<p><P>PROBLEM TO BE SOLVED: To provide a method for modifying a plastic molded product with which an affinity for a lubricant is imparted to the plastic molded product and to provide the plastic molded product suitably usable even under severe service conditions. <P>SOLUTION: The method for modifying the plastic molded product is carried out as follows. A crown-shaped holder 14 composed of glass-fiber reinforced polyamide 66 is dipped in supercritical carbon dioxide containing a lubricating oil to thereby carry out a modification treatment for permeating the lubricating oil into the surface of the crown-shaped holder 14. The resultant crown-shaped holder 14 subjected to the modification treatment is assembled in a deep groove ball bearing. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
