PROBLEM TO BE SOLVED: To provide a ventilation fan packaging device which is made wholly of corrugated board and which can pack a large mass, pressure-applying ventilation fan without being inverted. SOLUTION: The large mass, pressure-applying ventilation fan 1, constructed such that an impeller in the center of a square mounting frame is rotated by a motor supported by four mounting legs extending along the diagonals of the mounting square frame, is warped in the packaging device formed from corrugated board. A bottom holder 9 disposed on the bottom of a lower box 8 that is made of corrugated board and is open at the top keeps the pressure-applying ventilation fan 1 loaded with the motor facing down. The bottom holder 9 has fitting parts 14 that fit in the four corners of the lower box 8. Upward projections 15 for surrounding each mounting leg are formed at both ends of each fitting part 14. The upward projections 15 include support portions 17 for supporting the mounting square frame in contact with the back face of the mounting square frame. Receiving partitions 22 made of corrugated board and used to support the shapes of upward projections 15 are fitted on the upward projections 15. COPYRIGHT: (C)2007,JPO&INPIT
