In a damping force generator for a hydraulic damper, the valve is protected from pressure rise in the damper and its durability is thereby enhanced. The damping force characteristics can be vary in stepwise fashion by providing a main leaf valve 21 and a sub-leaf valve which closes an opening 21A formed in the main leaf valve 21, and the approximate mid-point of the main leaf valve 21 is supported by a plurality of intermediate seat surfaces 16 from the side of a port 13. The outer circumference of a main leaf valve 64 is supported by an outer circumferential seat surface 62, and the outer circumference of a sub-leaf valve 65 extends outwards to the vicinity of a part where the outer circumference of the main leaf valve 64 and the outer circumferential seat surface 62 overlap.
A damping force generator for a hydraulic damper comprising a main leaf valve and a sub-leaf valve laminated on each other, wherein said sub-leaf valve closes an opening formed in said main leaf valve and has a lower bending rigidity than that of said main leaf valve, only said sub-leaf valve opens to generate a damping force when an extension/compression speed of a piston rod is low, and said main leaf valve opens to suppress increase of damping force when the extension/compression speed of said piston rod is high, and said generator is characterized in that:
