摘要： A method of molding a movable block for a rolling motion guide device can effectively prevent the formation of burrs in the rolling member rolling groove and accurately positioning the movable block body in a molding die.The positioning of the movable block body in width, vertical and longitudinal directions is performed at plain surfaces that are different from the rolling member rolling groove, so that damage or injury of the rolling member rolling groove can be prevented. Further, the molding material is shut off at either both end portions or both side peripheries of the rolling member rolling grooves, so that the molding material can be prevented from invading into the rolling member rolling grooves.
