PROBLEM TO BE SOLVED: To provide a resin holder for a bearing molded by ejecting molten resin from a resin ejection gate into a cavity, capable of suppressing strength deterioration with a simple structure, and a manufacturing method of the resin holder.SOLUTION: A resin holder for a bearing is molded by ejecting molten resin into a substantially annular cavity 10 from one resin ejection gate 20 provided at an outer peripheral side peripheral edge part 11 or inner peripheral side peripheral edge part 13 of the cavity 10 formed in a molding die 9. In the resin holder for a bearing, a weld W is inclined to a radial direction.SELECTED DRAWING: Figure 1 |
