interval to be vertically fixed in a horizontal multiple; Viscous fluid that is filled in the storage space to lock the said first disc; Located the bottom plate on the floor of the storage space, located a hollow shaft which is vertically fixedly from the lower plate so as to penetrate the center of the first disc, the second disc is fixed to the number presented dugoseo a gap up and down horizontally in the hollow shaft a second body which are overlapping in the horizontal direction to be spaced apart in the first disc, so as to be movable in the horizontal direction, installed in the inside of the first body; And a support shaft in the hollow shaft is inserted to be vertical, the upper plate body 3 to become the object of the vibration damping is fixed to the installation in which the support shaft fixed to the top; relates to a damper using a viscous fluid to include.
According to the invention, it is possible to increase the efficiency of the vibration damping, and control of the vibration damping force to control for easy, it is possible to increase the vertical and horizontal stroke.
