The two top walls 413 are separated from each other by the end connected to the two side walls 412. . One side of the two top walls 413 and one side of the bottom wall 411 are disposed facing each other.

The bottom wall 411, the two side walls 412, and the two top walls 413 are collectively formed with a sliding space SP. In other words, one side of the outer rail 41 is concavely formed with a sliding space SP. In the present embodiment, the bottom wall 411, the two side walls 412, and the two top walls 413 are integrally formed. For example, it may be formed by appropriately bending a single sheet steel material.
