Claims

[Scope of utility model registration request]

This is a ventilation device that performs ventilation in a sealed room while blocking external light, and includes a plurality of fans that are rotatably driven around a coaxial core, and are provided with a plurality of fans rotatably driven around a coaxial core at the ventilation opening to the sealed room. A cylindrical light shielding portion is provided on the outer periphery of the fan, blades of the fan are provided in a state that mutually interrupts the linear optical path from the opening, and the fan is driven and rotated while maintaining the light shielding state. It consists of a ventilation system.
