To increase load capacity of a thrust bearing which is interposed between members eccentrically rotating mutually to support thrust load.
In a group of two rollers 14, 24 that are arranged for linear motion and have cages 16, 26, rolling axial centers of the rollers 14, 24 are perpendicular to each other, the rollers 14, 24 are respectively disposed on each side of an intermediate ring 30, and two bearing washers 12, 22 sandwich the rollers 14, 24 from the sides thereof, so that the eccentric rotating motion of the bearing washers 12, 22 is allowed. For scroll compressor or the like, for example, the first bearing washer 12 is fixed to a revolving scroll member 10, and the second bearing washer 22 is fixed to a housing 20. Each of cages 16, 26 is constituted of an inner lid and an outer lid formed in a shape of U in section by press-molding with a steel plate, and the inner lid and outer lid are overlapped with each other in a telescopic manner to form a box-shaped section.
