PROBLEM TO BE SOLVED: To solve problems of conventional manufacturing methods of a shell type roller bearing: a method for softening one end part after hardening an outer ring, assembling a roller and a retainer therein, and bending the one end part increases the manhour, leaves a softened part in one part of a finished product, and causes deformation in assembling of a housing, a method for plating a bending part in the hardening for preventing the hardening increases the manhour and the environmental loading, and a method for heat-treating after assembling the roller and the retainer in the outer ring can not remove scale inside the outer ring. SOLUTION: The retainer 4 is assembled into the outer ring 2 formed with a first bent part 5 in one end part, a second bent part 6 is formed by bending the other end, and hardening and cleaning are performed with the outer ring 2 and the retainer 4 integrated together. In the cleaning, cleaning material intrudes inside the outer ring 2 from a roller retaining clearance in the retainer 4 so as to remove the scale. Then, the roller is assembled in the outer ring 2 from the inside the retainer through the roller retaining clearance. COPYRIGHT: (C)2004,JPO
