[Scope of Claim for Utility Model Registration] (1) The upper end of the outer port formed in the valve seat member can be opened at the upper end of the valve seat member constituting the piston body in the piston part or the valve case in the base valve part. In the shock absorber, the shock absorber has a check valve consisting of a leaf valve disposed so as to close the port opening groove from above, and the port opening groove is provided at the upper end of the valve seat member. An annular pressure reducing groove formed concentrically with the port opening groove is provided on the outer periphery of the port opening groove, and the check valve is arranged to close the pressure reducing groove from above together with the port opening groove. Features: Shock absorber. (2) The pressure reducing groove is communicated with the oil chamber above the check valve through a notch formed on the outer circumferential side of the check valve, and is also communicated with the port opening groove through the notch. A shock absorber according to claim 1 of the utility model registration claim. (3) The pressure reducing groove is communicated with the oil chamber above the check valve via a stamped orifice formed in the outer peripheral seat section defining the pressure reducing groove, and
The shock absorber according to claim 1, wherein the shock absorber is communicated with the port opening groove through a stamped orifice formed in the inner circumferential seat section defining the pressure reducing groove.
