<p>PURPOSE: A shock absorber is provided to reliably bypass a working fluid to a different position through the internal fluid passage of a piston rod without the hindrance of a stopper. CONSTITUTION: A shock absorber comprises a piston rod, an internal fluid passage(12), a stopper(40), and an external fluid passage(O). The internal fluid passage is equipped with an inlet(121) on the outer circumference of a piston rod. The internal fluid passage bypasses a working fluid through the inside of the piston rod. The stopper is installed on the outer circumference of the piston rod and covers the surrounding of the inlet. The external fluid passage is formed in between the stopper and piston rod and is connected to the inlet from the upper side of the stopper.</p> |
