Filed: 2002-03-27
Abstract: <P>PROBLEM TO BE SOLVED: To improve endurance of a shock absorber by reducing wear of a piston rod, a rod guide, and an oil seal for the shock absorber in which magnetic fluid is filled in.  <P>SOLUTION: The shock absorber 10 comprises a cylinder 11, an oil seal 12, a rod guide 13, and a piston rod 15. MR fluid 14 is filled in inside the cylinder 11. A magnetic particle adsorption device 20 formed by a permanent magnet 21 and a diaphragm 22 is assembled on a side portion of a fluid chamber of the rod guide 13. In this structure, the diaphragm 22 is bent to a permanent magnet side when a fluid chamber at a rod side becomes high pressure, and the MR fluid 14 approaches to the permanent magnet 21. Thus, ferromagnetic particles in the MR fluid 14 are adsorbed by the permanent magnet 21 via the diaphragm 22, and consequently, wear of the piston rod 15, a guide bush 13b, and a seal portion 12a are reduced.  <P>COPYRIGHT: (C)2004,JPO
