Description

  The present invention relates to a round air-conditioning register capable of changing the direction of an air outlet.

  The instrument panel of the vehicle incorporates an air-conditioning register that blows out air-conditioning air sent from the air-conditioning device from the air outlet. Conventionally, there is a round air-conditioning register having a round outlet (see, for example, Patent Document 1).

  A circular air conditioning register described in Patent Document 1 includes a cylindrical retainer, an outer cylinder located on the inner diameter side of the retainer, an inner cylinder located on the inner diameter side of the outer cylinder, and having a fluid flow path therein. And a plurality of dampers provided in the fluid flow path so as to be freely opened and closed. A shim is attached to the inner diameter side of the retainer. The inner peripheral surface of the shim and the outer peripheral surface of the outer cylinder facing the inner peripheral surface each have a spherical shape, and the outer cylinder is supported by a so-called ball joint so as to be freely directional with respect to the retainer (shim). ing. The outer cylinder is composed of a pair of front and rear cylindrical members, and holds the inner cylinder from the front and rear. Therefore, the inner cylinder is supported so as to be rotatable in the circumferential direction with respect to the outer cylinder.

  According to such a round air-conditioning register, the direction of the central axis of the outer cylinder with respect to the central axis of the retainer can be changed by a so-called ball joint, and the direction of the outlet can be changed. Further, when the inner cylinder is rotated to change the phase of the inner cylinder with respect to the outer cylinder, the openings of the plurality of dampers are changed in conjunction with this. As a result, the fluid flow path can be fully closed, fully opened, or air for air conditioning can be diffused.

  Incidentally, in the round air-conditioning register described in Patent Document 1, the outer cylinder is supported by a so-called ball joint with respect to the retainer (shim). Therefore, the posture and displacement of the outer cylinder are likely to be unstable. In this case, in order for the outer cylinder to be smoothly displaced, high dimensional accuracy is required for the inner peripheral surface of the shim and the outer peripheral surface of the outer cylinder. Therefore, when trying to reduce the size of the register, the dimensional accuracy of the inner peripheral surface of the shim and the outer peripheral surface of the outer cylinder must be further increased, which may increase the processing cost. Further, in this case, the smaller the radius of the outer cylinder, the greater the force required to rotate the outer cylinder with respect to the retainer.

  It is an object of the present invention to provide a round air-conditioning register that can change the direction of the air outlet in a plurality of directions with a simple configuration in addition to changing the air flow blowing range. .

  A round air-conditioning register for achieving the above object includes a retainer having a cylindrical portion, and a cylindrical portion that is located on the inner diameter side of the cylindrical portion and that is centered on a first shaft portion that extends in the radial direction of the cylindrical portion. An outer ring that is rotatably supported, and a second shaft portion that is located on an inner diameter side of the outer ring, extends in a radial direction of the outer ring, and extends in a direction different from the axial direction of the first shaft portion. An inner ring rotatably supported by the outer ring at the center, and a plurality of spokes extending radially from the central axis of the inner ring and dividing the inner diameter side space of the inner ring into a plurality of regions; A pair of spokes adjacent to each other around an operating member provided so as to be rotatable about the same central axis and an air flow guide surface and having a third shaft portion extending along a fan-shaped string in the plurality of regions. Each of which is pivotally supported by An air-conditioning air outlet is formed by the inner peripheral surface of the inner ring, and the inner ring is engaged with the plurality of fin bodies and the operation member is rotated. Accordingly, a guide portion for guiding the rotation of the plurality of fin bodies around the third shaft portion is provided, and the air flow guide surface with respect to the central axis of the inner ring by the rotation of the plurality of fin bodies. Each of the inclination angles can be changed.

  According to this configuration, the outer ring is rotatable about the first shaft portion with respect to the cylindrical portion of the retainer, and the second shaft extends in a direction different from the axial direction of the first shaft portion with respect to the outer ring. The inner ring is rotatable around the part. In addition, since the plurality of fin bodies are supported by the operation member and these fin bodies are engaged with the guide portion of the inner ring, the outer ring and the inner ring can be moved by swinging the operation member up and down or left and right, for example. It can be turned and the direction of the outlet can be changed. Thus, according to the said structure, an outer ring and an inner ring are stably supported via a 1st axial part and a 2nd axial part, respectively.

  Further, the inner diameter side of the inner ring is divided into a plurality of regions by a plurality of spokes of the operation member, and a plurality of fin bodies can be rotated around a third shaft portion along a sector-shaped string of the plurality of regions. Yes. When the operation member is rotated about the central axis of the inner ring, the rotation of the plurality of fin bodies around the third shaft portion is guided by the guide portion of the inner ring. Thereby, the inclination angle of each airflow guide surface with respect to the center axis of the inner ring is changed. For this reason, separately from rotating the outer ring and the inner ring by the operating member, the air flow blowing range can be changed by rotating the operating member to rotate the plurality of fin bodies.

