Document Type and Number:
WIPO Patent Application WO/2013/168359
Kind Code:
A1
Abstract:
This motion guide device is provided with: a raceway member on which rolling body rolling sections are formed; a movement member on which loaded rolling body rolling sections facing the rolling body rolling sections are formed and which have rolling body return passages extending substantially parallel to the loaded rolling body rolling sections; a pair of lid members (6, 6) in which direction change paths (16) for connecting the loaded rolling body rolling sections and the rolling body return passages are formed; and rolling bodies arranged in a rollable manner within rolling body circulation routes configured from the loaded rolling body rolling sections, rolling body return passages, and direction change paths (16). The movement member and the lid members are provided with affixation means. An arbitrary one of the affixation means is provided in each of the vicinities (A) of scooping sections (16a) at which the direction change paths (16) formed in the lid members (6) scoop rolling bodies rolling from the loaded rolling body rolling sections. Other arbitrary affixation means (21, 22) are provided at positions close to the side opposite the side on which the raceway rail is installed. As a result of this configuration, parts of the motion guide device have high strength, and the motion guide device is highly durable and highly reliable.
