  Further, in this state, the load applying member 8 in the operation knob 11 causes the convex portion to abut on the front edge of the front fin 41 with an appropriate elastic load, and the guide rib 43 on the rear edge of the front fin 41 engages with the engaging leg. This is in a state of contact with the outer peripheral portion of the shaft portion 32 of the portion 30. For this reason, the operation knob 11 is slidably attached to the front fin 41 without rattling, and at the time of sliding, an appropriate frictional resistance is generated between the load applying member 8 and the front fin 41, and the operation knob 11 has an appropriate An operation load is applied, and the device is slidably mounted.

  When the operation knob 11 is slid on the front fin 41 in such an assembled state, when the operation knob 11 is slid rightward as shown in FIG. When the operation knob 11 is slid leftward as shown in FIG. 15, the inside of the right shaft 32 is brought into contact with the right end of the stopper column 46. Stop by touching. For this reason, the sliding range of the operation knob 11 is set by the stopper cylinder 46. Further, when the operation knob 11 slides, the cylindrical stopper cylinder 46 relatively slides in the guide recess 34 of the engagement leg 30 to guide the movement of the operation knob 11.

  Further, in such an assembled state, the engaging leg 30 can rotate (tilt) about the shaft portions 32 on both sides with respect to the front fin 41 and the operation knob 11. Since the stopper cylindrical portion 46 in the concave portion 34 is located coaxially with the shaft portion 32, the tilting operation is smoothly guided.

  As shown in FIG. 3, the front fins 41 to which the operation knob 11 and the engaging leg 30 are assembled as described above fit the support shafts 42 on both sides into bearings provided on both side walls in the second retainer 3. At this time, the leg 33 of the engaging leg 30 is engaged with the engaging shaft 53 at the front of the rear fin 51 assembled on the upstream side in the second retainer 3 as shown in FIG. Combine.

  When the operation knob 11 is rotated downward, the register provided with the operation knob device 10 having the above configuration causes the front fin 41 to tilt downward about the support shaft 42 as shown in FIG. The direction is directed downward. At this time, the engagement leg 30 at the rear of the operation knob 11 rises so as to allow the rotation of the operation knob 11, and tilts downward about the shaft 32 in a substantially rectangular shape.

  Conversely, when the operation knob 11 is turned upward, as shown in FIG. 13C, the front fin 41 is tilted upward about the support shaft 42, and the blowing direction is directed upward. At this time, the engagement leg 30 at the rear of the operation knob 11 is lowered so as to allow the rotation of the operation knob 11, and is tilted upward in a substantially rectangular shape around the shaft 32.

  On the other hand, when the operation knob 11 is slid rightward on the front fin 41, the operation knob 11 and the engaging leg 30 move rightward as shown in FIG. At this time, the load applying member 8 in the operation knob 11 and the front fin 41 are in sliding contact with appropriate frictional resistance, and an appropriate operation load is applied thereto, so that the user can smoothly move without generating rattling or noise. The sliding operation can be performed with a good feeling.

  At this time, the stopper column 46 slides favorably in the guide recess 34, and the end of the guide recess 34 contacts the end of the stopper column 46 at the moving end, so that the operation knob 11 stops. In addition, it is possible to prevent the operation knob 11 from moving beyond the limit range.

  By the sliding operation of the operation knob 11, the rear movable louver 5 receives the turning power to the right through the rear fins 51 via the leg 33 of the engaging leg 30 and the engaging shaft 53, and turns to the right. And the air blowing direction is directed to the right.

  On the other hand, when the operation knob 11 is slid to the left on the front fin 41, the operation knob 11 and the engagement leg 30 move to the left as shown in FIG. The rear fin 51 receives the turning force to the left via the leg 33 of the engaging leg 30 and the engaging shaft 53, rotates to the left, and the blowing direction is directed to the left. At this time, similarly to the above, the load applying member 8 in the operation knob 11 and the front fin 41 are in sliding contact with an appropriate frictional resistance, and the user can smoothly perform the sliding operation with a good feeling.

  Also at this time, the stopper cylinder 46 slides favorably in the guide recess 34, and the end of the guide recess 34 contacts the end of the stopper cylinder 46 at the moving end, and the operation knob 11 stops. Therefore, a problem that the operation knob 11 moves beyond the limit range is prevented.

  As described above, the operation knob device 10 having the above-described configuration includes the operation knob 11 that is slidably fitted on the front fin 41 and the engagement leg 30 that is rotatably supported at the rear of the operation knob 11. Since the operation knob 11 is integrally formed of synthetic resin, the operation knob 11 can be easily assembled at the time of manufacturing, and even if an error within the dimensional tolerance occurs, the error of a plurality of parts is added up and operated. The dimensional error of the knob does not increase, and the fitting dimension (fitting state) between the operation knob 11 and the front fin 41 is constant. For this reason, the occurrence of rattling due to dimensional tolerances in the operation knob 11 is prevented, and the operation knob device 10 having stable performance can be manufactured.

  In addition, in the assembled state, the stopper cylinder 46 is located in the guide recess 34 between the shafts 32 of the engagement legs 30, so that when the operation knob 11 is slid, the stopper cylinder 46 is good in the guide recess 34. At the same time, the end of the guide recess 34 comes into contact with the end of the stopper cylinder 46 at the moving end, and the operation knob 11 stops. Therefore, the sliding operation range of the operation knob 11 is relatively simple. Depending on the structure, it can be set accurately.
