Title:
LINEAR MOTION GUIDE DEVICE AND METHOD FOR ASSEMBLING SAME
Document Type and Number:
WIPO Patent Application WO/2019/112021
Kind Code:
A1
Abstract:
A slider (2) of a linear motion guide device comprises: a slider main body (2A); a slider end surface component attached to the movement-direction end part of the slider main body (2A); and an underseal (30) that seals a gap between a guide rail (1) and the slider (2). The underseal (30) has a seal member (31) comprising a main lip (31g) that contacts the guide rail (1). The seal member (31) has a main-body-side lip part (31e) that projects toward a lower surface (6c) of the slider main body (2A) and extends along the movement direction of the slider (2). The main-body-side lip part (31e) contacts both the lower surface (6c) of the slider main body (2A) and a lower surface of the slider end surface component. This makes it possible to maintain high dust prevention and waterproofing properties between the underseal and the lower surfaces of the slider main body and the slider end surface component.
