20130074341 | METHOD OF MANUFACTURING CYLINDER APPARATUS - When manufacturing a disk valve having a ring-shaped elastic seal member fixed to one side thereof for use in a cylinder type hydraulic shock absorber, a disk valve blanked from a plate material is set on a bottom of a lower mold member that is curved to be convex on one side.
