Claims (1)

[Scope of Claim for Utility Model Registration] (1) As reciprocating parts such as a table, which is a component of a machine tool, slide on a work bed, cover bodies of different sizes are telescopically telescopic. In the telescopic cover structure formed to cover the work bed, the bottom surface of the shoe attached to the lower part of the cover body and slidably supporting the cover body with respect to the work bed is adapted to prevent expansion and contraction movements. With respect to the traveling direction, the length always spans two adjacent convex portions of the concave and convex portions that constitute the surface roughness of the sliding surface of the work bed.
A telescopic cover structure characterized in that the tip portion is configured in a protruding shape. (2) Utility model registration claim 1, characterized in that the protrusion is formed of a rectangular corner by attaching a shoe whose bottom surface is rectangular obliquely to the advancing direction of the telescopic movement. Telescopic cover structure as described in section.
