PROBLEM TO BE SOLVED: To make a slider ready for weight reduction and space reduction. SOLUTION: A bottom surface 50 of an installation hole 5 of a slider body 2A is flatly formed. Thus, a minimum value of a dimension T of the slider capable of preventing a through-hole 23 for a return passage 22 from overlapping with the bottom surface 50 of the installation hole 5, can be reduced more than a conventional value, while securing the required depth of a female screw 51.
