Abstract
An overrun preventing device to prevent a slider from falling off of a guide rail is fixed to one end of the guide rail of a linear guide apparatus. The overrun preventing device includes a main body made of a metal plate having an inverted U-shaped cross section, and a slide plate. The main body has lift preventing plate portions formed by bending lower edges of both side walls of the main body inwardly at right angles so that the lift preventing plate portions are engaged with rolling member rolling grooves formed in both sides of the guide rail to prevent upward movement of the main body. The slide plate has a rectangular shape. One end of the slide plate is inserted between the main body and the upper surface of the guide rail so that the slide plate is expandable with respect to the main body depending on a fixing position of the slide plate on the guide rail. In order to adjust the fixing position, a pair of axial, parallel slots are formed in an upper plate portion of the main body and positioning screws are screwed into the end of the slide plate after passing through the slots. An impulse absorbing member made of rubber is attached to the other end of the slide plate to ab…
