MOTION GUIDE DEVICE AND SCREW DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/137529
Kind Code:
A1
Abstract:
A motion guide device and a screw device which each comprise a cover for protecting the device against moisture, such as coolant, and powder dust.
A motion guide device provided with a raceway member (11), a moving-element body (21) mounted to the raceway member (11) through rolling bodies (32), and lid members (22) each provided to each end surface of the moving-element body (21) in the direction of relative movement thereof. Covers (50) are mounted to the motion guide device, and each cover (50) consists of a cover body (51) for covering a lid member (22) and of a seal section (55) provided between the cover body (51) and a lid member-side end surface of the moving-element body (21) and sealing the gap between the lid member-side end surface and the cover body (51). The configuration reliably prevents moisture, such as coolant, and foreign matter, such as dust and swarf, from entering the inside of a moving element (20).
