PROBLEM TO BE SOLVED: To allow easy installation of rolling elements even in a raceway integrated type and also easily allow easy installation of the rolling elements even when the integrated type raceway is assembled with a retainer in this type of rolling bearing in which spin sliding between the rolling elements and a raceway groove is suppressed and a rolling resistance is reduced to reduce torque. SOLUTION: After the outer and inner rings/retainer are installed at the center of the inner ring raceway groove 3, a small groove 4 for the rotation of the rolling elements is formed in a raceway groove space. The retainer 6 is installed only on one axial pocket face of a pocket 7, and the other face is opened. COPYRIGHT: (C)2004,JPO&NCIPI
