Description

  The present invention relates to an air-conditioning register that changes the direction of air-conditioning air sent from an air-conditioning apparatus and blown into a room.

  An air conditioning register for changing the direction of air conditioning air sent from the air conditioner and blown into the passenger compartment is incorporated in the instrument panel of the vehicle. As one form of this air-conditioning register, various types have been conventionally considered in which the dimension is greatly different between the vertical direction and the horizontal direction, for example, a thin air-conditioning register in which the horizontal dimension is larger than the vertical dimension. For example, a thin air-conditioning register described in Patent Document 1 includes a case, a pair of auxiliary fins, a main fin, and an interlocking mechanism.

  The case has a rectangular tube shape with a low height, and has an internal space as a ventilation path for air for air conditioning. The pair of auxiliary fins extend in the vehicle width direction at locations close to the upper and lower wall portions of the case. Both auxiliary fins are supported to be tiltable in the vertical direction with respect to the left and right wall portions of the case. The main fin extends in the vehicle width direction between the auxiliary fins, and is supported so as to be tiltable in the vertical direction with respect to the left and right wall portions of the case.

  The interlocking mechanism makes both auxiliary fins parallel to the upper and lower wall portions when the main fin is parallel to the upper and lower wall portions. In addition, when the main fin is tilted from the above state, the interlocking mechanism has upper and lower wall portions so that both of the auxiliary fins are pushed toward the inside of the ventilation path with the tilt. Tilt against.

  Therefore, when the main fin is tilted from a state parallel to the upper and lower wall portions, the air-conditioning air flowing through the intermediate portion in the vertical direction can be changed in direction by flowing along the main fin. Air-conditioning air that flows near the upper wall of the ventilation path flows along the upper auxiliary fin, and air-conditioning air that flows near the lower wall of the ventilation path flows along the lower auxiliary fin. The direction can be changed to the inside of the air passage. These air-conditioning airs are collected around the main fin, and can be turned by flowing along the main fin. As a result, the air for air conditioning is blown from the case in the direction toward the main fin, and the directivity of the air for air conditioning when the main fin is inclined is improved.

JP 2010-105507 A

  By the way, in the air-conditioning register described in Patent Document 1 above, the upper and lower auxiliary fins are tilted in conjunction with the main fin, and the downstream end is inclined with respect to the upper and lower walls so as to protrude toward the inside of the ventilation path. When further thinning is attempted, the inclined main fin and the auxiliary fin near the upstream end of the main fin may interfere with each other. Therefore, there is a problem that there is a limit in reducing the thickness.

  The present invention has been made in view of such circumstances, and the object thereof is for air conditioning that can suppress interference with the auxiliary fin when the main fin is inclined and can be further reduced in thickness. To provide a register.

  In order to achieve the above object, the invention according to claim 1 is a pair of first wall portions facing each other in the first direction and a pair of first wall portions facing each other in a second direction orthogonal to the first direction. The two wall portions are formed in a cylindrical shape longer in the first direction than the second direction, and have a case having an internal space as a ventilation path for air for air conditioning, and approach the second wall section in the ventilation path The pair of auxiliary fins that extend in the first direction at the locations and are supported by the support shaft so as to be tiltable in the second direction with respect to the first wall portion, and in the first direction between the two auxiliary fins A main fin that is extended and supported by the support shaft so as to be tiltable in the second direction with respect to the first wall portion, and is supported by the case so as to be displaceable, and an engaging portion for each auxiliary fin is engaged. A pair of engaged portions, and each engaged portion compensates for the displacement. A transmission member configured by a transmission region transmitting to the fin and a non-transmission region not transmitting; and a gear mechanism provided between the main fin and the transmission member and transmitting the tilt of the main fin to the transmission member. When the main fin is in a state parallel to the second wall portion, the respective engaging fins are positioned at the boundary between the transmission region and the non-transmission region, so that both auxiliary fins are When the main fin is tilted from the state, the engaging portion of the auxiliary fin on the side close to the upstream end of the main fin is positioned in the non-transmission region. The auxiliary fin is in a state parallel to the second wall portion, and the engaging portion of the auxiliary fin on the far side is positioned in the transmission region, so that the auxiliary fin is Upstream end is summarized in that tilting relative to the second wall portion, as pushed out toward the inside of the ventilation passage.

  According to said structure, when a main fin is made into the state parallel to the 2nd wall part, the engaging part for every auxiliary | assistant fin becomes the boundary of the transmission area | region and non-transmission area | region in the to-be-engaged part of a transmission member. It is located and it is made into the state parallel to the 2nd wall part in the location where the auxiliary fin approached the 2nd wall part.

  When the main fin is tilted in the second direction about the support shaft from the above state, the tilt is transmitted to the transmission member through the gear mechanism, and the transmission member is displaced. The pair of engaged portions provided on the transmission member are also displaced. At this time, the engaging portion of the auxiliary fin on the side close to the upstream end of the main fin is located in the non-transmitting region, and the displacement of the transmitting member is not transmitted to the engaging portion and the auxiliary fin. Therefore, the auxiliary fin is maintained in a state parallel to the second wall portion.

  The engaging portion of the auxiliary fin on the side far from the upstream end of the main fin is located in the transmission region, and the displacement of the transmitting member is transmitted to the engaging portion and the auxiliary fin. Therefore, the auxiliary fin is tilted with the support shaft as a fulcrum, and the downstream end of the auxiliary fin is inclined with respect to the second wall portion so as to protrude toward the inside of the ventilation path.

  Therefore, in the ventilation path of the case, the air-conditioning air flowing through the intermediate portion in the second direction can be changed in direction by flowing along the main fin. Further, the air-conditioning air that flows in the vicinity of the second wall portion on the side far from the upstream end of the main fin changes its direction to the inside of the air passage by flowing along the auxiliary fin on the side far from the upstream end. The air for air conditioning is collected around the main fin, and the direction is changed by flowing along the main fin. Accordingly, the air-conditioning air is blown out from the case in the direction toward the main fin, and the directivity of the air-conditioning air is improved.

  Further, as described above, when the main fin is tilted, the auxiliary fin on the side close to the upstream end of the main fin does not tilt and maintains a state parallel to the second wall portion. Therefore, even if the upstream end of the main fin is brought close to the auxiliary fin on the side close to the upstream end, interference between the two is less likely to occur. Therefore, by arranging the auxiliary fin and the second wall near the upstream end of the main fin at a location close to the main fin, it is possible to reduce the size of the air conditioning register in the second direction.

