Eachrear coupler lever 26 extends from the upperrear support shaft 25 of one of therear deflector plates 24. The distal ends of the rear coupler levers 26 are coupled to one another by a connector, which is arear connector rod 27. Therear connector rod 27 permits therear deflector plates 24 to pivot synchronously. - As described above, the plane of the opening14 a of the
duct 14 is inclined relative to the upper and lower surfaces of theduct 14. Also, the axes of therear deflector plates 24 are inclined and parallel to the plane of the opening 14 a such that therear deflector plates 24 are located close to thefront deflector plates 20. Chamfers 24 a are formed in the upper rear portion and the lower front portion of eachrear deflector plate 24. Thechamfers 24 a prevent the upper and lower surfaces of theduct 14 from interfering with therear deflector plates 24. - A
knob 28 is coupled to the center one of thefront deflector plates 20. Theknob 28 is slid in the lateral direction along the associatedfront deflector plate 20. A pair of engagingprojections 29 extends rearward from theknob 28. The center one of therear deflector plates 24 has an engagingpin 30. Theprojections 29 engage thepin 30 and move along the associatedrear deflector plate 24. - When the
knob 28 is moved vertically, thefront deflector plates 20 are synchronously pivoted through thefront connector rod 23. Accordingly, the direction of air blown out of the opening 14 a is vertically changed. When theknob 28 is moved horizontally, therear deflector plates 24 are synchronously moved through therear connector rod 27. Accordingly, the direction of air blown out of the opening 14 a is changed horizontally. - The
front deflector plates 20, thefront support shafts 21, the front coupler levers 22, thefront connector rod 23 and thefront duct member 14A are formed in a single double molding process. Thefront deflector plates 20, thefront support shafts 21, and the front coupler levers 22 are made of a thermoplastic resin having a relatively high melting point such as acrylonitrile butadiene styrene resin (ABS) . Thefront duct member 14A and thefront connector rod 23 are made of resin such as polypropylene (PP), the melting point of which is lower than that of the resin of thefront deflector plates 20, thefront support shafts 21 and thefront coupler lever 22. The resin of thefront duct member 14A and thefront connector rod 23 does not adhere to the resin of thefront deflector plates 20, thefront support shafts 21 and the front coupler levers 22. As described above, double molding refers to a method for molding an article using two resins that have different melting points. - The
rear deflector plates 24, theshafts 25, the rear coupler levers 26 and therear connector rod 27, and therear duct member 14B are formed in a single double molding process. Therear deflector plates 24, therear support shafts 25, the rear coupler levers 26 are made of a thermoplastic resin having a relatively high melting point such as acrylonitrile butadiene styrene resin (ABS). Therear duct member 14B and therear connector rod 27 are made of a resin such as polypropylene (PP), the melting point of which is lower than that of the resin of therear deflector plates 24, theshafts 25 and the rear coupler levers 26. The resin of therear duct member 14B and therear connector rod 27 does not adhere to the resin of therear deflector plates 24, therear support shafts 25 and the rear coupler levers 26. - As shown in FIG. 3, the
front duct member 14A, in which thefront deflector plates 20 are formed, and therear duct member 14B, in which therear deflector plates 24 are formed, are engaged with each other through the engagingrims knob 28, which is separately molded, is attached to the corresponding one of thefront deflector plates 20. - A procedure for double molding the
front duct member 14A will now be described with reference to FIGS. 4 and 5. - In a first step shown in FIG. 4, a first
stationary die 41A, a firstmovable die 42A, a firstleft slide core 43A and a firstright slide core 44A define frontdeflector plate cavities 45, frontsupport shaft cavities 46 and frontcoupler lever cavities 47. - ABS, the melting point of which is two hundred and ten degrees centigrade, is injected into the
cavities front deflector plates 20, thefront support shafts 21, the front coupler levers 22 are simultaneously formed. After thefront deflector plates 20,front support shafts 21 and the front coupler levers 22 are cooled, the firstmovable die 42A and theslide cores front deflector plates 20,front support shafts 21 and the front coupler levers 22 are removed from the dies 41A, 42A. - In a second step, which is shown in FIG. 5, the
front deflector plates 20,front support shafts 21 and the front coupler levers 22, which were molded in the first step, are inserted between a secondstationary die 41B and a secondmovable die 42B. Thefront deflector plates 20, the secondstationary die 41B, the secondmovable die 42B, a secondleft slide core 43B, a secondright slide core 44B and anupper slide core 48 define aduct cavity 49 and arod cavity 50. PP, the melting point of which is one hundred and seventy degrees centigrade, is injected into thecavities front duct member 14A and thefront connector rod 23 are formed simultaneously. After thefront duct member 14A and thefront connector rod 23 are cooled, the secondmovable die 42B and theslide cores 44 B 48 are moved outward. Then, thefront duct member 14A and thefront connector rod 23 are removed from the dies 41B, 42B. - In this manner, the
front deflector plates 20, thefront support shafts 21 and the front coupler levers 22 are molded with ABS, which has a relatively high melting point, in the first step. Thereafter, thefront duct member 14A and thefront connector rod 23 are molded with PP, which has a relatively low melting point, in the second step. - ABS and PP do not adhere to each other. Thus, in the second step, the parts formed in the first step do not stick to the parts formed in the second step. After the molding, the
front deflector plates 20 are pivotal with respect to thefront duct member 14A. - The
front duct member 14A, which includes thefront deflector plates 20, is easily formed by double molding.
