A box of the packing device includes side surface portions, upper flaps, lower flaps, a protrusion, a fixing portion, and interior cushions. The protrusion is formed by folding part of an upper flap. The fixing portion fixes the protrusion such that the protrusion projects from the upper flap. In a state where an object is accommodated in the box, the protrusion is interposed between the upper flap and the packed object, and disperses the load applied to the box. ## Claims ### Claim 1 A packing device for packing an object, comprising: a box formed of at least one corrugated board sheet for accommodating the object, the box having a top surface portion, a bottom surface portion opposite to the top surface portion and a side surface portion connecting the top surface portion and the bottom surface portion to each other;
