Title:
MOTION GUIDE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/203932
Kind Code:
A1
Abstract:
This motion guide device comprises a track member (11), a movement member body part (17), a pair of lid members (30), and a plurality of rolling elements (12). A movement member (13), which is formed of the movement member body part and the pair of lid members, is capable of relative reciprocating motion along the longitudinal direction of the track member. A direction change path (31) formed on the lid members comprises an inner direction change path (31A) and an outer direction change path (31B) that three-dimensionally intersect each other. The lid members are each configured by combining two lid constituent members (51, 61). Among the lid constituent members, when the lid constituent member (61) disposed farther from the installation surface for the movement member body part on the lid member is removed, a part of the portion constituting the outer peripheral side of each of the inner direction change path and the outer direction change path opens to form, for each of the inner direction change path and the outer direction change path, a rolling element insertion opening path (α) into which the plurality of rolling elements can be inserted. With such a configuration, an easy-to-assemble motion guide device can be obtained.
