<P>PROBLEM TO BE SOLVED: To prevent a main shaft of a shaft from receiving extreme pressure and reduce wear of the main shaft for high reliability. <P>SOLUTION: The main shaft of the shaft includes a first undercut 140 formed at a position opposed to a bearing extension upper end 139 of a bearing extension 138 of a cylinder block 114. The first undercut 140 is not symmetric relative to a vertical direction of the center of the main shaft of the shaft, thereby preventing the main shaft 111 of the shaft 110 from receiving extreme pressure and reducing wear of the main shaft 111 of the shaft 110, thus achieving a highly reliable hermetic compressor. <P>COPYRIGHT: (C)2013,JPO&INPIT |
