直線摺動用ベアリングユニツトの軌道レール。[Claims for Utility Model Registration] A bearing body is fitted to a rail body which is attached to a fixed bed with bolts at intervals in the longitudinal direction so as to be movable in a straight line, and between opposing surfaces of the bearing body and the rail body. In a linear sliding bearing unit in which a rolling element is interposed in the rail body, a concave groove is formed in the entire length of the rail body in the longitudinal direction passing over the bolt, and both ends of the concave groove in the width direction are formed in an inverted tapered shape. 1. A track rail for a linear sliding bearing unit, characterized in that a cover integrally formed of an elastic body having a trapezoidal cross section is fitted into the concave groove, the width being shortened by the elasticity of the cover.
