One side of cylindrical shell 52 is opened to allow piston rod 54 to pass through, and is formed on the opposite side of this cylindrical shell 52 with the part 60 that is articulated and connected that steel ladle 4 is connected with one of casing 2.
But be arranged on the inner circumferential surface of cylindrical shell 52 to piston rod 54 straight lines and to-and-fro motion, be formed on the end of piston rod 54 with another part 62 that is articulated and connected that is connected of steel ladle 4 and casing 2.
As shown in Figure 5 and Figure 6, friction element 56 comprises: supporting element 70, and it equally spaced is arranged on the inner circumferential surface of this cylindrical shell 52 and operates in the radial direction motion with damping force control unit 58; Friction member 72, it is installed on the external peripheral surface of supporting element 70 and rubs on the inner circumferential surface of this cylindrical shell 52; And resilient member 74, the direction that it is connected between the supporting element 70 and the diameter between supporting element reduces applies elastic force.
