Motion guide device

摘要

Provided is a motion guide device in which a moving member is equipped with circulation path moldings. With the device, ease of assembly and moldability can be improved. A moving member is provided with circulation path moldings, which have: holding sections that extend along loaded rolling-element rolling sections; return path configuring sections that configure return paths; and a pair of direction-change path inner circumference configuring sections that configure the inner circumferences of a pair of direction-change paths. The circulation path moldings are provided with a first molding in which one direction-change path inner circumference configuring sections is integrally molded with the holding section and a second molding in which the other direction-change path inner circumference configuring section is integrally molded with the return path configuring section. The first molding and the second molding are separate bodies.

主权项

1. A motion guide device comprising:
a track member having a rolling-element rolling section; and a moving member movably assembled to the track member via a plurality of rolling elements and having a circulation path that includes a loaded rolling-element rolling section opposed to the rolling-element rolling section of the track member, a return path parallel to the loaded rolling-element rolling section, and a pair of direction-change paths connected to the return path and a loaded rolling-element rolling path provided between the rolling-element rolling section and the loaded rolling-element rolling section, the moving member being provided with a circulation path molding having a holding section that extends along the loaded rolling-element rolling section, a return path configuring section that defines the return path, and a pair of direction-change path inner circumference configuring sections that define inner circumferential portions of the pair of direction-change paths,wherein:
the circulation path molding includes a first molding in which one direction-change path inner circumference configuring section is integrally molded with the holding section, and a second molding in which the other direction-change path inner circumference configuring section is integrally molded with the return path configuring section; and the first molding and the second molding are separate bodies.
