PROBLEM TO BE SOLVED: To provide a retainer for a bearing, which retainer hardly breaks because the strength of welded portions is large, and further is inexpensive. SOLUTION: The retainer 1 for the bearing is configured so as to be manufactured by the injection molding using a forming material composed of polyamide 66, which is a polymer having a high melting point, and 10-20 wt.% polyamide 6 blended with the polyamide 66, which polyamide 6 is a polymer having a low melting point.
