In a roller retainer assembly, a roller retainer 15 is thinned to retain individual one of plural rollers 7 circulating in a roller circulation path inclusive of linear and curved races and to hold opposite side surfaces of the roller 7 and front and rear surfaces thereof in the roller moving direction. A combination of linear and curve guide portions 16a and 16b different in inclination angle and a combination of linear and curve guide portion 17a and 17b different in inclination angle are formed respectively in opposite end surfaces of the roller retainer 15 in a retainer moving direction. In a linear race, the linear guide portions 16a and 17a come into contact with adjacent roller retainers 15 respectively. In a curved race, the curve guide portions 16b and 17b come into contact with adjacent roller retainers 15 respectively.
