摘要： PROBLEM TO BE SOLVED: To provide a technique for molding holders each having a small width size integrally and inexpensively by a simple holder molding method.
SOLUTION: At least two pockets 6a and 6b holding each of at least two rolling elements 4 rotatably are molded in two or more rows along the circumferential direction R. When each pocket 6a constituting one row and each pocket 6b constituting the other row mold the holders 2 arranged in the direction P crossing the circumferential direction at right angles, a molding (holder) is left in one split mold, and projection force is applied to the left molding to demold the molding from one split mold. In this case, between the parts of each pocket 6a constituting one row, receiving parts 8 for receiving the projection force are molded integrally. In this way, by improving the rigidity between the parts of each pocket, the molding is left in one split mold when a split mold is split.
