PURPOSE:To ensure a simple structure, easy working and assembly as well as excellent damping characteristic and high reliability. CONSTITUTION:In a shock absorber of a body of revolution provided with a pivot shaft 13 connected to a lower portion of the body of revolution, a spherical bearing 12 for supporting said shaft 13, a movable disc 9, which can integrally be moved in the radial direction with the bearing 12, a ringed rest plate 15 for generating damping, which is placed facing to the disc 9, which can freely be slid in the axial direction and which operation in the radial direction is regulated, an oil tank 1 for encasing these parts, etc., the materials of said disc 9 and the ringed rest plate 15 are made to be aluminum or aluminum alloy, and an alumite treating layer or layers 20, 21 produced by impregnating 4-fluoethylene resin to the alumite treating layer are shaped to either of one surface or both surfaces of both 9, 15. 5 is a steel ball, 7, 8 are magnets, 14 is a sphere and 17-19 are clearances. |
