<p><P>PROBLEM TO BE SOLVED: To provide a thrust needle bearing capable of reducing the wear resulting from slip of its cylindrical rollers while the cost remains low and provide a compressor for a car air conditioner using such needle bearings. <P>SOLUTION: The thrust needle bearing 16B is structured so that a plurality of rollers 16e1 and 16e2 are accommodated in one pocket, and its rolling resistance is decreased by lessening the part ranging out of the PCD of the rollers, and also the cost can be suppressed by forming its retainer 16h from one piece of plate material being folded. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
