Then, external air is blown into the internal space 1A from the air supply port 1B through the suction port 16A and the discharge port 10B via the hose 7, and external air is blown into the internal space 1A of the costume bag 1 to wear it. The bag 1 expands greatly like a balloon.

  If the person M performs various operations in this state, the costume bag 1 performs the same operation. For this reason, the air-bloomed costumes excite events and the like by the appearance of the mascot character, for example, by events such as familiarity, fun, and healing. Moreover, in this blowing type costume, since the blower 3 takes outside air into the internal space 1A, it is possible to relieve the discomfort felt by the person.

  During this time, the blower 3 is reduced in weight as a part of the main body case 10 is made of polypropylene cardboard, and supports the motor 30 and the hose 7. Further, since the battery 5A is contained in a battery case 5B made of polypropylene cardboard, the battery device 5 is also lighter than before.

  For this reason, even if a person in the interior space 1A of the costume bag 1 moves around while wearing the blower 3 for a long time, the person hardly feels a burden or fatigue due to the weight of the blower 3. For this reason, the movement of the person M is difficult to slow down, and the movement of the costume bag 1 is also difficult to slow down. For this reason, the image of friendliness, fun, healing, etc. that the mascot character has is fully exhibited.

  Therefore, in this air blower 3, it is hard to spoil the image of a mascot character.

( Reference example )
As shown in FIG. 5, in the air blower 4 of the reference example , most of the main body case 60 is made of a porous plastic plate material. This porous plastic plate material is light enough to support the motor 30 and the hose 7 while being as light as the polypropylene cardboard of the first embodiment. Other configurations are the same as those of the first embodiment. About the same structure as Example 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

In the air blower 4 of the reference example , the main body case 60 is further reduced in weight, and thus has a more remarkable effect.

In the above, the present invention has been described with reference to the first embodiment. However, the present invention is not limited to the first embodiment, and it is needless to say that the present invention can be appropriately modified and applied without departing from the spirit of the present invention. .

For example, as the porous plastic, in addition to polypropylene cardboard, a foamed polystyrene plate material, a foamed polyurethane plate material, or the like can be used. If it is difficult to support the hose or the motor only with the porous plastic plate material of the main body case, a solid plastic plate material such as vinyl chloride is integrated .
