On the other hand, the rear side is rotated so as to move to the right side which is the other side. Therefore, the rear link to which the first link shaft portion 34 (link shaft portions 34a, 34b, 34c) located behind the first rotation shaft portion 33 (rotation shaft portions 33a, 33b, 33c) is coupled. 14 moves to the right, that is, in the direction opposite to the operation direction of the operation knob 17 (FIG. 3). Therefore, the second link shaft portion 44 of the second rear fin 13 that is loosely fitted to the second link bearing portion 54 of the rear link 14 slides rearward along the second link bearing portion 54, By moving to the right, which is the moving direction of the link 14, the second rear fin 13 is centered on the second rotating shaft 43 located behind the second link shaft 44, and the front side is on the right. It rotates so that the rear side moves to the left. That is, the first rear fin 12 and the second rear fin 13 rotate in directions opposite to each other.

  As a result, the first rear fin 12 (rear fins 12a, 12b, 12c) is tilted to the left and the second rear fin 13 is tilted to the right, so that the rear side of the right rear fin body 32c of the right rear fin 12c of the first rear fin 12 is the other side plate. While approaching (contacting) the portion 24, the rear side of the second rear fin body 42 of the second rear fin 13 approaches (contacts) one side plate portion 23. For this reason, in the ventilation path 26, the straight wind that flows along the position below the bearing portion 30 of the one side plate portion 23 is rectified by the second rear fin 13 toward the center side (right side) in the left-right direction. Directly blown to the left rear fin 12a of the rear fin 12, the left rear fin 12a rectifies leftward. At this time, the wind rectified by the left rear fin 12a is blown by the second rear fin 13 and bounces leftward from the left rear fin 12a because there is no louver on the left which is the direction of rectification by the left rear fin 12a. The wind bounces back to the right again and no turbulence is generated, and the air is reliably rectified to the left as it is. Further, the wind flowing through other positions of the ventilation path 26 is rectified toward the left by the rear fins 12a, 12b, and 12c of the first rear fin 12. Therefore, the entire wind passing through the ventilation path 26 is reliably rectified leftward without going straight forward from the outlet 27 or flowing rightward.

  On the other hand, from the neutral state shown in FIGS. 1B and 2B, the operation knob 17 (FIG. 3) is operated to the right side (the vehicle width direction outside) which is the other side (FIG. 1). (C) and FIG. 2 (c)), the first rear fin 12 (rear fins 12a, 12b, 12c) is centered on the first rotation shaft portion 33 (rotation shaft portions 33a, 33b, 33c), and the front side is on the right Rotate so that the rear side moves to the left. Therefore, the rear link to which the first link shaft portion 34 (link shaft portions 34a, 34b, 34c) located behind the first rotation shaft portion 33 (rotation shaft portions 33a, 33b, 33c) is coupled. 14 moves relatively to the left, that is, in the direction opposite to the operation direction of the operation knob 17 (FIG. 3). Therefore, the second link shaft portion 44 of the second rear fin 13 that is loosely fitted to the second link bearing portion 54 of the rear link 14 slides rearward along the second link bearing portion 54, By moving to the left which is the moving direction of the link 14, the second rear fin 13 is centered on the second rotating shaft 43 positioned behind the second link shaft 44, and the front side is on the left. It rotates so that the rear side moves to the right. That is, the first rear fin 12 and the second rear fin 13 rotate in directions opposite to each other.

  As a result, the first rear fin 12 (rear fins 12a, 12b, 12c) is inclined to the right and the second rear fin 13 is inclined to the left, so that the front side of the right rear fin body 32c of the right rear fin 12c of the first rear fin 12 is the other side plate. While approaching (contacting) the part 24, the front side of the second rear fin body 42 of the second rear fin 13 is approaching (contacting) the one side plate part 23, and the ventilation path 26 is blocked at these positions. For this reason, in the ventilation path 26, the straight air that flows along the position below the bearing portion 30 of the one side plate portion 23 is blocked by the second rear fin 13, and the straight air that flows along the other side plate portion 24 is The first rear fin 12 is blocked by the right rear fin 12c. Further, the wind flowing in other positions of the ventilation path 26 is rectified toward the right by the rear fins 12a and 12b of the first rear fin 12. Therefore, the wind passing through the ventilation path 26 is reliably rectified rightward, that is, in a direction away from the passenger (outside in the vehicle width direction) with a smaller air volume than when the operation knob 17 is operated to the left.

