A damping force generator for hydraulic shock absorbers. The valve is protected against an increase of pressure in the hydraulic shock absorber, and the durability of the generator is thereby improved. A gradually varying damping force characteristic is obtained by a main leaf valve (21) and a sub-leaf valve adapted to close an opening (21A) formed in the main leaf valve. A substantially central portion of the main leaf valve (21) is supported from the side of a port (13) by a plurality of intermediate seat surfaces (16). The outer circumferential edge of the main leaf valve (64) is supported by the seat surface (62) on the circumferential side, and that of the sub-leaf valve (65) is extened close to the position in which the outer circumferential edge of the main leaf valve (64) and the seat surface (62) are superposed on each other. <IMAGE>
