Abstract
In sealing means for a slider unit in which sealing members of foam rubber are arranged to close sidewise clearances left open between a dustproof cover and side walls of a track rail, the improved sealing means is directed to making sure of effective sealing performance, prolonging a durable service life of the sealing member, and also making mounting of the sealing member to the clearances easier. Sealing members of flexible foam rubber rich in restoring force are arranged in the clearance between the dustproof cover and the side walls of the track rail. The sealing members, while fastened to the dustproof cover, are allowed to experience any deformation of expansion/collapse when sideward wings of the slider moves back and forward between the confronting sealing members and the side walls, with keeping close sliding engagement with the associated surfaces of the wings. Especially, the sealing member made in a configuration of substantially quadrilateral in traverse cross-section is preferable to help ensure high sealing performance because such sealing member is expansible and collapsible with keeping substantially the initial quadrilateral.
