PROBLEM TO BE SOLVED: To provide an air conditioning apparatus suppressing ventilation resistance without passage of a test finger. SOLUTION: The air conditioning apparatus includes a casing 4, an air conditioning fan 31 and a fan guard 46. The air conditioning fan 31 is stored in the casing 4. The fan guard 46 prevents contact with the fan 31, and includes a ventilation hole 46b. Air sent out from the fan 31 or sucked to the fan 31 is made to pass through the ventilation hole 46b. The ventilation hole 46b is formed by combining regular hexagonal openings OP2, and the diameter of a circumscribed circle of the opening is set to be 10 mm or more. COPYRIGHT: (C)2010,JPO&INPIT |
