PROBLEM TO BE SOLVED: To provide a welded cage wherein a roller is easily incorporated into a pocket through its outer diameter side, whose width is smaller at the inner diameter side. SOLUTION: The welded cage 40 is non-detachably integrated with an inner ring 20 having the pocket 40c whose width is gradually smaller as tending from the outer diameter side to the inner diameter side and is smaller at the inner diameter side than the diameter of the roller and into which the roller is incorporated through its outer diameter side. On part of the circumferential inside face of the pocket 40c, a region 40f extending from the outer diameter side to the inner diameter side is provided excluding a recessed portion on the peripheral inside face of the pocket, which is pushed and deformed by the roller while being incorporated into the pocket, and a protruded portion 40e is provided which is not deformed.