  The invention according to claim 2 is the invention according to claim 1, wherein an arm extends from the support shaft for each auxiliary fin in a direction perpendicular to the support shaft, and the support shaft of the arm. The gist of the present invention is that a transmission shaft is provided as the engaging portion at a position deviated from the above.

  According to said structure, in the arm extended from the spindle for every auxiliary fin, the transmission shaft provided in the location biased from the spindle functions as an engaging part for every auxiliary fin. Therefore, when the transmission member is displaced with the tilting of the main fin and the pair of engaged portions are displaced, the position of the transmission shaft in the engaged portion is changed. When the transmission shaft is positioned in the transmission region of the engaged portion, the displacement of the transmission member is transmitted to the transmission shaft through the engaged portion. By this transmission, the arm is tilted in the second direction with the auxiliary shaft as a fulcrum with the auxiliary fin. Further, when the transmission shaft is located in the non-transmission region of the engaged portion, the displacement of the transmission member is not transmitted to the transmission shaft through the engaged portion, and therefore the arm and the auxiliary fin do not tilt with the support shaft as a fulcrum.

  The invention according to claim 3 is the invention according to claim 1 or 2, wherein the transmission member is supported to be tiltable in the second direction by an axis with respect to the first wall portion, and the engaged member The gist of the present invention is that the joint portion is constituted by a cam member provided with a cam hole or a cam groove.

  According to the above configuration, the cam member supported by the shaft with respect to the first wall portion functions as a transmission member, and the pair of cam holes or the pair of cam grooves provided in the cam member functions as the engaged portion. To do. Therefore, when the main fin is tilted in the second direction about the support shaft, the tilt is transmitted to the cam member through the gear mechanism. The cam member tilts in the same direction with the shaft as a fulcrum, and a pair of cam holes or a pair of cam grooves rotate around the shaft. The position of the engaging portion for each auxiliary fin in the cam hole or cam groove changes. When the engaging portion is located in the transmission region of the cam hole or cam groove, the tilt of the cam member is transmitted to the engaging portion. The engaging portion moves, and the auxiliary fin tilts with the support shaft as a fulcrum. When the engaging part is located in the non-transmitting region, the tilting of the cam member is not transmitted to the engaging part. The engaging portion does not move, and the auxiliary fin does not tilt.

  According to a fourth aspect of the present invention, in the third aspect of the present invention, the gear mechanism includes a drive gear provided on the support shaft of the main fin so as to be integrally rotatable, and the cam member. The gist is provided with a driven gear that is movably provided and meshed with the drive gear.

  According to the above configuration, when the main fin is tilted in the second direction with the support shaft as a fulcrum, the drive gear on the support shaft also rotates integrally with the main fin about the support shaft. As a result of this rotation, the meshing position of the driven gear with the drive gear changes, and the driven gear is integrated with the cam member and rotates about the shaft.

  According to the air-conditioning register of the present invention, it is possible to suppress the interference with the auxiliary fin when the main fin is inclined, and to further reduce the thickness.

The transmission shafts 63 and 65 are engaged with the cam holes 68 and 69 so as to satisfy the following conditions.

  (I) In a state where the main fin 31 is parallel to the second wall portion 22, the transmission shaft 63 is a boundary portion between the first hole portion 68A (non-transmission region) and the second hole portion 68B (transmission region). The transmission shaft 65 is located at a boundary portion between the first hole 69A (non-transmission region) and the second hole 69B (transmission region). That is, the transmission shaft 63 is positioned closer to the central portion between the second wall portions 22 than the support shaft 34 of the auxiliary fin 33 (directly above the shaft 28), and the transmission shaft 65 is connected to the auxiliary fin 35. It is located at a location closer to the central portion than the support shaft 36 (directly below the shaft 28).

In this state, the auxiliary fins 33 and 35 are parallel to the second wall portion 22.
(Ii) As shown in FIG. 12, in a state where the main fin 31 is inclined with respect to the second wall portion 22 so as to become lower toward the downstream side, the transmission shaft 63 is positioned in the first hole 68A, and the transmission shaft 65 Is located in the second hole 69B.

  In this state, the upper auxiliary fin 33, which is an auxiliary fin closer to the upstream end of the main fin 31, is in a state parallel to the second wall portion 22. Further, the lower auxiliary fin 35, which is the auxiliary fin far from the upstream end of the main fin 31, is inclined with respect to the second wall portion 22 so as to be higher toward the downstream side, and the downstream end is the ventilation path. 20 to the inside.

  (Iii) Although not shown, contrary to the above (ii), in a state where the main fin 31 is inclined with respect to the second wall portion 22 so as to become higher toward the downstream side, the transmission shaft 63 is formed in the second hole portion 68B. The transmission shaft 65 is located in the first hole 69A.

  In this state, the upper auxiliary fin 33 that is the auxiliary fin farther from the upstream end of the main fin 31 is inclined with respect to the second wall portion 22 so as to become lower toward the downstream side, and the downstream end is ventilated. It rushes to the inside of the road 20. The lower auxiliary fin 35, which is an auxiliary fin closer to the upstream end of the main fin 31, is in a state parallel to the second wall portion 22.

  Further, as shown in FIG. 11, in the state where the main fin 31 is inclined at the maximum angle that can be taken, the auxiliary fins 35 and 33 on the side farther from the upstream end of the main fin 31 are inclined toward the main fin 31. Be made. In the present embodiment, the auxiliary fins 35 and 33 are set so as to be inclined toward the central portion of the main fin 31 with respect to the flow direction of the air-conditioning air A in the ventilation path 20.

  In addition, in a state where the main fin 31 is inclined at the maximum angle that can be taken, a part of the operation knob 40 on the downstream side is located downstream of the auxiliary fins 35 and 33 on the side far from the upstream end of the main fin 31. It is set to be located. In other words, when the air conditioning register is viewed from the downstream side to the upstream side, a part of the operation knob 40 on the downstream side and the downstream ends of the auxiliary fins 35 and 33 on the side far from the upstream end of the main fin 31 are shown. Are overlapping. In addition, the code | symbol O in FIG. 11 has shown the overlapping part of the operation knob 40 and the auxiliary fins 35 and 33. FIG.

<Shut damper 70>
As shown in FIGS. 5 and 7, the shut damper 70 opens and closes the ventilation path 20 on the upstream side of the upstream fin group in the case 10. The shut damper 70 corresponds to a surface orthogonal to the ventilation path 20, and has a main body 71 that has a rectangular plate shape elongated in the first direction (vehicle width direction) rather than the second direction (vertical direction), and the main body 71 And a seal portion 72 attached to the periphery of the.

