Abstract
A buried plug has interference which is made to exert a load or stress less in a widthwise direction of the guide rail than in a lengthwise direction of the guide rail, thereby protect raceways on the guide rail against any deformation such as bulge. The buried plug has a mating zone to press fit into a counterbore of a bolt hole and a leading zone to guide the mating zone into the counterbore. Let assuming a definition that a direction perpendicular to a lengthwise direction of the guide rail is referred to a direction opposed to the raceway surface or the widthwise direction of the guide rail, the interference exerting a force on the counterbore in the widthwise direction is determined less than the interference exerting the force on the counterbore in the lengthwise direction of the guide rail.
