Abstract
PURPOSE: To produce an inexpensive shaft-sealing part with stable sealing effect by stamping out an annular part with a rough shaped inside rim from elastic materials and holding this annular part by reinforcing rings on the outside rim for shaping bent parts in the inside rim of the annlar part.
CONSTITUTION: An annular part 1 with a rough shaped inside rim is stamped out from elastic materials with almost equal thickness. This annular part 1 is held on its outside rim 4 by reinforcing rings 7 and 9 with almost L-shaped sections. Then, a shaping jig 15, as being rotated, is pushed into the shaft-sealing part 1 by force for forming bent parts 11 on the inside rim of the annular part 1. This process serves to disuse the expensive metal mold processed by screw-grooving that has been needed conventionally for manufacturing the shaft-sealing part with stable sealing effect inexpensively.
