Abstract

PURPOSE:To make it possible to obtain high executability since a travelling member can be easily mounted independent of the execution of a rail, by a method wherein cut parts for mounting the travelling member are formed on the sidewall of a rail element member, and a cover plate with which the cut parts are covered and the travelling member is prevented from deviating, is removably provided. CONSTITUTION:A plurality of rail element members 4a are connected in longitudinal direction. A rail 4 with a U-shaped or inverse U-shaped section is thereby formed and a movable member is movably and rotatably mounted thereon through a travelling member. Cut parts 3 are formed on a side wall 4b of each of the rail element members 4a, and a cover plate 24 is removably provided for covering these cut parts 23. After the rail element members 4a are connected in the longitudinal direction, the cover plate 24 is removed and the travelling member is mounted from the cut parts 23. In this way, since the travelling member can be easily mounted independent of the execution of the rail 4, higher executability can be obtained as compared with being executed in a state of mounting the travelling member on the rail 4.
