| 发明名称 | Cage, rolling bearing, method for manufacturing cage, and injection mold | ||
| 摘要 | A cage (14) is made of a magnesium alloy and has a light weight and a high strength. The cage (14) is made of a magnesium alloy such as AZ91D, and is formed by means of injection molding. In this cage (14), a confluence region is brought away to outside the cage (14) during the injection molding. The confluence region is a region including voids formed by merging of flows of the magnesium alloy. | ||
