Abstract
With a sealing structure for the sliding unit disclosed here, a sealing member of foam rubber is disposed in a way closing a clearance left open between widthwise opposing covering shells installed on a track rail. A covering shell is composed of a covering side secured to a side wall of a track rail, and seal supporters integral with the covering side. A slider is provided with a projection extending through between inside fronts of the sealing members, which come into abutment against one another. Upon the back-and-forward linear movement of the slider relatively to the track rail, the projection moves in a way deforming the sealing members in expansion/collapse fashion, with keeping the close sliding engagement with the confronting fronts of the sealing members so that the sealing members keep constantly closing the clearance left open between the covering shells.
