To obtain a large amount of aromatic blowing while increasing the volume of an aromatic storing part by arranging an air reserving part at just upstream side of a sucking port in a blow chamber where a fan for sucking and blowing-out an aroma which is discharged from the aromatic storing part is disposed and permitting an air intake passage having the aromatic storing part to communicate with the air reserving part.

When the fan 26 is driven by a motor 24, air is sucked from the sucking port 36 to the blow chamber 35 by way of the air intake passage 48 from the air intake port 47 of a cover 42. Simultaneously, the aroma in an aromatic storing cassette 41 is sucked from the port 36 to the chamber 35 through an aromatic intake passage 49 passing the entrance 43A and the exit 43B of the cassette 41 from the air intake port 47 of the cover 42. As a result, the aroma is generated in the chamber 35 and blown-out to the outside of the chamber from the blow-out port 37 of a blow case 12. In this case, the recessed air reserving part 51 is arranged at the just upstream side of the intake port 36 of the chamber 35 and also the narrow air intake passage 48 arranged between the cassette 41 and the cover 42 is made to communicate with the air reserving part 51.
