PROBLEM TO BE SOLVED: To provide a hanger rack including a support arm and a support arm of a hanger rack whose packing volume can be reduced. A support arm includes an upper support arm 11 and a lower support arm 12. The upper support arm and the lower support arm have a positioning hole 121 and a connection hole 122 on opposite surfaces. The positioning holes of the upper support arm and the lower support arm are positioned and connected by the positioning member 15. As a result, the connection holes of the upper support arm and the lower support arm are aligned to form a connection member mounting path. On the side surfaces of the upper support arm and the lower support arm, openings 111 and 123 that communicate with the connection member mounting path are provided. The first connecting member 13 is installed in the connecting member mounting path, and both ends of the first connecting member are exposed from the openings. A second connecting member 14 is installed in the opening. The second connecting member comes into contact with the first connecting member and positions the first connecting member in the extending direction of the connecting member mounting path.
