<P>PROBLEM TO BE SOLVED: To provide a ventilation device in which a duct for inhibiting a short circuit is easily arranged and furthermore excellent ventilation performance is obtained. <P>SOLUTION: One path of an air supply path P1 and an exhaust path 2 has a route in which air sucked through one suction port of an outside air suction port 61 and an exhaust suction port 63 into a casing 21 passes through a first element 41 and then passes through a second element 42. The other path has a turning route in which air sucked through the other suction port of the outside air suction port 61 and the exhaust suction port 63 into the casing 21 flows into one side plate 25 side other than the first element 41 by an alternative route B that does not pass through the first element 41, passes through, in first, the second element 42 and then returns to the other side plate 24 side and passes through the first element 41. <P>COPYRIGHT: (C)2012,JPO&INPIT |