  Therefore, even when the operation knob 17 (FIG. 3) is operated in either the left or right direction, the wind is surely distributed left and right without going straight forward, and the air distribution performance (wind direction controllability) is ensured.

  On the other hand, when the operation knob 17 (FIG. 3) is operated up and down, the central front fin 15b shown in FIG. 5 directly rotates up and down around the central rotation shaft portion 63b. In this state, the front fins 15a and 15c connected to the central front fin 15b by the front link 16 rotate in conjunction with the central front fin 15b, and the wind direction is changed up or down, that is, adjusted.

  Therefore, the wind direction is adjusted in an arbitrary direction by operating the operation knob 17 up, down, left, and right.

  Thus, according to the present embodiment, the first rotating shaft portion 33 of the first rear fin 12 is pivotally supported on the case body 11 and the second rotating shaft portion 43 of the second rear fin 13 is supported. Is pivotally supported by the case body 11 on the windward side of the ventilation path with respect to the first rotation shaft part 33, and the wind of the ventilation path 26 with respect to the first rotation shaft part 33 of the first rear fin 12 is supported. The first link shaft portion 34 positioned on the upper side and the second link shaft portion 44 positioned on the leeward side of the ventilation path 26 with respect to the second rotation shaft portion 43 of the second rear fin 13 are rotated by the rear link 14. By connecting them in a possible manner, the first rear fin 12 and the second rear fin 13 can be interlocked and rotated in opposite directions with only a single rear link 14 without using a plurality of gears, for example. Therefore, good air distribution performance can be obtained without increasing the number of parts more than necessary.

  In addition, a bent portion 52 that bends in the upwind direction of the ventilation path 26 is provided at one end portion of the rear link body 51 of the rear link 14 that is disposed along the direction intersecting the rotation shaft portions 33 and 43. By connecting the bent portion 52 to the second link shaft portion 44 of the second rear fin 13, when the first rear fin 12 and the second rear fin 13 are rotated, The straight wind that flows along can be reliably controlled by the second rear fin 13 at a position upstream of the first rear fin 12, and the wind can be reliably blown out in a desired direction.

  In addition, since the second link bearing portion 54 that receives the second link shaft portion 44 of the second rear fin 13 so as to be rotatable and slidable can be formed in a long hole shape along the bent portion 52, the second rear fin 13 and the first The rotation stroke of the rear fin 12 can be made larger.

  Furthermore, the second rotating shaft portion 43 of the second rear fin 13 is positioned in the left-right direction intersecting the first rotating shaft portion 33 rather than the first rotating shaft portion 33 of the first rear fin 12. This side plate is located near one side plate portion 23 and is rotated in a direction (left side) in which the front side portion, which is the leeward end of the ventilation path 26 of the second rear fin 13, approaches the side plate portion 23. By closing the ventilation path 26 between the side plate 23 and the second plate 13, the straight wind that flows along the side plate portion 23 is surely blocked by the second rear fin 13 so that the straight wind does not go straight and blow through. Wind performance can be further improved.

  Further, since the straight wind flowing along one side plate portion 23 can be blocked by the second rear fin 13, one of the case bodies 11 as in the conventional example shown by the imaginary line L1 in FIG. 1 and the imaginary line L2 in FIG. Since the so-called wall-blocking setting in which the side plate portion 23 is crushed narrowly is not required, the effective opening of the case body 11 (ventilation passage 26) is widened, the ventilation resistance can be reduced, and the crushed wall from the occupant side (imagination in FIG. 3) The line L2) is not visible and the appearance can be improved.

  Furthermore, the second rear fin 13 is arranged in the vicinity of one side plate portion 23 that is relatively inward in the vehicle width direction in the ventilation path 26 of the case body 11, so that the direction away from the passenger side, this embodiment Then, it is possible to suppress the amount of unnecessary wind blowing to the right.

  In addition, an increase in the number of parts can be suppressed, and it is not necessary to provide a space for improving the air distribution performance between the first rear fin 12 and the second rear fin 13, and the case body 11 can be reduced in size.

  Next, a second embodiment will be described with reference to FIG. In addition, about the structure and effect | action similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted. Further, in order to clarify the explanation, the front fins 15 and the front links 16 are omitted in FIG.

  In the wind direction adjusting apparatus 10 of the present embodiment, two second rear fins 13 of the first embodiment are set, and the first rear fin 12 and the second rear fin 13 are arranged symmetrically. .

