Abstract

PURPOSE:To enable arbitrary adjustment of the damping characteristic of the movable part of the liquid damping part by using the movable part of a liquid damping device as a magnetic damping part disposed in opposite to the above movable part and consisting of a magnetic material and an electromagnetic coil, one of which is connected to the above movable part. CONSTITUTION:When a load indicated by arrow F is applied to a mounting plate 17 connected to a piston rod 8, the piston rod 8 is displaced in accordance with the damping characteristic of a liquid damping device 12. Upon this displacement, when a current is supplied to an electromagnetic coil 15, a damping force acts on the mounting plate 17 by a magnetic damper 18. In addition, upon this occasion, a magnetic fluid 20 is projected from a groove 19 to cause the fluid 20 to be attracted to the internal and external peripheral surfaces whereby it is possible to obtain a generated damping force. Consequently, the damping force of the liquid damping force of the liquid damping part 12 acts constantly on the mounting plate 17 so that the damping force due to the magnetic damping part 18 and the magnetic fluid 19 can be arbitrarily applied to the mounting plate 17.
