<p><P>PROBLEM TO BE SOLVED: To provide a holder free from a void and having high strength and excellent dimensional accuracy, low in cost without requiring an another mechanism for the exclusive use of compression and the deburring work of a pocket. <P>SOLUTION: A molding mold is used while being provided with: a cavity agreeing with the shape of the holder; a resin pool provided outside a holder circular part equivalent position continuously in a proper place of the holder circular part equivalent position of the cavity; a void continuing to the resin pool; and a movable pin sliding in the void. In a state that the movable pin is pulled to form a space between the tip of the movable pin and the resin pool, a molten resin composition is injected to fill the cavity, the resin pool and the space, and then, before the solidification of the molten resin composition, the movable pin is moved to the resin pool side to push the molten resin composition in the resin pool into the cavity, and the molten resin composition is solidified in a compressed state to manufacture the holder. The rolling bearing is provided with the holder obtained in this way. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
