Claims (1)

[Scope of utility model registration request] a shock absorber comprising a piston rod having a vertical hole extending in the axial direction and two sets of horizontal holes opened in the radial direction from two locations spaced apart in the axial direction of the vertical hole;
A main air chamber communicating with one of the sets of horizontal holes, an auxiliary air chamber communicating with the other of the two sets of horizontal holes, and a bound stopper disposed surrounding the piston ron 2 in the main air chamber. The suspension includes a bound stopper capable of blocking the horizontal hole opening into the main air chamber when the shock absorber is compressed beyond a predetermined value.
