The rail part 100 is a hollow shaft of a cross hollow cross section, and has a length of 1.5-3 m corresponding to the protruding edge of the rear plate 4 of the side cell 3 of the container ship upper deck. The weight is 3 kg on the basis of 1.5 m.

The rail portion 100 is made of aluminum and is subject to normal aluminum drawing.

The rail unit 100 has an upper protrusion 101, both side protrusions 102 and 103, and a lower protrusion 104.

Here, with respect to the center, the upper protrusion 101 and the lower protrusion 104 has a short width distance, preferably shorter than the long width distance between the both side projections (102, 103).

The upper protrusion 101 and the lower protrusion 104 of such a short width distance are disposed in the vertical direction, and both side protrusions 102 and 103 of the long width distance are preferably disposed in the left-right direction (horizontal direction).

The upper protrusion 101 is formed with a groove 105 bent in the center thereof along the axial direction. The bending groove 105 fixes the rack gear 110 (hereinafter referred to as a 'rack') in the axial direction of the rail part 100 by a conventional fixing method such as an interference fit method, stud bolt fixing, or welding. .
