The air intake system 21 includes a fan 57 and a first perforated panel 40 is attached to the exhaust opening 28. The first panel 40 includes a convex portion 71 located at the back in the anteroposterior direction A of the air intake system 21, a concave portion 72 located in front of the convex portion 71, and an intermediate portion 73 which connects the convex portion 71 to the concave portion 72. A plurality of first air holes are formed in at least one of the convex portion 71 and the concave portion 72 and in the intermediate portion 73. COPYRIGHT: (C)2012,JPO&INPIT |