  Of the second rear fins 13, the left side closer to one side plate portion 23 is the left rear rear fin 13a, and the right side closer to the other side plate portion 24 is the right rear rear fin 13b. That is, the left rear rear fin 13a constitutes a left rear rear fin main body 42a constituting the second rear fin main body 42, a left rear rotary shaft 43a constituting the second rotary shaft 43, and a second link shaft 44. Left rear link shaft portion 44a, right rear rear fin 13b, right rear rear fin body 42b constituting second rear fin body 42, and right rear rotation shaft portion 43b constituting second rotation shaft portion 43. And a right rear link shaft portion 44b constituting the second link shaft portion 44.

  Further, the left rear rear fin 13 a is a left rear fin that constitutes the first rear fin 12 at a position where the left rear rotational shaft portion 43 a is spaced rearward from the first rotational shaft portion 33 of the first rear fin 12. It is arranged in the ventilation path 26 at a position closer to one side plate part 23 (leftward) than 12a. That is, the left rear rear fin 13 a is disposed at a position closer to one side plate portion 23 than the left rear fin 12 a constituting the first rear fin 12.

  Further, the right rear rear fin 13b is a right rear fin that constitutes the first rear fin 12 at a position where the right rear rotational shaft portion 43b is spaced rearward from the first rotational shaft portion 33 of the first rear fin 12. It is arranged in the ventilation path 26 at a position closer to the other side plate part 24 (rightward) than 12c. That is, the right rear rear fin 13b is arranged at a position closer to the other side plate portion 24 than the right rear fin 12c constituting the first rear fin 12.

  Further, the rear fins 13a and 13b of the second rear fin 13 are spaced apart from the rear fins 12a and 12c to the side by a distance substantially equal to the distance between the rear fins 12a, 12b and 12c of the first rear fin 12 in a front view. . Therefore, the rear fins 12 and 13 are spaced at substantially equal intervals in the left-right direction.

  Further, the rear link 14 has a first link bearing portion 53 (link bearing portions 53a, 53b, 53c) opened at a position near the front portion of an elongated plate-like rear link body 51 whose longitudinal direction is the left-right direction. In addition, a long hole-shaped second link bearing portion 54 having a longitudinal direction along the front-rear direction is opened at the rear portion of both end portions of the rear link body 51. Therefore, the second link bearing portion 54 includes a left rear link bearing portion 54a that receives the left rear link shaft portion 44a of the left rear rear fin 13a, and a right rear link bearing portion that receives the right rear link shaft portion 44b of the right rear rear fin 13b. 54b.

  Then, when the operation knob 17 is slid left and right along the central front fin 15b, the fin engaging portion 77 of the operation knob 17 pushes the vertical operation receiving portion 38 and directly rotates the central rear fin 12b to the center. Rotate left and right around the shaft 33b. In this state, the rear link 14 connects the first link shaft portion 34 (link shaft portions 34a, 34b, 34c) behind the first rotation shaft portion 33 (rotation shaft portions 33a, 33b, 33c). The rear fins 12a, 12b, and 12c of the first rear fin 12 rotate in conjunction with each other in parallel with each other, and the rear link 14 is rearward of the first rotation shaft portion 33 and the first link shaft portion 34, and is The second rear fin 13 (rear fins 13a, 13b) connected to the second link shaft portion 44 (link shaft portions 44a, 44b) ahead of the two rotation shaft portions 43 (rotation shaft portions 43a, 43b) 1 The rear fin 12 rotates in the opposite direction (reverse interlocking), and the wind direction is changed, that is, adjusted to the left and right.

  For example, when the operation knob 17 is operated from the neutral state shown in FIG. 6B to the left which is one side (in the vehicle width direction) (FIG. 6A), the first rear fin 12 The (rear fins 12a, 12b, 12c) move around the first rotation shaft portion 33 (the rotation shaft portions 33a, 33b, 33c) to the right, with the front side being the left side and the rear side being the other side. To turn. Therefore, the rear link to which the first link shaft portion 34 (link shaft portions 34a, 34b, 34c) located behind the first rotation shaft portion 33 (rotation shaft portions 33a, 33b, 33c) is coupled. 14 moves to the right, that is, in the direction opposite to the operation direction of the operation knob 17. Therefore, the second link shaft portion 44 (link shaft portions 44a and 44b) of the second rear fin 13 (rear fins 13a and 13b) loosely fitted to the second link bearing portion 54 (link bearing portions 54a and 54b) of the rear link 14. ) Slides rearward along the second link bearing portion 54 (link bearing portions 54a, 54b), and moves to the right, which is the moving direction of the rear link 14, so that the second rear fin 13 (The rear fins 13a and 13b) are centered on the second rotation shaft portion 43 (rotation shaft portions 43a and 43b) located behind the second link shaft portion 44 (link shaft portions 44a and 44b). It turns so that the right side and the rear side move to the left. That is, the first rear fin 12 and the second rear fin 13 rotate in directions opposite to each other.

