Abstract:
1. A damping force generator for a hydraulic shock absorber comprising: a piston providing a partition between two oil chambers; a valve seat secured to the piston; a damping valve disposed on one side of the valve seat; and a check valve stacked on the damping valve such that a high pressure in one of the oil chambers pushes open the damping valve to generate a damping force and a high pressure in the other of the oil chambers pushes open the check valve, wherein the valve seat has secured portions and recessed portions adjacent to each other along a circumference thereof, the secured portions, together with parts of a circumference of the damping valve seated thereon, being secured to the piston and the recessed portions being spaced apart from the other parts of the circumference of the damping valve, and the damping valve undergoes deflections with the boundary between the secured portion and the recessed portion of the valve seat as a supporting point, and inner and outer peripheries of the damping valve are disposed on an outside of line segments each connecting two circumferentially adjacent supporting points of the valve seat.
