Claims

[Scope of utility model registration request]

(1) At least a pair of guide rails provided with guide grooves over the entire length and arranged parallel to each other, and a plurality of rolling elements rotatably engaged with the guide grooves, and A slider mechanism comprising a retainer that slidably engages with a guide rail, and a slider that has an engagement groove that engages with the rolling element and is movably supported on the guide rail via the rolling element. A slider mechanism characterized in that at least one end of the guide groove and the retaining groove is chamfered to facilitate introduction of the rolling element into the groove.

(2) The guide groove and the engagement groove have a substantially ■-shaped cross section, and the rolling elements are substantially cylindrical cross rollers in which approximately half of the rolling elements have rotational axes that are substantially perpendicular to each other. A slider mechanism according to claim 1 of the patented utility model.

(3) The slider mechanism according to claim 2, wherein the engaging portion of the cross roller with the guide groove and the engaging groove is chamfered.