  As a result, the first rear fin 12 (rear fins 12a, 12b, 12c) is inclined to the left, and the second rear fin 13 (rear fins 13a, 13b) is inclined to the right, so that the left rear rear fin of the left rear rear fin 13a of the second rear fin 13 is obtained. The rear side of the main body 42a approaches (contacts) one side plate portion 23, and the front side of the right rear rear fin main body 42b of the right rear rear fin 13b approaches (contacts) the other side plate portion 24. For this reason, in the ventilation path 26, the straight wind that flows along the position below the bearing portion 30 of the one side plate portion 23 is rectified to the center side (right side) in the left-right direction by the left rear rear fin 13a and is first. Directly blown to the left rear fin 12a of the rear fin 12, the left rear fin 12a rectifies leftward. At this time, the wind rectified by the left rear fin 12a is blown by the second rear fin 13 and bounces leftward from the left rear fin 12a because there is no louver on the left which is the direction of rectification by the left rear fin 12a. The wind bounces back to the right again and no turbulence is generated, and the air is reliably rectified to the left as it is. Further, the straight wind flowing along the other side plate portion 24 is blocked by the right rear rear fin 13b. Further, the wind flowing in other positions of the ventilation path 26 is rectified toward the left by the rear fins 12a, 12b, and 12c of the first rear fin 12. Therefore, the entire wind passing through the ventilation path 26 is reliably rectified leftward without going straight forward from the outlet 27 or flowing rightward.

  On the other hand, when the operation knob 17 is operated from the neutral state shown in FIG. 6B to the right side (the vehicle width direction outside) which is the other side (FIG. 6C), the first rear fin 12 The (rear fins 12a, 12b, 12c) rotate about the first rotation shaft portion 33 (rotation shaft portions 33a, 33b, 33c) so that the front side moves to the right and the rear side moves to the left. Therefore, the rear link to which the first link shaft portion 34 (link shaft portions 34a, 34b, 34c) located behind the first rotation shaft portion 33 (rotation shaft portions 33a, 33b, 33c) is coupled. 14 moves relatively to the left, that is, in the direction opposite to the operation direction of the operation knob 17. Therefore, the second link shaft portion 44 (link shaft portions 44a and 44b) of the second rear fin 13 (rear fins 13a and 13b) loosely fitted to the second link bearing portion 54 (link bearing portions 54a and 54b) of the rear link 14. ) Slides rearward along the second link bearing portion 54 (link bearing portions 54a and 54b), and moves to the left, which is the moving direction of the rear link 14, so that the second rear fin 13 (The rear fins 13a and 13b) are centered on the second rotation shaft portion 43 (rotation shaft portions 43a and 43b) located behind the second link shaft portion 44 (link shaft portions 44a and 44b). It turns so that the left side and the rear side move to the right. That is, the first rear fin 12 and the second rear fin 13 rotate in directions opposite to each other.

  As a result, the first rear fin 12 (rear fins 12a, 12b, 12c) tilts to the right, and the second rear fin 13 (rear fins 13a, 13b) tilts to the left, so that the left rear rear fin of the left rear rear fin 13a of the second rear fin 13 The front side of the main body 42a approaches (contacts) one side plate portion 23, and the rear side of the right rear rear fin main body 42b of the right rear rear fin 13b approaches (contacts) the other side plate portion 24. For this reason, in the ventilation path 26, the straight wind that flows along the position below the bearing portion 30 of the one side plate portion 23 is blocked by the left rear rear fin 13a. Further, the straight wind that flows along the other side plate portion 24 is rectified by the right rear rear fin 13b to the center side (left side) in the left-right direction and directly blown to the right rear fin 12c of the first rear fin 12, and this right rear fin. Rectified to the right by 12c. At this time, the wind rectified by the right rear fin 12c bounces from the right rear fin 12c to the right because it is blown by the right rear fin 13b because there is no louver on the right, which is the direction of rectification by the right rear fin 12c. The wind bounces back to the left again and no turbulence is generated, and it is reliably rectified to the right as it is. Further, the wind flowing in other positions of the ventilation path 26 is rectified rightward by the rear fins 12a, 12b, and 12c of the first rear fin 12. Therefore, the entire wind passing through the ventilation path 26 is reliably rectified rightward without going straight forward from the outlet 27 or flowing leftward.

