<p>PURPOSE: To prevent a blown air direction-adjusting device from influencing against discharged air and reduce any operating noise generated at vanes, by a method wherein a turning operation of hinge pins capable of pivotally supporting each of the blades turned right and left is supported and many hinge pins are integrally connected to each other. CONSTITUTION: A lower stage of each of right and left adjusting vanes 20 is formed with a lower pin 22 fitted to a hole 13a. In turn, an upper pin 21 is projected and formed on a straight line together with the lower pin 22 at an upper stage of each of the right and left adjusting vanes 20. Further, an upper plate 12 and a fixing member 14 coupled to the upper plate 12 are formed with each of pin receptors 12a, 14a for rotatably supporting each of the upper pins 21. Then, each of the upper pins 21 is provided with a connecting member 30 for connecting each of the upper pins so as to cause each of the right and left adjusting vanes 20 to be cooperatively operated. Such a connecting member 30 as above is constituted by protrusions 31 formed at each of the upper pins 21 so as to be projected out toward the fixing member 14, and by a connecting part 32 for connecting each of the protrusions 31.</p> |
