Title:
LINEAR GUIDE DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/068860
Kind Code:
A1
Abstract:
A linear guide device has a guide rail (12), a slider body (15), an end cap (16), a large number of rolling bodies (18), and separators (22). The slider body (15) has a slider side rolling body raceway surface opposed to a rail side rolling body raceway surface (13) formed on the guide rail (12). The end cap (16) has a rolling body direction switching path (21) communicating with a rolling body load rolling path (19) formed between both rolling body raceway surfaces of the guide rail (12) and the slider body (15) and also communicating with a rolling body return path (20) formed in a penetrating manner in the slider body (15), along the longitudinal direction of the guide rail (12). In conjunction with relative linear movement of a slider (14) constituted of the slider body (15) and the end cap (16), the rolling bodies (18) roll in the rolling body load rolling path (19), the rolling body return path (20), and a rolling body direction switching path (21). The separators (22) are arranged between every two adjacent rolling bodies (18). The end cap (16) has a through hole (25) for assembling the rolling bodies (18) and the separators (22) from the outside of the slider (14) into the rolling body return path (19) and also has a cap member (26) removably fitted in the through hole (25). The cap member (26) forms part of the rolling body direction switching path (21).
