PROBLEM TO BE SOLVED: To provide a mold for manufacture of a belt for housing the rolling elements of the linear motion guide which can prevent or suppress the occurrence of under fill on molding. SOLUTION: The mold 90 has a molding shape section 93 having the shape for the molding, between an upper mold 91 and an under mold 92. The molding shape section 93 has spacer sections which interpose the molded belt 50 for housing the rolling body between adjacent balls in an endless circulating passage and connection arm sections connecting the spacer sections mutually and is constructed so as to align the balls in the direction of the endless circulating passage. The upper mold 91 has a divided structure having a division position BL at a position passing the position 91t in the spacer sections 51 where the end part of the outer periphery in the inner/outer periphery direction in the endless circulating passage is molded.