  From both end faces of the main body 71 in the first direction (vehicle width direction), the support shaft 73 protrudes outward in the same direction. Both the support shafts 73 are located in the center between the second wall portions 22 in the second direction (vertical direction). The positions of both the support shafts 73 are the same as the positions in the second direction (vertical direction) of the both support shafts 32 of the main fin 31 described above. The shut damper 70 is supported on the first wall portion 21 by the bearing portion 29 on both the support shafts 73, and can be tilted in the second direction (vertical direction) between the open position and the closed position. In the open position, the shut damper 70 is in a state parallel to the second wall portion 22 at the central portion between both the second wall portions 22, and greatly opens the ventilation path 20 (see the solid line in FIG. 5). . In the closed position, the shut damper 70 is inclined with respect to the second wall portions 22, contacts the inner wall surfaces of the first wall portion 21 and the second wall portion 22 at the seal portion 72, and closes the ventilation path 20 ( (See the two-dot chain line in FIG. 5).

<Damper drive mechanism 80>
As shown in FIGS. 1, 8, and 10, the damper drive mechanism 80 is a mechanism for tilting the shut damper 70 to open and close the ventilation path 20, sandwiching the case 10, and in a first direction (vehicle width direction) ) Is provided on the side opposite to the interlocking mechanism 60. The damper drive mechanism 80 includes an operation dial 81 and a rotation transmission unit 82. The operation dial 81 is supported with respect to the case 10 so as to be rotatable in the second direction (vertical direction). A part of the operation dial 81 is exposed to the downstream side through the window portion 13 </ b> A of the bezel 13.

  The rotation transmitting portion 82 is for transmitting the rotation of the operation dial 81 to the shut damper 70, and is outward in the first direction (vehicle width direction) from the first wall portion 21. It is provided between the dial 81 and the support shaft 73 of the shut damper 70.

  The rotation transmission part 82 is comprised by the link mechanism, the gear mechanism, etc. In the present embodiment, a pin 83 protruding outward in the first direction (vehicle width direction) is provided on the operation dial 81. A lever 84 is provided on one support shaft 73 of the shut damper 70 so as to be integrally rotatable. A pin 85 protruding outward in the first direction (vehicle width direction) is provided at the tip of the lever 84. The pins 83 and 85 are connected by a long link member 86 extending in the ventilation direction.

  Further, in the present embodiment, as shown in FIGS. 5 and 6, each notch portion 55 is in the second direction (vertical direction) in the upstream side fins 50 and 51, out of both the second wall portions 22. The downstream end is provided at a portion nearer to the upstream side (upper second wall portion 22). In the present embodiment, each notch 55 is slightly separated in the second direction (vertical direction) from the central portion between the second wall portions 22 and from the central portion to the upper second wall portion 22 side. It is provided in the area between the places. Each notch 55 is formed larger than the size (thickness) in the same direction of the connecting rod 57 in the above direction, and enables the connecting rod 57 to intersect. In other words, each notch 55 is provided only at a location where the connecting rod 57 intersects and its surrounding location in the second direction (vertical direction).

  The notch 55 is provided in the upstream portion of each upstream fin 50, 51 with respect to the ventilation direction of the air-conditioning air A in the ventilation path 20. Each notch 55 extends from the upstream end face of each upstream fin 50, 51 toward the downstream side. Each notch 55 is formed larger than the size (width) in the same direction of the connecting rod 57 in the ventilation direction, and allows the connecting rods 57 to cross each other. In other words, each notch 55 is provided only at a location where the connecting rod 57 intersects and its peripheral location in the ventilation direction.

  The connecting shaft 56 for each of the upstream fins 50, 51 protrudes upward from a location away from the support shaft 52 toward the upstream side at the bottom of the notch 55. Then, the upstream fins 50 and 51 are connected to each other by the connecting rod 57 by engaging the connecting shaft 56 for each of the upstream fins 50 and 51 into a hole formed in the connecting rod 57.

  Here, as shown in FIG. 4, with respect to a plane P orthogonal to the flow direction of the air-conditioning air A at the air outlet 14, the projected surface of the main fin 31 and the shut damper 70 is a projection plane P1, and the connecting rod A projected surface 57 is defined as a projection plane P2. Then, when the main rod 31 and the shut damper 70 are both parallel to the second wall portion 22 by arranging the connecting rod 57 at the above-described location, the entire projection surface P2 of the connecting rod 57 is It is included in the projection plane P <b> 1 of the main fin 31 and the shut damper 70.

As described above, the air-conditioning register of this embodiment is configured. Next, the operation of this air conditioning register will be described.
The two-dot chain line in FIGS. 5 and 6 shows a state when the shut damper 70 is in the closed position. In this state, the ventilation path 20 is blocked by the shut damper 70. The flow of the air conditioning air A in the ventilation path 20 is blocked, and the blowing of the air conditioning air A from the air outlet 14 is stopped.

  On the other hand, the solid line in FIGS. 5 and 6 shows the state when the shut damper 70 is in the open position. In this state, the ventilation path 20 is fully opened, and the air-conditioning air A flows separately on the upper side and the lower side of the shut damper 70. The air-conditioning air A that has passed through the shut damper 70 flows along the upstream fin group and the downstream fin group, and then blows out from the air outlet 14.

  Switching of the shut damper 70 from the closed position to the open position, and switching from the open position to the closed position is performed through a turning operation of the operation dial 81. When the operation dial 81 is rotated by the occupant, the rotation is transmitted to the main body 71 via the pin 83, the link member 86, the pin 85, the lever 84 and the support shaft 73 as shown in FIG. The shut damper 70 is tilted.

In the following description, it is assumed that the shut damper 70 is in the open position. 9 and 12 do not show details.
5 to 7 show the air-conditioning register in which the main fins 31 are parallel to the second wall portion 22.

  In this air conditioning register, as shown in FIG. 9, the drive gear 61 meshes with the driven gear 66 at the teeth of the central portion in the second direction (vertical direction), and the cam member 67 is parallel to the second wall portion 22. It becomes a state. The transmission shaft 63 of the upper auxiliary fin 33 engages with the cam hole 68 at the boundary between the first hole 68A and the second hole 68B. The arm 62 is inclined so as to become lower toward the upstream side, and the upper auxiliary fin 33 is stored in the upper storage recess 24 in a state parallel to the second wall portion 22.

