PROBLEM TO BE SOLVED: To facilitate incorporating work of rolling elements and to reduce the manufacturing cost of a slider main body by eliminating drilling of a tap hole or a through-hole of a rolling element passage in an end face of the slider main body. SOLUTION: One of a plurality of long members 30 slightly shorter than an axial length of the slider main body 20A is arranged in a substantially center part of a groove part 21 formed on an upper face of the slider main body 20A. Two rows of rolling element passages 80 corresponding to a space between two rows of rolling elements rolling grooves 3 and 31 on both side parts of a guide rail 1 are formed on the groove part 21. The remaining long members 30 are arranged along an outer face of the slider main body 20A. Rolling element circulating components 50 on both end parts of the slider main body 20A are fixed on both end parts of all long members 30 by screws. The groove part 21 is covered by a cover 70.
