Abstract: A hydraulic shock absorber includes a valve body having a second valve which is fixed to the valve body on a central axis CL side of the second valve and covers an open end of a second oil passage in the valve body. The second valve is deformable in a direction away from the valve body when the valve is applied with force from the valve body side. The second valve is configured: (a) to include a first through-hole formed in a circumferential direction thereof, (b) have lower stiffness, with respect to force from the valve body side, on a second through-hole side than on a third through-hole side and (c) such that a first corner portion C1 of the first through-hole has higher stiffness than a second corner portion C2 of the first through-hole positioned on the third through-hole side.

Abstract translation: 液压减震器包括具有第二阀的阀体，该第二阀在第二阀的中心轴线CL侧固定到阀体上并且覆盖阀体中的第二油通道的开口端。 当阀被施加来自阀体侧的力时，第二阀可沿远离阀体的方向变形。 第二阀被构造成：（a）包括沿其圆周方向形成的第一通孔，（b）相对于来自阀体侧的力在第二通孔侧具有比在 第三通孔侧和第三通孔侧的第一通孔的第二角部C2比第一通孔的第一角部C1高。