  Therefore, according to the present embodiment, the first rear fin 12 and the second rear fin 13 can be connected by a single rear link 14 without using a plurality of gears as in the first embodiment. Since they can be interlocked and rotated in opposite directions, good air distribution performance can be obtained without increasing the number of parts more than necessary.

  Further, the second rotation shaft portion 43 (rotation shaft portions 43a and 43b) of the second rear fin 13 (rear fins 13a and 13b) is made to rotate more than the first rotation shaft portion 33 of the first rear fin 12. The front side portion, which is the end portion of the second rear fin 13 on the leeward side of the ventilation path 26, is located near the side plate portions 23, 24 of the case body 11 located in the left-right direction intersecting the shaft portion 33. By rotating in the direction close to 24, the ventilation path 26 between the side plate portions 23 and 24 is closed, so that the straight air flowing along the side plate portions 23 and 24 is caused to flow straightly through the second rear fin 13 (rear fin 13a). , 13b), and the straight wind does not go straight and blow through, and the air distribution performance can be further improved.

  In the second embodiment, the bent portions 52 of the rear link 14 of the first embodiment are provided at both ends of the rear link main body 51, and the bent portions 52 are provided at the positions of the bent portions 52. The second link shaft portion 44 of the second rear fin 13 may be connected by the two-link bearing portion 54.

  Next, a third embodiment will be described with reference to FIG. In addition, about the structure and effect | action similar to said each embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted. Further, in order to clarify the explanation, the front fins 15 and the front links 16 are omitted in FIG.

  In the wind direction adjusting apparatus 10 of the present embodiment, three first rear fins 12 and three second rear fins 13 are set.

  Of the second rear fins 13, the left side closer to one side plate part 23 is the left rear rear fin 13c, the center is the center rear rear fin 13d, the other side plate part 24 is closer to the right side, and the right rear rear fin 13e. That is, the left rear rear fin 13c constitutes a left rear rear fin main body 42c constituting the second rear fin main body 42, a left rear rotary shaft 43c constituting the second rotary shaft 43, and a second link shaft 44. Left rear link shaft portion 44c, and a central rear rear fin 13d includes a central rear rear fin body 42d constituting the second rear fin body 42, and a central rear rotation shaft portion 43d constituting the second rotation shaft portion 43. A central rear link shaft portion 44d constituting the second link shaft portion 44, and a right rear rear fin 13e constituting a right rear rear fin body 42e constituting the second rear fin body 42 and a second rotating shaft portion 43. And a right rear link shaft portion 44e constituting the second link shaft portion 44.

  Further, the left rear fin 12a has a left rotation shaft portion 33a in front of the left rear rear fin 13c constituting the second rear fin 13 and at a position closer to one side plate portion 23 (leftward) in the ventilation path 26. Is arranged. That is, the left rear fin 12a is arranged at a position closer to one side plate portion 23 than the left rear rear fin 13c constituting the second rear fin 13.

  Further, the right rear fin 12c has a right turning shaft portion 33c in front of the right rear rear fin 13e constituting the second rear fin 13 and at a position closer to the other side plate portion 24 (rightward). Is arranged. That is, the right rear fin 12c is arranged at a position closer to the other side plate portion 24 than the right rear rear fin 13e constituting the second rear fin 13.

  Further, the rear fins 12a, 12b, and 12c of the first rear fin 12 are separated from each other in the left-right direction by a distance that is wider than the distance between the rear fins 13c, 13d, and 13e of the second rear fin 13 in a front view. Has been.

  The rear link 14 has a first link bearing portion 53 (link bearing portions 53a, 53b, 53c) formed in a long hole shape having a longitudinal direction along the front-rear direction. Further, three second link bearing portions 54 are set in the rear link 14 corresponding to the second rear fin 13. That is, the second link bearing portion 54 includes a left rear link bearing portion 54c that receives the left rear link shaft portion 44c of the left rear rear fin 13c, and a central rear link bearing portion 54d that receives the central rear link shaft portion 44d of the central rear rear fin 13d. And a right rear link bearing portion 54e that receives the right rear link shaft portion 44e of the right rear rear fin 13e.

