METHOD OF MANUFACTURING ROLLING ELEMENT CONNECTING BODY

摘要

PURPOSE: To provide a method of manufacturing a rolling element connecting body capable of manufacturing a smaller rolling element connecting body easily and at low cost and manufacturing the rolling element connecting body excellent in tensile strength and bending strength even when it is miniaturized. CONSTITUTION: This method of manufacturing a rolling element connecting body to align a large number of balls 3 in one row with specified intervals and to hold them free to rotate comprises a first process to mold a flat band type belt member 21 of a synthetic resin, a second process to drill holding holes through which the balls 3 are fitted with plays in one row on the belt member 21 and a third process to arrange the balls 3 in the holding holes, to injection-mold a spacer part 22 to hold the ball 3 between the adjacent holding holes while using the ball 3 by coring it and to confine the ball 3 in the holding hole.
