  The operation of the gear mechanism 33 is first performed when the rotating fin body 40a of the rotating fin 40 is in a horizontal state along the ventilation direction A, that is, in a neutral position, as shown in FIG. The gear 53 is also in the neutral position, the pin 58 of the upper fin 41 is located at the corner of the front end of the first link groove 53e, and the pin 58 of the lower fin 42 is located at the corner of the front end of the second link groove 53f. The upper fin 41 and the lower fin 42 are located at the front end of the movement range. In this neutral state, that is, the neutral state, the rotating fin 40 is horizontal, and the guide plate portions 41b and 42b of the upper fin 41 and the lower fin 42, that is, the guide surface portions 41c and 42c are substantially symmetrical with respect to the rotating fin 40. The surface connecting the tips of the fins 40, 41, and 42 is close to the air outlet 18 and parallel or substantially parallel to the air outlet 18, and the air supplied by the air conditioner is forward from the air outlet 18. Blow horizontally.

  Here, from the neutral state, as shown in FIG. 1A, the operation knob 40c is picked and turned so that the front side of the turning fin body 40a of the turning fin 40 faces upward. Then, the rotation of the rotation fin 40 is transmitted from the first gear 51 to the third gear 53 via the second gear 52, and the link grooves 53e and 53f of the third gear 53 are transmitted in the same direction as the rotation fin 40.

On the other hand, the pin 58 of the lower fin 42 is in a place where the radius of the second link groove 53f is constant, and the lower fin 42 does not move backward from the front end. In this state, the air supplied by the air conditioner is first bent downward by the first guide surface portion 41c of the upper fin 41 on the upper side of the rotating fin 40, as indicated by the arrow F1, and It strikes against the first opposing surface portion 40e which is the upper surface, and is reliably guided upward by the rotating fin 40. On the other hand, on the lower side of the rotating fin 40, the air supplied by the air conditioner is, as shown by the arrow F2, the second opposing surface portion 40f and the lower fin which are the lower surfaces of the rotating fins 40 that are substantially parallel to each other. It is guided between the second guide surface portions 42c of 42 and reliably guided upward. In this way, the conditioned air is surely greatly bent above and below the rotating fin 40 and guided upward.

  On the other hand, as shown in FIG. 1C from the neutral state, the operation knob 40c is picked and rotated so that the front side of the rotation fin body 40a of the rotation fin 40 faces downward. Then, the rotation of the rotation fin 40 is transmitted from the first gear 51 to the third gear 53 via the second gear 52, and the link grooves 53e and 53f of the third gear 53 are transmitted in the same direction as the rotation fin 40. Turn it down somewhere. Then, the pin 58 of the upper fin 41 is in a place where the radius of the first link groove 53e is constant, and the upper fin 41 does not move from the front end. On the other hand, the pin 58 of the lower fin 42 is pushed backward by a portion where the radius of the second link groove 53f is reduced. In other words, the lower fin 42 moves rearward while sliding the lower fin base portion 42 a to the second surface portion 22. In this state, the air supplied by the air conditioner is above the first opposing surface portion 40e that is the upper surface of the rotating fins 40 that are substantially parallel to each other, as indicated by the arrow F3 above the rotating fins 40. It is guided between the first guide surface portion 41c of the fin 41 and reliably guided downward. On the other hand, on the lower side of the rotating fin 40, the air supplied by the air conditioner is first bent upward by the second guide surface portion 42c of the lower fin 42 as indicated by the arrow F4. It strikes against the second opposing surface portion 40f and is reliably guided downward by the rotating fin 40. In this way, the conditioned air is greatly bent and guided downward.

  Thus, according to the wind direction adjusting device of the present embodiment, the central rotating fin 40 provided with the operation knob 40c is set to the neutral position using the three fins 40, 41, 42 connected by the gear mechanism 33. , In conjunction with the rotation of the rotating fin 40, either the upper fin 41 or the lower fin 42 on the side facing the downstream edge of the rotating fin 40 is passed in the ventilation direction A. It was made to retreat to the upstream side along. Therefore, the wind is bent by the guide surface portions 41c and 42c provided by bending the retracted fins 41 and 42, and the bent wind is applied to the opposing surface portions 40e and 40f of the rotating fin 40 at a large angle to ensure the wind direction. The air distribution performance can be improved by greatly changing the air flow and suppressing the blow-through.