  Further, the transmission shaft 65 of the lower auxiliary fin 35 engages with the cam hole 69 at the boundary portion between the first hole 69A and the second hole 69B. The arm 64 is inclined so as to be higher toward the upstream side, and the auxiliary fin 35 is parallel to the second wall portion 22 and stored in the lower storage recess 24.

  Therefore, as shown by the two-dot chain arrows in FIGS. 5 and 6, the air-conditioning air A that has passed through the shut damper 70 receives almost no resistance from each auxiliary fin 33, 35, and the main fin 31, auxiliary fin It flows with little pressure loss along the 33 and 35 and the second wall portion 22.

  Here, in general, in the air-conditioning register, the components arranged in the case 10 can be a factor for reducing the actual opening area of the air outlet 14. The actual opening area is an area where the above-described components are not projected on the surface orthogonal to the ventilation direction of the air-conditioning air A at the air outlet 14. The connecting rod 57 that connects the plurality of upstream fins 50 and 51 can be one of the factors that reduce the actual opening area. As the actual opening area decreases, the ventilation resistance increases, pressure loss increases, and noise is generated. Therefore, in order to suppress such pressure loss and noise, it is important to reduce the projection surface of the parts in the case 10 including the connecting rod 57.

  In this regard, in the present embodiment, at least a part of the projection plane P2 of the connecting rod 57 is included in the projection plane P1 of the main fin 31 and the shut damper 70 (see FIG. 4). Therefore, the total area of the projection planes P1 and P2 of the main fin 31, the shut damper 70 and the connecting rod 57 is greater than the case where the projection plane P2 of the connecting rod 57 is not included in the projection plane P1 of the main fin 31 and the shut damper 70 at all. Becomes smaller. Accordingly, the decrease in the actual opening area due to the connecting rod 57 is reduced.

  In particular, in the present embodiment, in the second direction (vertical direction), the entire projection plane P2 of the connecting rod 57 is included in the projection plane P2 of the main fin 31 and the shut damper 70. Therefore, the total area of the projection surfaces P1 and P2 of the main fin 31, the shut damper 70, and the connecting rod 57 is substantially the smallest of the total areas that can be taken. The reduction in the actual opening area due to the connecting rod 57 is substantially minimized, and consequently the ventilation resistance is substantially minimized.

  As another means for reducing the projection plane of the components in the case 10, it is conceivable to arrange the connecting rod 57 outside the ventilation path 20 (case 10). However, in this case, there is a possibility that the overall dimensions of the air-conditioning register, in particular the vertical dimension, will increase by a considerable amount due to the connecting rod 57 and the like.

  In this regard, in the present embodiment, the connecting rod 57 disposed in the ventilation path 20 (case 10) is less likely to affect the overall size of the air conditioning register. Therefore, the overall size of the air conditioning register is smaller than when the connecting rod 57 is disposed outside the ventilation path 20 (case 10).

  By the way, when a downward force is applied to the operation knob 40 from the above state, the main fin 31 is tilted counterclockwise about the support shaft 32 as shown in FIGS. With this tilting, the drive gear 61 rotates in the same direction with the support shaft 32 as a fulcrum. The meshing position of the driven gear 66 with the drive gear 61 changes, and the driven gear 66 rotates with the cam member 67 in the clockwise direction. Along with this, both cam holes 68 and 69 also turn around the shaft 28 in the same direction, and the engagement positions of the transmission shafts 63 and 65 in the cam holes 68 and 69 change.

  The engagement position of the transmission shaft 63 at the cam hole 68 changes from the boundary portion between the first hole portion 68A and the second hole portion 68B to the side closer to the downstream end of the first hole portion 68A. Therefore, the tilt of the cam member 67 is not transmitted to the transmission shaft 63 through the cam hole 68, and the transmission shaft 63 does not move. The arm 62 maintains an inclined state that becomes lower toward the upstream side. As a result, the auxiliary fin 33 on the side close to the upstream end of the main fin 31 is maintained in a state parallel to the second wall portion 22.

Note that the transmission shaft 63 reaches the downstream end of the first hole 68A when the main fin 31 is inclined at the maximum angle downward.
In contrast, the engagement position of the transmission shaft 65 at the cam hole 69 changes from the boundary portion between the first hole portion 69A and the second hole portion 69B to the side closer to the upstream end of the second hole portion 69B. Therefore, the tilt of the cam member 67 is transmitted to the transmission shaft 65 through the cam hole 69. The transmission shaft 65 receives a downward force from the wall surface of the second hole 69B and moves downward, and the arm 64 is tilted clockwise with the support shaft 36 as a fulcrum. The lower auxiliary fin 35 connected to the arm 64 via the support shaft 36 is tilted in the same direction with the support shaft 36 as a fulcrum.

  When the main fin 31 is tilted downward by the maximum angle, the transmission shaft 65 reaches the upstream end of the second hole 69B. At this time, the arm 64 is in a state parallel to the second wall portion 22. As a result, as shown in FIG. 11, the auxiliary fins 35 on the side far from the upstream end of the main fin 31 are inclined toward the central portion in the main fin 31 with respect to the ventilation direction of the air-conditioning air A, and the downstream end Squeezes out to the inside of the ventilation path 20.

  Therefore, the air-conditioning air A that flows through the intermediate portion in the second direction (vertical direction) can be changed in direction by flowing along the main fin 31. In addition, the air-conditioning air A flowing along the lower second wall portion 22 is changed to the inner side of the ventilation path 20 by the lower auxiliary fins 35, and the second direction (vertical direction) of the ventilation path 20. Near the center of the main fin 31. The air-conditioning air A flows along the main fin 31 inclined so as to become lower toward the downstream side, and blows off obliquely downward from the outlet 14.

  At this time, the upstream end of the inclined main fin 31 is close to the upper auxiliary fin 33, and the gap between the two is slight. Therefore, there is little air-conditioning air A that flows straight through this gap.

  Further, even if the air-conditioning air A tries to flow between the main fin 31 and the lower auxiliary fin 35 in a state parallel to the second wall portion 22, the air-conditioning air A is downstream of the auxiliary fin 35. It hits the operation knob 40 located on the side. The air-conditioning air A flows along the operation knob 40 and flows in a direction (obliquely downward) toward the main fin 31.

  When returning the main fin 31 from the above state to a state parallel to the second wall portion 22, an upward force is applied to the operation knob 40. This force causes the main fin 31 to tilt clockwise with the drive shaft 61 and the support shaft 32 as a fulcrum. The meshing position of the driven gear 66 with the drive gear 61 changes, the cam member 67 tilts counterclockwise about the shaft 28, and both cam holes 68 and 69 pivot around the shaft 28 in the same direction.

