Abstract: An article transport facility includes a transport vehicle configured to travel on a travel surface on each of a plurality of travel floors. The transport vehicle is configured to travel straight and to change directions by executing turning movement to turning about an axis in the up-down direction on a spot. Columns extend through the travel floors in the up-down direction and protrude upward of the travel surface. Each travel floor has column through holes that are for the columns to extend through. The column through holes do not overlap a first straight path, a second straight path, and a turning path as viewed in the up-down direction, and overlap at least either a first tangent line or a second tangent line.

Abstract: An article transport facility includes support columns (2) and support beams (5) that are coupled to the support columns (2) and support rails (7). The support beams (5) each include a beam body (50), attachment members (55) for attachment to the support columns (2), and support members (60) that are fixed to the beam body (50) and are for supporting the rails (7). A support beam (5) and a support column (2) are coupled together by locking portions (59) provided on the attachment members (55) being locked to lock receiving portions (21) formed in the support column 2, and by binding with use of first binding members (B1) inserted through first through holes (66) formed in the support members (60).