  Further, the upper fin 41 and the lower fin 42 do not rotate, and the first surface portion 21 that is the upper surface of the ventilation path 17 and the first surface that is the lower surface are associated with the rotation of the rotation fin 40 located in the center in the height direction. Since the sliding movement, that is, sliding, is performed while sliding along the surface portion 22 of the two, the air flow path 17 can be switched without being obstructed by being narrowed more than necessary and close to the upper and lower surface portions 21 and 22. Compared with the structure in which the fins are rotated, the height dimension can be suppressed, the apparatus can be thinned, and the blow-through flowing between the upper fin 41 and the lower fin 42 and the upper and lower surface portions 21 and 22 of the ventilation path 17, It is possible to prevent the accumulation of wind between the fins 41 and the lower fins 42 and the upper and lower surface portions 21 and 22 of the ventilation path 17, thereby improving the air distribution performance and preventing the generation of abnormal noise and improving the quality.

  Further, compared to the configuration using only fins that slide in directions opposite to each other, the rotation fin 40 is provided in the central portion, so that the overlap of the fins 40, 41, 42 can be increased when viewed from the ventilation direction A, and the rotation fin On the side to which the tip of 40 faces, the wind bent by the moved fins 41 and 42 is struck against the rotating fin 40 and bent securely, and on the opposite side of the rotating fin 40, the rotating fin 40 and the fins 41 and 42 The wind can be reliably bent by being parallel to each other, and it is easy to improve the wind distribution characteristics such as improving directivity.

  In addition, since the interlocking mechanism for transmitting the operation of the rotating fin 40 to the upper and lower fins 41 and 42 is constituted by three gears directly connected to the rotating fin 40 provided with the operation knob 40c, a structure using a link having a large longitudinal dimension. Compared to the above, there is no elastic deformation of the member, and the operational feeling can be easily improved.

  Further, since the first gear portion 51a, the second gear portion 52a, and the third gear portion 53a constituting the triple gear mechanism 33 are all arranged outside the ventilation path 17, the ventilation resistance is not increased. The air flow rate can be easily secured.

  Further, it can be constituted by a small number of fins 40, 41, and 42, so that the structure can be simplified and the manufacturing cost can be reduced.

  In addition, the ventilation path 17 does not need to be provided with a space that can accommodate a part of the rotating fin, and can be easily reduced in thickness, and the degree of freedom in layout can be improved.

  In addition, the characteristics can be easily adjusted by adjusting the angles and dimensions at which the guide surface portions 41c and 42c of the upper fin 41 and the lower fin 42 protrude from the base portions 41c and 42c. For example, even if the overlapping amount of the fins 40, 41, 42 seen from the ventilation direction A is small, the air guide characteristics 41b, 42c are greatly bent to improve the air distribution characteristics for bending the air and target directivity Can be secured.

  Moreover, since it has sufficient air distribution performance as described above, even if the surface of the instrument panel, which is a modeling surface on which the wind direction adjusting device 10 is installed, is inclined with respect to the ventilation direction A, the necessary air distribution performance Can be installed while securing.

  In this way, it is possible to secure sufficient air distribution performance without increasing the number of fins in a limited narrow space, and a thin type having long outlets 18 on both sides arranged in a restricted place such as an automobile instrument panel Thus, it is possible to provide the wind direction adjusting device 10 which is a so-called thin ventilator that can ensure sufficient air distribution performance with the case body 11.

  In the above embodiment, the number of fins is three. However, the present invention is not limited to this configuration. For example, two rotating fins 40 can be arranged on the top and bottom, and the horizontal louver 30 can be configured with a total of four fins.

  In the above embodiment, when the rotating fin 40 is rotated from the neutral state, one of the upper and lower fins 41 and 42 is retracted to the upstream side, but one is retracted and the other is advanced. You can also make it.

  The present invention can be applied, for example, to an air outlet device of an air conditioner provided in an instrument panel of an automobile.
