<P>PROBLEM TO BE SOLVED: To solve several problems: wherein, in a conventional shock absorber, since damping force is changed by a moving speed regardless of the position of a piston, ride quality and maneuverability particular in an operation stroke intermediate region are degraded when the damping force is increased; and, when the damping force is decreased on the contrary, the shock absorber is easily fully extended at the maximum extension, bottom contact easily occurs at the maximum flexure, and ride quality, maneuverability and the like are degraded. <P>SOLUTION: Holes are provided on a cylinder in contact with a piston. The number of holes is multiple, or each hole is a long one. Thereby, a position dependent shock absorber is provided by the hole(s) divided by the piston. By changing the size of each hole, and changing the positions of the holes from equal intervals, optional damping can be generated. The hole communicates with multiple cylinders or communicates with an outer cylinder. <P>COPYRIGHT: (C)2012,JPO&INPIT |
