<P>PROBLEM TO BE SOLVED: To provide a refrigerant compressor using a bearing having improved wear resistance while shortening a time for machining the bearing and reducing material loss. <P>SOLUTION: The bearings 2c, 4a each use a carbon graphite base material which is obtained by baking such a molded product that kneaded material containing inorganic filler is molded into an approximate usable shape. The carbon graphite base material has an area porosity of 15% or less when found under a microscope, contains ash, and is filled with α solid solution of phosphor copper or copper containing phosphor. <P>COPYRIGHT: (C)2008,JPO&INPIT |
