<p><P>PROBLEM TO BE SOLVED: To provide a thrust roller bearing for a swash plate type compressor, which prevents local wear of an outer diameter side circumference surface in an axial direction out of the outer circumference surfaces of a roller. <P>SOLUTION: This thrust roller bearing 12 for the swash plate type compressor 1 is assembled between cylinders 2, 3 and a swash plate 8 reciprocating a piston 6 by rotation action of a rotary shaft 7. The bearing is provided with: a first raceway 70 locally butting on a seat 17 of the swash plate 8 either of an inner diameter side or an outer diameter side of an outer surface thereof; a second raceway 60 locally butting on a seat 14 of the cylinder 2 either of an inner diameter side or an outer diameter side of an outer surface thereof and having same inner and outer diameter dimensions as the first raceway 70; and a plurality of rollers put between both of the raceways 60, 70. A center position C in an axial direction of the roller 10 is set on an outer diameter side of a center position RC between an outer diameter position RO and an inner diameter position RI of both of the raceways 60, 70. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
