The lower ends of the air guide parts 9, 10 are bent downstream to form rectifying parts 11, 12 which are continuous with the upper wall immediately before the air outlet ports 6, 7 disposed immediately after the lower ends. The rectifiers 11 and 12 prevent turbulence from occurring at the rear of the wind guiding section. Due to the formation of the wind guiding sections 9, 10 and the rectifying sections 11, 12, recesses 13, 14 having different depths are formed in the upper wall 4. Ribs 15, 1 having mounting holes 15a, 16a are provided in the recesses 13, 14 along the longitudinal direction of the duct 1.
6 is formed. The ribs 15 and 16 are used as attachment parts for attaching the duct to the vehicle body, and are connected and fixed to vehicle body structures or brackets indicated by reference numerals 17 and 18. In the illustrated example, rib 1
5 and 16 are provided at the center of the recess, but they may be provided offset to one side in the duct width direction.

The duct 1 has an air inlet 2 communicated with a fan duct (not shown), and its ribs 15 and 16 are fixed to the body. The air sent from the air introduction port 2 of the duct 1 flows in the direction shown by the arrow, and a part of the air is blown out from the air outlet 5 by the air guide section 9 and narrowed by the air guide section 9. The air that has passed through the passage is passed through the air outlet 6 by the air guide section 10.
The remaining air is blown out from the air outlet 7. At this time, the air introduced from the air inlet 2 is narrowed as the passage area of the duct goes downstream, so the air outlet 5, 6, 7
The amount of air blown out is approximately equal. In addition, the air that has passed between the wind guide section 9 and the bottom wall 8 is
It is guided by the rectifying section 11 and heads downstream without causing turbulence at the rear of the wind guiding section. The air that has passed between the wind guiding section 10 and the bottom wall 8 is also guided by the rectifying section 12, so that it heads toward the air outlet 7 without causing turbulence.

(Effect of the invention) Since the air guide section is set to narrow the duct passage area S toward the downstream side, the duct passage area S of the downstream air guide section is narrower than the upstream air guide section. Depending on the amount, the amount of air blown from each air outlet can be made equal or different. Furthermore, by providing each air outlet with a rectifying section that extends in a substantially arc shape toward the upstream side of the air outlet located downstream from the inner end of the duct of the air guide section, the air guide section is improved. Turbulent flow generated near the inner end of the duct can be prevented, and noise caused by the turbulent flow can be reliably suppressed. Furthermore, a rib is provided integrally along the longitudinal direction of the duct in the concave portion formed on the outside of the duct by the wind guide section and the rectifying section, and has a mounting hole for attaching the duct to the vehicle body. , the strength of the duct is increased, and when the duct is attached to the vehicle body, there is no need for a mounting member to connect the duct and the vehicle body, reducing the number of parts and reducing costs. Installation work becomes easier. Furthermore, since the ribs are provided in the recesses formed on the outside of the duct, the ribs do not protrude from the duct, and the mounting location of the duct is not limited.
