<p>PROBLEM TO BE SOLVED: To prevent cooling water, abrasion powder occurring in traveling, or the like from being accumulated to a recess part of a side surface in the upper side of a guide rail, even in a case where the guide rail is fixed to a vertical surface with a linear motion direction facing to a horizontal direction, in a roller guide having the bottom surface of the recess part with both rolling surfaces as a wall surface between the rolling surfaces of the side surface of the guide rail.SOLUTION: A roller guide has a bottom surface 13a of a recess part 13 with both rolling surfaces 11, 12 as a wall surface, between the rolling surfaces 11, 12 of the side surface of a guide rail 1. The guide rail 1 has a through hole 15 penetrating across the bottom surface 13a of both side surfaces in a width direction.</p> |
