Abstract: <P>PROBLEM TO BE SOLVED: To provide an air duct capable of maintaining strength as a cross member while improving air distribution performance.  <P>SOLUTION: Since the opposed wall of an inlet 21 is configured to be protruded to the inlet 21 side as a protruded airstream straightening part 31 having a pair of tilting walls 33, 33 tilting toward both sides L, R in the car width direction, the airstream from the inlet 21 is smoothly distributed to discharge ports 27L, 29L, 27R, 29R on both sides L, R by the distributing function of the airstream straightening part 31. As a result, the air distribution performance of the air duct 20 is improved. Furthermore, since a rib 35 (reinforcing member) connecting the walls 33, 33 on both sides straddling the top 31a of the airstream straightening part 31 is provided, rigidity around the airstream straightening part 31 is supplemented. Thus, the air duct 20 can maintain rigidity as a cross member while improving air distribution performance.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
