PROBLEM TO BE SOLVED: To provide a flat bearing having reduced cost by reducing the number of machining processes for a cage. SOLUTION: The flat bearing 5 comprises a pair of raceway plates 50a, 50b laminated with each other, a number of rolling bodies 51 mounted between the raceway plates 50a, 50b, and the plate cage 52 having a number of pockets 55 for storing the rolling bodies 51. An outside guide means 54a and a turning guide pin 54b are provided on the turning outer periphery side and the turning inner periphery side, respectively, of the cage 52 for giving relative thrusting turn to the raceway plates 50a, 50b with a turn axis parallel to the laminating direction of the raceway plates, as a center. The cage 52 is formed by press molding. COPYRIGHT: (C)2005,JPO&NCIPI
