An upper disc flange (47) is arranged at the upper end of the cylinder (35) with a disc flange at the upper end, and a concave groove (80) is arranged on the upper portion of the stepped cylinder (11). By the aid of magnetic force, blades in the damper are driven to rotate and the pistons in the dumper are driven to axially move. When the blades rotate and the pistons move axially, the damping fluid is led to flow through small round through holes on the blades and the pistons to consume energy, so that the rotation around the axes of the pistons and the vibrations along the axes of the pistons can be controlled. Without sealing member, the damping fluid is not easy to leak from the damper.
