Claims

[Scope of utility model registration request]

The main body frame has a ventilation blower built into the exhaust passage that is open at the front and rear ends, and the front and rear ends are open in addition to the exhaust passage, forming an air supply passage that allows natural ventilation, and is attached to the front of the main body frame. In addition to the suction port that constitutes the inlet end of the exhaust passage of the main body frame, a communication passage communicating with the air supply passage is formed in the front frame in which the front panel is opposed to each other at a distance with a support structure. The ventilation fan is characterized in that the communication passage passes through the support structure of the front frame and opens forward to the front of the front panel.
