PROBLEM TO BE SOLVED: To inhibit loss due to air flow turbulence at the resin inducer, particularly impact loss of the tip portion of the inlet, and inhibit turbulence of the flow of the internal duct. SOLUTION: The thickness of a blade portion 25a of a resin inducer 25 is made approximately the same thickness as a sheet metal blade 24 at the connecting portion thereof so that they connect smoothly, gradually becoming thinner toward the inlet 23a side. Therefore the impact with the blade is small at the tip portion of the inlet 23a, and further, the sheet thickness gradually becomes equivalent to that of the sheet metal blade 24. As a result, the air is able to flow smoothly, inhibiting loss and enabling high intake performance to be achieved.
