求の範囲第１項記載のシヨツクアブソーバ。[Claims for Utility Model Registration] (1) Disposed in a bypass passage that enables communication between the upper chamber and the lower chamber by bypassing the piston portion that divides the inside of the cylinder into an upper chamber and a lower chamber; A rotary valve, which opens and closes the bypass passage by rotation and allows adjustment of the damping force generated when the piston portion slides, is bored in the piston rod to form the bypass passage. A connection that is arranged so that an appropriate gap is formed between the outer periphery of the rotary valve and the inner periphery of the vertical hole when the rotary valve is housed in the vertical hole, and that allows connection of the control rod. 1. A shock absorber characterized in that a port is provided in a thick wall portion on a side thereof, the port penetrating through the thick wall portion to enable communication between the outside of the connecting portion and the inside of the rotary valve. (2) The area of the port drilled in the thick wall of the connecting part of the rotary valve is larger than the area of the gap formed between the outer periphery of the rotary valve and the inner periphery of the vertical hole in the piston rod. A shock absorber according to claim 1 of the utility model registration claim.
