A drum type flag hoisting apparatus is provided to form a winding drum by connecting a first winding member and a second winding member having a bigger external diameter than the first winding member and a groove, thereby preventing generation of a folded mark on a flag. A drum type flag hoisting apparatus comprises a supporting frame(10), a winding drum(20), a driving motor(30), and a wire rope(40). The winding drum is installed to the supporting frame to rotate. The driving motor is connected to the winding drum. The winding drum has a cylindrical shape and consists of a first winding member(21) and a second winding member(22). The wire rope is wound around the first winding member. The second winding member has a bigger external diameter than the first winding member, and a groove for inserting a supporting pole(3) of a flag is formed in a length direction of the second winding member. The flag is wound around the second winding member. |