  Then, when the operation knob 17 is slid left and right along the central front fin 15b, the fin engaging portion 77 of the operation knob 17 pushes the vertical operation receiving portion 38 and directly rotates the central rear fin 12b to the center. Rotate left and right around the shaft 33b. In this state, the rear link 14 connects the first link shaft portion 34 (link shaft portions 34a, 34b, 34c) behind the first rotation shaft portion 33 (rotation shaft portions 33a, 33b, 33c). The rear fins 12a, 12b, and 12c of the first rear fin 12 rotate in conjunction with each other in parallel with each other, and the rear link 14 is rearward of the first rotation shaft portion 33 and the first link shaft portion 34, and is 2 The second rear fin 13 (rear fins 13c, 13d) connected to the second link shaft portion 44 (link shaft portions 44c, 44d, 44e) ahead of the rotation shaft portion 43 (rotation shaft portions 43c, 43d, 43e). , 13e) rotate in the opposite direction to the first rear fin 12 (reverse interlock), and the wind direction is changed, that is, adjusted to the left and right.

  For example, when the operation knob 17 is operated from the neutral state shown in FIG. 7B to the left which is one side (in the vehicle width direction) (FIG. 7A), the first rear fin 12 The (rear fins 12a, 12b, 12c) move around the first rotation shaft portion 33 (the rotation shaft portions 33a, 33b, 33c) to the right, with the front side being the left side and the rear side being the other side. To turn. Therefore, the first link shaft portion 34 (link shaft portions 34a, 34b, 34c) positioned rearward of the first rotation shaft portion 33 (rotation shaft portions 33a, 33b, 33c) is the first link bearing portion 53. The rear link 14 moves relatively to the right, that is, in the direction opposite to the operation direction of the operation knob 17, while sliding forward along the (link bearing portions 53a, 53b, 53c). Therefore, the second link shaft portion 44 (link shaft) of the second rear fin 13 (rear fins 13c, 13d, 13e) fitted to the second link bearing portion 54 (link bearing portions 54c, 54d, 54e) of the rear link 14 is provided. When the portions 44c, 44d, 44e) move together with the rear link 14 to the right, which is the direction of movement of the rear link 14, the second rear fin 13 (rear fins 13c, 13d, 13e) is moved to the second link shaft portion 44. Centered on the second rotation shaft 43 (rotation shaft 43c, 43d, 43e) located behind the (link shaft 44c, 44d, 44e), the front side moves to the right and the rear side moves to the left Rotate to That is, the first rear fin 12 and the second rear fin 13 rotate in directions opposite to each other.

  As a result, the first rear fin 12 (rear fins 12a, 12b, 12c) is tilted to the left, and the second rear fin 13 (rear fins 13c, 13d, 13e) is tilted to the right, whereby the left rear fin of the left rear fin 12a of the first rear fin 12 is The front side of the main body 32a approaches (contacts) one side plate portion 23, and the rear side of the right rear fin main body 32c of the right rear fin 12c approaches (contacts) the other side plate portion 24. For this reason, in the ventilation path 26, the straight wind that flows along the position below the bearing portion 30 of the one side plate portion 23 is blocked by the left rear fin 12a. The wind flowing in other positions of the ventilation path 26 is rectified rightward by the second rear fin 13 (rear fins 13c, 13d, 13e) and directly blown to the rear fins 12b, 12c of the first rear fin 12, and these rear fins Rectified to the left by 12b and 12c. Therefore, the entire wind passing through the ventilation path 26 is reliably rectified leftward without going straight forward from the outlet 27 or flowing rightward.

