A slider mounted movably on a guide rail interposing many balls therebetween is constructed by assembling as a unit, a race member having ball rolling grooves at both sides, a circulator having ball circulating grooves opening upwardly, and a cap sandwiched between the race member and the circulator. The cap is formed with column members protruding from the upper surface upwardly and aligned axially, and each of the column members has a threaded hole for attaching a member to be driven to the slider. The race member has through holes for the column members, so that the column members having the screw holes are exposed.
