<P>PROBLEM TO BE SOLVED: To improve a fluid pressure shock absorber such as an inverted type front fork housing an upright type damper and functioning as an air suspension, and a rear cushion unit. <P>SOLUTION: In the fluid pressure shock absorber including a shock absorber body comprising an outer tube 1 on a vehicle body side and an inner tube 2 on an axle side to be slidably inserted in the outer tube 1, the upright type damper 3 having a cylinder 4 housed within the shock absorber body and erected at an axial center part of the inner tube 2, and a rod 4 fixed to the outer tube 1 and inserted movably in the axial direction in the cylinder 4, and an air chamber G formed between the shock absorber body and the damper 3 to function as an air spring, a balance spring S is provided which does not cause spring reaction within a constant stroke range from the most retracted time of the fluid pressure shock absorber, and is elongated if the fluid pressure shock absorber is extended to a certain length or more to cause predetermined spring reaction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
