Further, when the operation knob 11 is slid, the cylindrical stopper column portion 46 is relatively slid within the guide recess 34 of the engagement leg portion 30 to guide the movement of the operation knob 11.

Further, in such an assembled state, the engaging leg 30 can be rotated (tilted) around 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 recess 34 is positioned coaxially with the shaft portion 32, the tilting operation is smoothly guided.

As shown in FIG. 3, the front fin 41 assembled with the operation knob 11 and the engaging leg 30 as described above is fitted with the support shafts 42 on both sides in the bearing portions provided on the both side walls in the second retainer 3. At this time, the leg portion 33 of the engagement leg portion 30 is engaged with the engagement shaft portion 53 at the front portion of the rear fin 51 assembled on the upstream side in the second retainer 3 as shown in FIG. Match.

In the register having the operation knob device 10 having the above-described configuration, when the operation knob 11 is rotated downward, the front fin 41 tilts downward about the support shaft 42 as shown in FIG. The direction is directed downward. At this time, the engagement leg portion 30 at the rear portion of the operation knob 11 rises so as to allow the operation knob 11 to rotate, and tilts downward in a substantially square shape around the shaft portion 32.

On the other hand, when the operation knob 11 is turned up, the front fin 41 tilts upward about the support shaft 42 as shown in FIG. 13C, and the air blowing direction is directed upward. At this time, the engagement leg portion 30 at the rear portion of the operation knob 11 is lowered so as to allow the operation knob 11 to rotate, and is tilted upward in the shape of a substantially square with the shaft portion 32 as the center.

On the other hand, when the operation knob 11 is slid to the right on the front fin 41, the operation knob 11 and the engagement leg 30 are moved to the right 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 rattling or abnormal noise. The sliding operation can be performed with a very good feeling.

At this time, the stopper cylindrical portion 46 slides well in the guide concave portion 34 and the end of the guide concave portion 34 abuts the end portion of the stopper cylindrical portion 46 at the moving end, so that the operation knob 11 stops. The problem that the operation knob 11 moves beyond the limit range is prevented.

By the sliding operation of the operation knob 11, the rear movable louver 5 causes each rear fin 51 to receive a rightward turning force via the leg portion 33 and the engagement shaft portion 53 of the engagement leg portion 30 and rotate to the right side. And the air blowing direction is directed to the right side.

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 engaging leg 30 are moved to the left as shown in FIG. The rear fin 51 receives the turning force to the left side through the leg part 33 and the engagement shaft part 53 of the engagement leg part 30 and rotates to the left side, so that the blowing direction is directed to the left side. 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 a sliding operation with a good feeling of feeling.

Also at this time, the stopper cylindrical portion 46 slides well in the guide concave portion 34, the end of the guide concave portion 34 abuts the end of the stopper cylindrical portion 46 at the moving end, and the operation knob 11 stops. Therefore, the trouble 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 portion 30 that is pivotally supported by the rear portion of the operation knob 11. Since the operation knob 11 is integrally formed of synthetic resin, it can be easily assembled at the time of manufacture, and even if an error within a 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 operation knob 11 can be prevented from being unstable due to dimensional tolerances, and the operation knob device 10 having stable performance can be manufactured.

Further, in the assembled state, the stopper cylindrical portion 46 is positioned in the guide concave portion 34 between the shaft portions 32 of the engaging leg portion 30, so that the stopper cylindrical portion 46 is good in the guide concave portion 34 during the sliding operation of the operation knob 11. And 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 is stopped. Therefore, the sliding operation range of the operation knob 11 is relatively simple. Depending on the structure, it can be set accurately.