  The engagement position of the transmission shaft 63 at the cam hole 68 changes from the downstream end of the first hole 68A toward the side closer to the boundary with the second hole 68B. Therefore, the tilt of the main fin 31 is not transmitted to the transmission shaft 63 through the cam hole 68. The transmission shaft 63 does not move, and the inclined state where the arm 62 becomes lower toward the upstream side is maintained. As a result, the auxiliary fin 33 continues to be stored in the upper storage recess 24 in a state parallel to the second wall portion 22.

  On the other hand, the engagement position of the transmission shaft 65 at the cam hole 69 changes from the upstream end of the second hole 69B toward the side closer to the boundary with the first hole 69A. Therefore, the tilt of the cam member 67 is transmitted to the transmission shaft 65 through the cam hole 69, and the arm 64 is tilted counterclockwise with the auxiliary fin 35 and the support shaft 36 as a fulcrum. When the transmission shaft 65 moves along the second hole 69B to the boundary with the first hole 69A, as shown in FIG. 9, the arm 64 is inclined so as to become higher toward the upstream side, and FIG. As shown in FIG. 6, the auxiliary fin 35 is stored in the lower storage recess 24 in a state parallel to the second wall portion 22.

  When an upward force is applied to the operation knob 40 on the main fin 31 that is parallel to the second wall portion 22, the main fin 31 and the auxiliary fins 33 and 35 are not described above. The reverse operation is performed. The details of this operation are not described here.

  Here, when the main fin 31 is tilted in the second direction (vertical direction) with the support shaft 32 as a fulcrum from a state parallel to the second wall portion 22, the cam member 67 supports the shaft 28 with the tilt. Tilt as. At this time, in order to maintain the auxiliary fins 33 and 35 close to the upstream end of the main fin 31 in a state parallel to the second wall portion 22, the cam holes 67 and 69 are tilted by the cam member 67. The first holes 68A and 69A are set as non-transmission areas that do not transmit to the transmission shafts 63 and 65. The first holes 68A and 69A are displaced near the transmission shafts 63 and 65 of the auxiliary fins 33 and 35 as the cam member 67 tilts.

  At this time, depending on the position of the transmission shafts 63 and 65 in the second direction (vertical direction), the peripheral portions of the first hole portions 68A and 69A in the cam member 67 may extend from between the second wall portions 22 in the second direction (vertical direction). Direction) and may interfere with parts around the case 10.

  In this regard, in this embodiment, as shown in FIG. 9, when the main fin 31 is in a state parallel to the second wall portion 22, the transmission shafts 63 and 65 are supported by the support shafts 34 of the auxiliary fins 33 and 35. , 36 is located at a location closer to the central portion (shaft 28) between the second wall portions 22. Therefore, the first hole portions 68A and 69A are located near the transmission shafts 63 and 65, that is, between the two wall portions 22 rather than the support shafts 34 and 36 of the auxiliary fins 33 and 35 as the cam member 67 tilts. It will be displaced in the vicinity of the location close to the central portion (axis 28). As a result, as shown in FIG. 12, when the main fin 31 is inclined at the maximum possible angle with respect to the second wall portion 22, the peripheral portions of the first hole portions 68A and 69A in the cam member 67 are It protrudes outward in the second direction (vertical direction) from between the second wall portions 22 and hardly interferes with components around the case 10.

  As shown in FIG. 7, when a force in the first direction (vehicle width direction) is applied to the operation knob 40 (when the operation knob 40 is operated in the same direction), the operation knob 40 is moved to the main fin 31. Slide up. The force applied to the operation knob 40 is transmitted to the transmission portion 54 of the central upstream fin 50 via the fork portion 41. The upstream fin 50 is tilted to the side in which the operation knob 40 is operated in the first direction (vehicle width direction) with the support shaft 52 as a fulcrum. The movement of the upstream fin 50 with the support shaft 52 as a fulcrum is transmitted to the other upstream fins 51 via the connection shaft 56 and the connection rod 57. By this transmission, all the upstream fins 51 are tilted to the operated side of the operation knob 40 in synchronization with the upstream fins 50. When the air-conditioning air A passes through the upstream fins 50 and 51 and flows along the upstream fins 50 and 51 tilted as described above, the air is changed in the first direction (vehicle width direction). And blow out from the outlet 14.

  By the way, as shown in FIG.7 and FIG.8, in the ventilation path 20, the area | region from the downstream end of the upstream fins 50 and 51 to the blower outlet 14 is air-conditioning air A after passing the upstream fins 50 and 51. The directivity of can be reduced. The degree of this decrease increases as the region becomes longer in the ventilation direction (as the distances D1 and D2 from the downstream ends of the upstream fins 50 and 51 to the outlet 14 become longer). In this embodiment, since the blower outlet 14 inclines with respect to both the 2nd wall parts 22, said distance D1, D2 is what has a downstream end located in the more downstream side among both the 2nd wall parts 22 (lower side) The closer to the second wall portion 22) on the side, the longer. Therefore, the closer to the lower second wall portion 22, the longer the distances D <b> 1 and D <b> 2 from the downstream ends of the upstream fins 50 and 51 to the outlet 14 and the greater the degree of directivity reduction.

  On the other hand, the ability of the upstream fins 50 and 51 to change the direction of the flow of the air conditioning air A, that is, the performance of improving the directivity is the length L1 and L2 of the upstream fins 50 and 51 with respect to the ventilation direction of the air conditioning air A. The longer it is, the higher it becomes. When the cutout portion 55 for arranging the connecting rod 57 is provided, the lengths L1 and L2 of the upstream fins 50 and 51 are correspondingly shortened, and the flow direction is more than the portion without the cutout portion 55. The performance of changing (increasing directivity) is reduced.

In this regard, in the present embodiment, in the upstream fins 50 and 51, the notch portion 55 is provided at a site on the side closer to the upper second wall portion 22 where the downstream end is located on the upstream side.
Therefore, as shown in FIG. 8, at a location close to the lower second wall portion 22, the distance D <b> 1 from the downstream end of the upstream fins 50, 51 to the outlet 14 is long, and the degree of directivity is reduced. large. However, in the upstream fins 50 and 51, the notch portion 55 is not provided in the upstream portion of the above location. The length L1 of the upstream fins 50, 51 is longer by the amount of the notch 55, and the performance of changing the flow direction (increasing directivity) is high. Therefore, the air-conditioning air A whose directivity is enhanced by the portion where the notch 55 is not provided in the upstream fins 50 and 51 passes through the region where the degree of directivity is greatly reduced. As a result, the air-conditioning air A is blown out from the air outlet 14 with appropriate directivity in the first direction (vehicle width direction).

