ピストンロツドロツク機構。 A shock absorber that buffers a load acting on a piston rod within a cylinder body and returns the piston rod by a piston return spring within the cylinder body, and a cylindrical ball holder that allows the piston rod to pass through the head side of the cylinder body. and a ball capable of engaging with a locking groove provided on the outer periphery of the piston rod or a member integral therewith is removably mounted on the ball holder,
A slider is mounted so as to be slidable in the axial direction, and the slider is urged by a slider return spring weaker than the piston return spring to a position where a portion of the slider protrudes outward from the ball holder,
A piston rod locking mechanism for a shock absorber characterized in that the slider is provided with a ball pushing portion that pushes the ball to engage the lock groove when the slider is retreated against the slider return spring. .