Therefore, in addition to changing the air flow blowing range, it is possible to change the direction of the air outlet in a plurality of directions with a simple configuration.
In the round air-conditioning register, the plurality of fin bodies are at least a closed position where an inclination angle of the air flow guide surface with respect to a central axis of the inner ring is maximum, and the air flow guide surface is a center of the inner ring. It is preferably configured to be rotatable to a fully open position parallel to the axis.

  According to the same configuration, the plurality of fin bodies can be rotated to the closed position or the fully opened position by rotating the operation member to change the inclination angle of the air flow guide surface with respect to the center axis of the inner ring. . Therefore, the air blowing mode can be changed to the closed mode or the fully opened mode by a simple operation such as turning the operation member.

  In the round air-conditioning register, the plurality of fin bodies are rotated to a spot blowing position that is inclined so that the air flow guide surface is closer to the center axis of the inner ring toward the downstream side of the air-conditioning air flow direction. It is preferable that the configuration is possible.

  According to this configuration, the plurality of fin bodies can be rotated to the spot blowing position by rotating the operation member to change the inclination angle of the air flow guide surface with respect to the center axis of the inner ring. Therefore, the air blowing mode can be changed to the spot air blowing mode by a simple operation such as turning the operation member.

  In the round air conditioning register, the outer ring is provided with the first shaft portion on the outer peripheral surface, the retainer is provided with a support portion for supporting the first shaft portion, and the support portion is provided with the support portion. It is preferable that a shim that is fitted on the first shaft portion so as to be relatively rotatable and imparts a sliding resistance when the outer ring is rotated is assembled.

According to this configuration, when the outer ring is rotated, sliding resistance is imparted by the shim, so that a sense of moderation can be given to the operation of rotating the outer ring.
In the round air-conditioning register, the second shaft portion is provided on one of the inner peripheral surface of the outer ring and the outer peripheral surface of the inner ring, and the inner peripheral surface of the outer ring and the outer peripheral surface of the inner ring. On the other side, a support recess for supporting the second shaft portion is provided, and the support recess is fitted on the second shaft portion so as to be relatively rotatable so as to slide the inner ring. It is preferable that the shim which provides dynamic resistance is assembled | attached.

  According to this configuration, when the inner ring is rotated, sliding resistance is imparted by the shim, so that a sense of moderation can be given to the operation of rotating the inner ring.

  According to the present invention, in addition to changing the blowing range of the air flow, changing the direction of the outlet in a plurality of directions can be performed with a simple configuration.

Hereinafter, an embodiment of a round air-conditioning register will be described with reference to FIGS.
As shown in FIG. 1, the circular air-conditioning register (hereinafter referred to as a register) of the present embodiment is attached to an opening 12 provided in an instrument panel 11 of a vehicle. The air-conditioning air sent from the vehicle air conditioner is blown out into the vehicle compartment through the register 10. In the following description, the upstream side in the flow direction of the air-conditioning air in the register 10 may be referred to as the front side, and the downstream side in the flow direction may be referred to as the rear side.

  As shown in FIGS. 2 to 4, the register 10 includes a retainer 20 fixed to the opening 12 of the instrument panel 11. The retainer 20 is formed in a cylindrical portion 21 having an inner peripheral surface of an inner spherical shape, a flange 22 having a substantially square shape in front view extending from the outer peripheral surface of the cylindrical portion 21, and a central portion in the vertical direction of the front end portion of the cylindrical portion 21. And a pair of support portions 23, 24. The support portion 23 shown on the right side of FIG. 3 has an annular shape. Further, the support portion 24 shown on the left side of FIG. 3 has a C shape with the front side of the register cut out. Therefore, the central axis of the pair of support portions 23 and 24 is the first axis L1 along the radial direction of the cylindrical portion 21 of the retainer 20 (in this embodiment, the first axis L1 extending along the left-right direction in FIGS. 2 and 3). ).

  As shown in FIGS. 3 and 4, a circle having an outer spherical outer peripheral surface and an inner spherical inner peripheral surface along the inner peripheral surface of the cylindrical portion 21 on the inner diameter side of the cylindrical portion 21 of the retainer 20. An annular outer ring 30 is provided. As shown in FIG. 3, a pair of first shaft portions 31 that are rotatably supported by the pair of support portions 23 and 24 protrude from the outer peripheral surface of the outer ring 30. The pair of first shaft portions 31 are along the radial direction of the outer ring 30.

  An annular first shim 71 made of a soft resin material is fitted on the first shaft portion 31 shown on the left side in FIG. 3 so as to be relatively rotatable, and the first shim 71 is a left support portion. 24 is assembled so as not to be relatively rotatable. Therefore, the outer ring 30 is rotatably supported by the pair of support portions 23 and 24 of the retainer 20 around the pair of first shaft portions 31.