  On the other hand, when the operation knob 17 is operated from the neutral state shown in FIG. 7B to the right side (the vehicle width direction outer side) which is the other side (FIG. 7C), the first rear fin 12 The (rear fins 12a, 12b, 12c) rotate about the first rotation shaft portion 33 (rotation shaft portions 33a, 33b, 33c) so that the front side moves to the right and the rear side moves to the left. Therefore, the first link shaft portion 34 (link shaft portions 34a, 34b, 34c) positioned rearward of the first rotation shaft portion 33 (rotation shaft portions 33a, 33b, 33c) is the first link bearing portion 53. The rear link 14 moves relatively to the left, that is, in the direction opposite to the operation direction of the operation knob 17, while sliding forward along the (link bearing portions 53a, 53b, 53c). Therefore, the second link shaft portion 44 (link shaft) of the second rear fin 13 (rear fins 13c, 13d, 13e) fitted to the second link bearing portion 54 (link bearing portions 54c, 54d, 54e) of the rear link 14 is provided. When the parts 44c, 44d, 44e) move together with the rear link 14 to the left, which is the direction of movement of the rear link 14, the second rear fin 13 (rear fins 13c, 13d, 13e) becomes the second link shaft part 44. Centered on the second rotation shaft 43 (rotation shaft 43c, 43d, 43e) located behind the (link shaft 44c, 44d, 44e), the front side moves to the left and the rear side moves to the right Rotate to That is, the first rear fin 12 and the second rear fin 13 rotate in directions opposite to each other.

  As a result, the first rear fin 12 (rear fins 12a, 12b, 12c) tilts to the right, and the second rear fin 13 (rear fins 13c, 13d, 13e) tilts to the left, so that the left rear fin 12a of the left rear fin 12a of the first rear fin 12 The rear side of the main body 32a approaches (contacts) one side plate portion 23, and the front side of the right rear fin main body 32c of the right rear fin 12c approaches (contacts) the other side plate portion 24. For this reason, in the ventilation path 26, the straight wind flowing along the other side plate portion 24 is blocked by the right rear fin 12c. Further, the wind flowing in other positions of the ventilation path 26 is rectified to the left by the second rear fin 13 (rear fins 13c, 13d, 13e) and directly blown to the rear fins 12a, 12b of the first rear fin 12, and these rear fins. Rectified to the right by 12a and 12b. Therefore, the entire wind passing through the ventilation path 26 is reliably rectified rightward without going straight forward from the outlet 27 or flowing leftward.

  Therefore, according to the present embodiment, the first rear fin 12 and the second rear fin 13 are reversed from each other only by a single rear link 14 without using a plurality of gears and the like, as in the above embodiments. Since it can be interlocked and rotated in the direction, good air distribution performance can be obtained without increasing the number of parts more than necessary.

  Further, the first rotation shaft portion 33 (rotation shaft portions 33a, 33c) of the first rear fin 12 (rear fins 12a, 12c) is rotated by the second rotation shaft portion 43 of the second rear fin 13 more than the second rotation shaft portion 43. The front side portion, which is the end portion on the leeward side of the ventilation path 26 of the first rear fin 12, is located near the side plate portions 23, 24 of the case body 11 located in the left-right direction intersecting the shaft portion 43. By rotating in the direction close to 24, the ventilation path 26 between the side plate portions 23, 24 is closed, thereby allowing the straight wind flowing along the side plate portions 23, 24 to flow straightly through the first rear fin 12 (rear fin 12a , 12c), and the straight wind does not go straight and blow through, and the air distribution performance can be further improved.

  In the second and third embodiments described above, the rear link main body 51 of the rear link 14 is formed into an elongated rod shape as in the fourth embodiment shown in FIG. In addition, a long-hole-shaped second link bearing portion 54 having a longitudinal direction along the front-rear direction is provided, and the fins 12, 13 are disposed between the long-hole-shaped second link bearing portion 54 and the rear link body 51. You may provide the thin part 79 used as the hinge part which deform | transforms at the time of rotation and acts as what is called a joint.

  In each of the above embodiments, the rear fins 12 and 13 are configured to rotate left and right and the front fins 15 are configured to rotate up and down. For example, the rear fins 12 and 13 are configured to rotate up and down, and the front fins 15 It is good also as a structure which rotates right and left.

  Further, although the operation knob 17 is connected to the first rear fin 12 via the front fin 15, it may be connected to the second rear fin 13, for example.

  Further, the front fin 15 is not an essential configuration. When the front fin 15 is not provided, the operation knob 17 may be directly connected to either the first rear fin 12 (center rear fin 12b) or the second rear fin 13.

  Further, the number of the rear fins 12 and 13 can be appropriately set in accordance with the size of the wind direction adjusting device 10 and the like.

  The second rear fin 13 may be configured not only to be positioned at the rear of at least one side of the first rear fin 12 but also to be positioned to the rear of the first rear fin 12.
