PROBLEM TO BE SOLVED: To provide an air diffuser capable of being inexpensively manufactured and easily regulating an air diffusing amount. SOLUTION: The air diffuser is constituted to have a body 11 and a regulator 12 integrally molded by resins. The body 11 has an air outlet 16 including a guide cylinder 13 and a diffusing guide 15. The regulator is disposed in the outlet 16. The regulator has a wind direction regulating plate 25 flared perpendicularly to an air diffusing direction in the outlet 16, and coupling plates 26, 27 extended from the plate 25 and inserted into the cylinder 13. A fine iregularities 29 is formed on the plate 27 in an inserting direction, and small protrusions 31 to be engaged with the iregularities 29 are formed on an inner surface of the cylinder 13. Accordingly, when the plate 25 is operated by a hand to be vertically displaced, the regulator is locked to an arbitrary position, and an opening area of a passage 28 is changed. Thus, a diffused air flow rate from the outlet 16 can be regulated. |