  On the other hand, as shown in FIG. 7, the distance D2 from the downstream end of the upstream fins 50, 51 to the outlet 14 is located at a location close to the upper second wall portion 22 where the downstream end is located on the upstream side. It is short and the degree of directivity degradation is small. In the upstream fins 50 and 51, a notch portion 55 is provided at a portion on the upstream side of the above-described portion. The length L2 of the upstream fins 50, 51 is short by the notch 55, and the performance of changing the flow direction (increasing directivity) in the first direction (vehicle width direction) is low. Therefore, the air-conditioning air A whose directivity is reduced by the portion of the upstream fins 50 and 51 whose length is shortened by the notch 55 passes through the region where the degree of directivity is small. As a result, the air-conditioning air A is blown out from the air outlet 14 with appropriate directivity in the first direction (vehicle width direction).

  In this way, the distances D1 and D2 from the downstream ends of the upstream fins 50 and 51 to the outlet 14 and the lengths L1 and L2 of the upstream fins 50 and 51 in the ventilation direction are considered, and the notch Since the position 55 is set, variation in directivity in the second direction (vertical direction) is reduced.

According to the embodiment described in detail above, the following effects can be obtained.
(1) The auxiliary fins 33 and 35 are supported by the first wall portion 21 at a location approaching the second wall portion 22 of the ventilation passage 20, and the main fin 31 is placed between the auxiliary fins 33 and 35 on the first wall portion 21. Support (FIG. 5). A cam member 67 provided with a pair of cam holes 68 and 69 including first holes 68A and 69A and second holes 68B and 69B is supported by the case 10. The tilt of the main fin 31 is transmitted to the cam member 67 through the gear mechanism 59 (FIG. 9).

  When the main fin 31 is made parallel to the second wall portion 22, the interlocking mechanism 60 causes the transmission shafts 63 and 65 of the auxiliary fins 33 and 35 to be connected to the first hole portions 68 </ b> A and 69 </ b> A of the cam holes 68 and 69. In addition, the auxiliary fins 33 and 35 are parallel to the second wall portion 22 by being positioned at the boundary between the second hole portions 68B and 69B (FIG. 9).

  When the main fin 31 is tilted from the above state, the transmission shafts 63 and 65 of the auxiliary fins 33 and 35 on the side close to the upstream end of the main fin 31 are positioned in the first holes 68A and 69A. The auxiliary fins 33 and 35 are set parallel to the second wall portion 22. By positioning the transmission shafts 65, 63 of the auxiliary fins 35, 33 far from the upstream end in the second holes 69 </ b> B, 68 </ b> B, the auxiliary fins 35, 33 are arranged at the downstream end to the inside of the ventilation path 20. It is made to incline with respect to the 2nd wall part 22 so that it may approach toward (FIG. 11, FIG. 12).

  (1A) Therefore, the clearance gap between each auxiliary fin 33 and 35 and the 2nd wall part 22 can be made small, and it can suppress that the air A for an air conditioning flows through this clearance gap. The pressure loss when the air-conditioning air A passes near the auxiliary fins 33 and 35 can be reduced.

  (1B) When the main fin 31 is inclined with respect to the second wall portion 22, the direction of the air conditioning air A flowing in the vicinity of the second wall portion 22 on the side far from the upstream end of the main fin 31 is the same. The auxiliary fins 35 and 33 on the side far from the upstream end can be changed to the inside of the ventilation path 20. Therefore, air-conditioning air A can be collected around the main fin 31 and the flow direction can be changed by the main fin 31. Therefore, the air-conditioning air A can be blown out from the outlet 14 toward the main fin 31, and the directivity of the air-conditioning air A when the main fin 31 is inclined with respect to both the second wall portions 22. Can be improved.

  (1C) Furthermore, when the main fin 31 is inclined with respect to the second wall portion 22, the auxiliary fins 33 and 35 on the side close to the upstream end of the main fin 31 are in a state parallel to the second wall portion 22. maintain. Therefore, even if the upstream end of the main fin 31 is brought close to the auxiliary fins 33 and 35, interference between the main fin 31 and the auxiliary fins 33 and 35 hardly occurs. Therefore, by arranging the auxiliary fins 33 and 35 and the second wall portion 22 on the side close to the upstream end of the main fin 31 at a location close to the main fin 31, the second direction (vertical direction) of the air-conditioning register is set. The dimensions can be reduced and the thickness can be further reduced.

  (1D) Although related to (1C) above, if the dimension in the second direction (vertical direction) of the air-conditioning register is sufficiently small and no further reduction in thickness is required, it is applied to the second wall portion 22. The upstream end of the main fin 31 inclined at the maximum angle obtained can be extended to a location near the auxiliary fins 33 and 35 that are parallel to the second wall portion 22 in the storage recess 24. The dimension (width) of the main fin 31 in the ventilation direction can be increased.

  (1E) Unlike (1D) above, when the upstream end of the main fin 31 is not extended, the auxiliary fins 33 and 35 on the side close to the upstream end of the main fin 31 even if the main fin 31 is greatly inclined. Difficult to interfere with. Therefore, the maximum inclination angle of the main fin 31 can be enlarged. In this case, there is an advantage that the angle that can be adjusted with respect to the blowing direction of the air-conditioning air A is widened.

  (1F) Further, the clearance between the upstream end of the main fin 31 that is inclined at the maximum angle that can be taken and the auxiliary fins 33 and 35 on the side close thereto is reduced, and the air-conditioning air A flowing through this clearance is reduced. can do. In the ventilation path 20, the air-conditioning air A flowing between the main fin 31 and the second wall portion 22 on the side close to the upstream end can be blown out in the direction in which the main fin 31 faces.

  (1G) Since the gear mechanism 59 including a plurality of gears is employed as a mechanism for transmitting the tilt of the main fin 31 to the cam member 67, the cam member 67 can be smoothly tilted according to the tilt of the main fin 31.

  (2) In the air-conditioning register described in Patent Document 1, the auxiliary fin whose downstream end has protruded to the inside of the ventilation path is inclined toward the downstream side of the main fin. Therefore, some air-conditioning air whose direction is changed by the auxiliary fins does not hit the main fin. It is difficult for the air-conditioning air to flow in the direction toward the main fin.

