PROBLEM TO BE SOLVED: To provide a ventilation fan packaging device capable of reducing the use of packaging members, facilitating packaging work, and reducing cost by providing a structure for distributing loads by increasing the number of effectively supporting parts for supporting the loads during stacking storage. SOLUTION: In the packaging device 10 for the ventilation fan 1, an orifice 3 is formed in an attaching square frame 2, and an impeller 6 is rotated in the orifice 3 by a motor 5 supported by an attaching arm 4 extending to a back surface side along the diagonal of the attaching square frame 2. The packaging device 10 has a square lower box 11 in which the ventilation fan 1 is loaded on a bottom plate 12 with the attaching square frame 2 being the lower side, a square prismatic side surface frame 21 with its lower end fitted to the lower box 11 to cover the outer periphery of the ventilation fan 1, and an upper box 31 to cover an upper end of the side surface frame 21. Girders 13a, 13b, 14a and 14b are provided at the lower side of the bottom plate 12 of the lower box 11 along four sides thereof. COPYRIGHT: (C)2011,JPO&INPIT
