[0002]

2. Description of the Related Art Conventionally, a linear guide for guiding the linear sliding motion of various machines has been made up of a track rail as a guide rail and a slide unit sliding on the track rail. The slide unit is mounted slidably and without rattling so as to straddle the track rail and sandwich the side surface of the track rail from both sides. Further, the mounting surface, which is the outer surface of the slide unit, is formed parallel to the rail top surface of the track rail.

[0003]

In the case of the above-mentioned prior art, the mounting surface of the slide unit is only a surface parallel to the upper surface of the track rail, and is, for example, a vertical direction with respect to the mounting surface provided horizontally. When attempting to mount a member having a surface to be mounted, the mounting posture of the track rail itself has to be changed, which poses a problem that the mounting direction of the member mounted on the slide unit is limited.
Furthermore, since the track rail is used by being fixed to the frame material, the sliding operation is performed with the slide unit exposed from the frame material, so that in the sliding range,
It was likely to cause interference with other members.

The present invention has been made in view of the above-mentioned problems of the prior art. It is possible to select the mounting posture of an external member to be mounted with a simple structure and to prevent interference with other members. An object of the present invention is to provide a linear sliding device that is unlikely to occur and has high safety in sliding operation.