  In this respect, in the present embodiment, when the main fin 31 is inclined with respect to the second wall portion 22 by the maximum angle that can be taken, the auxiliary fins 35 and 33 on the side far from the upstream end of the main fin 31 are connected to the main fin 31. It is made to incline toward the fin 31 (FIG. 11).

  Therefore, in the ventilation path 20, the air-conditioning air A flowing between the main fin 31 and the second wall portion 22 on the side farther from the upstream end passes along the auxiliary fins 35 and 33 on the side farther from the upstream end. By making it flow, it can be made to contact the main fin 31 toward the main fin 31 side. As a result, more air-conditioning air A can be caused to flow in the direction toward the main fin 31.

  (3) The auxiliary fins 35 and 33 on the side farther from the upstream end of the main fin 31 inclined at the maximum angle that can be taken are centered in the main fin 31 with respect to the flow direction of the air conditioning air A in the ventilation path 20. It is made to incline toward the part used as a part (FIG. 11).

  Therefore, in the ventilation path 20, the air-conditioning air A flowing between the main fin 31 and the second wall portion 22 on the side farther from the upstream end passes along the auxiliary fins 35 and 33 on the side farther from the upstream end. By making it flow, it is possible to change the direction by applying more air-conditioning air A to the main fin 31 by directing it toward the upstream side of the central portion of the main fin 31.

  (4) In a state where the main fin 31 is inclined at the maximum angle that can be taken with respect to the second wall portion 22, a part of the downstream side of the operation knob 40 is connected to the auxiliary fin 35 far from the upstream end of the main fin 31. , 33 on the downstream side (FIG. 11).

  Therefore, even if the air for air conditioning A tries to flow in parallel between the main fin 31 and the auxiliary fins 35 and 33 on the side far from the upstream end of the main fin 31 in parallel to the second wall portion 22. The air A can be applied to the operation knob 40 to flow in the direction toward the main fin 31, and it is possible to restrict the air A from being blown out straight from the air outlet 14. Therefore, also in this respect, the directivity of the air-conditioning air A when the main fin 31 is inclined with respect to the second wall portion 22 by the maximum angle that can be taken can be improved.

  (5) The arms 62 and 64 are extended from the support shafts 34 and 36 of the auxiliary fins 33 and 35 in a direction orthogonal to the support shafts 34 and 36. Transmission shafts 63 and 65 are provided at locations deviated from the support shafts 34 and 36 of these arms 62 and 64 (FIG. 2).

  Therefore, these transmission shafts 63 and 65 can function as engaging portions for the auxiliary fins 33 and 35. When the cam member 67 tilts as the main fin 31 tilts and the cam holes 68 and 69 are displaced, the positions of the transmission shafts 63 and 65 in the cam holes 68 and 69 are changed. When the transmission shafts 63 and 65 are positioned in the second holes 68B and 69B of the cam holes 68 and 69, the tilt of the cam member 67 is transmitted to the transmission shafts 63 and 65 through the wall surfaces of the cam holes 68 and 69, and moved. The arms 62 and 64 and the auxiliary fins 33 and 35 can be tilted in the second direction (vertical direction) with the support shafts 34 and 36 as fulcrums. When the transmission shafts 63 and 65 are positioned in the first holes 68A and 69A, the tilt of the cam member 67 is not transmitted to the transmission shafts 63 and 65 through the cam holes 68 and 69, and the arms 62 and 64 and the auxiliary fins 33 are not transmitted. , 35 can be prevented from tilting.

(6) Cam holes 68 and 69 are provided in the cam member 67 supported so as to be tiltable in the second direction (vertical direction) by the shaft 28 with respect to the first wall portion 21 (FIG. 9).
Therefore, the cam member 67 can function as a transmission member, and the cam holes 68 and 69 can function as engaged portions. When the main fin 31 is tilted from a state parallel to the second wall portion 22, the cam member 67 is tilted with the shaft 28 as a fulcrum, and the pair of cam holes 68 and 69 are swung around the shaft 28. The positions of the transmission shafts 63 and 65 for the auxiliary fins 33 and 35 in the cam holes 68 and 69 are changed. When the transmission shafts 63 and 65 are positioned in the second holes 68B and 69B, the tilt of the cam member 67 is transmitted to the auxiliary fins 33 and 35. When the transmission shafts 63 and 65 are positioned in the first holes 68A and 69A, the cam member 67 is tilted. Can be prevented from being transmitted to the auxiliary fins 33, 35.

  (7) The gear mechanism 59 is a drive gear 61 provided on the support shaft 32 of the main fin 31 so as to be integrally rotatable, and a driven member provided on the cam member 67 so as to be integrally rotatable and meshed with the drive gear 61. It is comprised with the gear 66 (FIG. 9).

  Therefore, when the main fin 31 is tilted in the second direction (vertical direction) with the support shaft 32 as a fulcrum, the drive gear 61 is rotated around the support shaft 32 integrally with the main fin 31 to be driven gear 66. The driven gear 61 can be changed so that the driven gear 66 is integrated with the cam member 67 and rotated about the shaft 28.

  (8) In the above-mentioned Patent Document 1, the cam members for each auxiliary fin each having a cam hole are overlapped in the vehicle width direction, and the transmission shaft of the main fin is engaged with the intersection of both cam holes. The dimension of the register in the first direction (vehicle width direction) is increased.

  In this respect, in this embodiment, the transmission shafts 63 and 65 of the auxiliary fins 33 and 35 are engaged with the pair of cam holes 68 and 69 provided in the cam member 67 driven by the main fin 31. Not too much (not superposed). Therefore, the dimension of the air conditioning register in the first direction (vehicle width direction) can be reduced.

  (9) When the main fin 31 and the shut damper 70 are parallel to the second wall portion 22, the connecting rod 57 is projected onto the plane P perpendicular to the flow direction of the air-conditioning air A at the air outlet 14. The connecting rod 57 is disposed at a position where at least a part of the projection plane P2 is included in the projection plane P1 on which the main fin 31 and the shut damper 70 are projected (FIG. 4).

Therefore, the reduction in the actual opening area of the outlet 14 by the connecting rod 57 can be reduced, the ventilation resistance can be reduced, and pressure loss and noise can be suppressed.
Further, the overall size of the air-conditioning register can be made smaller than when the connecting rod 57 is disposed outside the ventilation path 20 (case 10).

  (10) With respect to the second direction (vertical direction), the connecting rod 57 is disposed at a location where the entire projection surface P2 of the connecting rod 57 is included in the projection surface P1 of the main fin 31 and the shut damper 70. (FIG. 4).

Therefore, it is possible to effectively reduce pressure loss and noise by reducing the actual opening area due to the connecting rod 57 and, consequently, by substantially reducing the ventilation resistance.
(11) The air outlet 14 is inclined with respect to the second wall portions 22. In the upstream fins 50, 51, a cutout portion 55 is provided in a portion of the second wall portion 22 on the side closer to the second wall portion 22 whose downstream end is located on the upstream side (upper second wall portion 22). In the notch 55, the connecting rod 57 intersects the upstream fins 50 and 51 (FIGS. 7 and 8).

  For this reason, the distance D1 from the downstream ends of the upstream fins 50 and 51 to the outlet 14 is long at the location where the downstream end is closer to the lower second wall portion 22 located on the downstream side, and the degree of reduction in directivity. Is big. However, the air-conditioning air A, which is not provided with the notch 55 in the upstream fins 50 and 51 and whose directivity is enhanced by the portion having the long length L1, can be caused to flow at a place where the distance D1 is long. .

  Moreover, in the location where the downstream end is closer to the upper second wall portion 22 positioned on the upstream side, the distance D2 from the downstream end of the upstream fins 50 and 51 to the outlet 14 is short, and the degree of directivity is reduced. small. The air-conditioning air A whose directivity has decreased due to the portion of the upstream fins 50 and 51 where the notch 55 is provided and the length L2 is shortened can be made to flow at a short distance D2.

  As a result, the degree to which the area downstream of the upstream fins 50 and 51 in the case 10 decreases the directivity varies depending on the site in the second direction (vertical direction), but the position of the notch 55 is changed. By appropriately setting, variation in directivity in the second direction (vertical direction) can be reduced.

  (12) With respect to the second direction (vertical direction), the notch portion 55 is provided only at the location where the connecting rod 57 intersects in the upstream fins 50 and 51 and the peripheral portion thereof (FIGS. 5 and 6).

Therefore, in the second direction (vertical direction), the proportion of the cutout portion 55 in the upstream fins 50 and 51 can be kept to the minimum necessary.
(13) With respect to the ventilation direction of the air-conditioning air A, the notch portion 55 is provided only at the location where the connecting rod 57 intersects in the upstream fins 50 and 51 and the peripheral portion thereof (FIGS. 5 and 6).

Therefore, the ratio of the notch 55 to the upstream fins 50 and 51 in the ventilation direction can be kept to the minimum necessary.
(14) The transmission shafts 63, 65 for each of the auxiliary fins 33, 35 are arranged more than the support shafts 34, 36 of the auxiliary fins 33, 35 with the main fin 31 being parallel to the second wall portion 22. It is made to position in the location which approached the center part (axis | shaft 28) between the two wall parts 22 (FIG. 9).

  Therefore, when the main fin 31 is inclined with respect to the second wall portion 22 by the maximum angle that can be taken, the peripheral portions of the first hole portions 68A and 69A in the cam member 67 are between the second wall portions 22 from the second wall portion 22. It can suppress that it protrudes outward about 2 directions (up-down direction), and interferes with the components of the case 10 periphery. As a result, space saving can be realized without impairing the air conditioning performance.

Note that the present invention can be embodied in another embodiment described below.
<About the through-hole part 53>
The shape and size of the through-hole portion 53 in the upstream fin 50 can avoid interference with the fork portion 41 accompanying the tilting of the upstream fin 50 in the first direction (vehicle width direction). On the condition that it exists, it may be changed to a different one from the above embodiment. FIG. 15 shows an example. In this example, the length in the ventilation direction of the through-hole portion 53 is maximized in the central portion in the second direction (vertical direction), and becomes shorter as the distance from the central portion increases in the same direction.

<Upstream fin group>
-An upstream fin group may be comprised by the number of fins different from the said embodiment. However, since the minimum number of fins that require the connecting rod 57 is 2, the upstream fin group needs to be constituted by two or more fins.

<Notch 55>
In the upstream fins 50 and 51, the portion where the cutout portion 55 is provided in the second direction (vertical direction) is the one in which the downstream end of the second wall portions 22 is located on the more upstream side (the second upper side). It can be changed on the condition that the part is closer to the wall 22).

  In FIG. 13, the notch 55 is located on the side closer to the portion where the downstream end is located on the more upstream side (upper second wall portion 22) from the location where the connecting rod 57 intersects. The example of a change provided over the end surface is shown. In this case, the notch 55 is the maximum size that can be taken in the second direction (vertical direction).

14 and 15 show a modified example in which the cutout portion 55 has an inclined surface that is inclined so as to be further away from the connecting rod 57 toward the upstream side.
In any of FIGS. 13 to 15, the notch portion 55 is expanded more than the embodiment described above. When the notch 55 is enlarged as described above, an effect of reducing noise can be obtained even when the upstream fins 50 and 51 are tilted in the first direction (vehicle width direction) with the support shaft 52 as a fulcrum. . This is because the upstream fins 50, 51 are tilted in the first direction (vehicle width direction) from the state parallel to the first wall portion 21, and are notched in the state inclined with respect to the first wall portion 21. This is because when the air-conditioning air A passes through 55, the wider one has less resistance and less noise.

  The notch 55 may be provided downstream of the support shaft 52 in the upstream fins 50 and 51. In this case, the notch 55 may extend from the downstream end face of the upstream fins 50, 51 toward the upstream end face.

<About connecting rod 57>
-The connection rod 57 should just be arrange | positioned in the location where at least one part of the projection surface P2 is contained in the projection surface P1 where the main fin 31 and the shut damper 70 are projected. Even in this case, the effect of suppressing pressure loss and noise can be obtained without increasing the size of the air-conditioning register.

<About the cam member 67>
The cam holes 68 and 69 in the cam member 67 may be configured by grooves (cam grooves) that do not penetrate the cam member 67.

<About the gear mechanism 59>
-The shape of the drive gear 61 and the driven gear 66 may be changed to a thing different from the said embodiment.

The gear mechanism 59 may be configured by a combination of three or more gears.
<About Shut Damper 70>
The position of the shut damper 70 in the second direction (vertical direction) may be changed. In this case, the shut damper 70 is disposed at a location where at least a part of the projection surface, more preferably at least the main part of the projection surface, and even more preferably the entire projection surface is included in the projection surface of the main fin 31. It is desirable.