  As shown in FIGS. 3 and 4, a pair of second shaft portions 32 protrude from the upper and lower ends of the inner peripheral surface of the outer ring 30. The pair of second shaft portions 32 are along the second axis L2 extending along the radial direction of the outer ring 30 and perpendicular to the first axis L1, that is, the second axis L2 extending along the vertical direction.

  On the inner diameter side of the outer ring 30, an annular inner ring 40 having an outer spherical outer peripheral surface along the inner peripheral surface of the outer ring 30 is provided. A pair of support recesses 42 that rotatably support the pair of second shaft portions 32 of the outer ring 30 are formed at the upper end and the lower end of the outer peripheral surface of the inner ring 40.

  A second shim 72 made of a soft resin material is fitted on the second shaft portion 32 above the outer ring 30 so as to be relatively rotatable, and the second shim 72 is relatively rotated with respect to the upper support recess 42. It is assembled impossible. Therefore, the inner ring 40 is supported so as to be rotatable about the pair of second shaft portions 32.

  The inner peripheral surface of the inner ring 40 forms an air-conditioning air outlet 41 and is curved so as to be positioned closer to the inner diameter side of the register rear side. Three sets of guide groove pairs 43 are formed at equal intervals in the circumferential direction on the inner peripheral surface of the inner ring 40. In FIG. 3, only two guide groove pairs 43 are shown. Each guide groove pair 43 includes a first guide groove 44 and a second guide groove 45, and these guide grooves 44, 45 are parallel to each other and extend spirally.

  A front ring 50 is provided on the inner diameter side of the inner ring 40. The front ring 50 has three spokes 51 extending radially from the central axis C of the inner ring 40, and the space on the inner diameter side of the inner ring 40 is divided into three regions by the spokes 51. These three regions are substantially fan-shaped in plan view.

On both side surfaces of the tip portion of the spoke 51, support protrusions 52 project from the third axis L3 along the sector string adjacent to the spoke 51, respectively.
A fin body 60 is provided between a pair of adjacent spokes 51 of the front ring 50.

  The fin body 60 includes one main fin 61 and one sub fin 62 disposed on the outer peripheral side of the main fin 61, that is, in the vicinity of the inner peripheral surface of the inner ring 40. The main fin 61 and the sub fin 62 are connected to each other at both ends in the circumferential direction. Support cylinders 63 are formed at both ends of the fin body 60, and support protrusions 52 of the spokes 51 are externally inserted into the support cylinders 63 so as to be relatively rotatable. Accordingly, the three fin bodies 60 are respectively supported by the support protrusions 52 of the front ring 50 so as to be rotatable about the third axis L3.

The front and back surfaces of the main fin 61 and the sub fin 62 are air flow guide surfaces that guide the flow of air for air conditioning.
Further, two spherical protrusions 64 respectively engaged with the first guide groove 44 and the second guide groove 45 formed on the inner peripheral surface of the inner ring 40 are provided on the outer peripheral surface of the sub fin 62 of the fin body 60. , 65 are provided. Therefore, the front ring 50 is supported by the inner ring 40 through the three fin bodies 60 so as to be rotatable about the central axis C thereof.

Next, the operation of the register 10 of this embodiment will be described.
In the register 10, the outer ring 30 is rotatable about a first shaft portion 31 that extends to the left and right with respect to the cylindrical portion 21 of the retainer 20, and a second shaft portion 32 that extends vertically with respect to the outer ring 30. The inner ring 40 is rotatable around the center. Further, the three fin bodies 60 are supported by the front ring 50, and these fin bodies 60 are engaged with the first guide groove 44 and the second guide groove 45 of the inner ring 40. For this reason, the outer ring 30 and the inner ring 40 are rotated by swinging the front ring 50 up and down or left and right by picking the spoke 51 with a finger or the like, so that the direction of the air outlet 41 is set in two directions, up and down and left and right. Can be changed. Thus, the outer ring 30 and the inner ring 40 are stably supported via the first shaft portion 31 and the second shaft portion 32, respectively.

  Further, in this register 10, the air-conditioning air blowing mode is changed by changing the inclination angle of the fin body 60 by rotating the front ring 50 by picking the spoke 51 with a finger or the like. Here, the inclination angle of the fin body 60 is an angle formed by the central axis C of the inner ring 40 and the air flow guide surfaces of the main fin 61 and the sub fin 62 of the fin body 60. The inclination angle of the fin body 60 in the register 10 is changed in the following manner.

  In the fully open position shown in FIG. 6A, the fin body 60 has the air flow guide surfaces of the main fins 61 and the sub fins 62 parallel to the central axis C of the inner ring 40. At this time, of the two protrusions 64 and 65 provided on the fin body 60, the protrusion 64 positioned at the rear of the register is engaged with the first guide groove 44.

  When the front ring 50 is rotated from this state, as shown in FIG. 6B, the engaging position of the protrusion 64 in the first guide groove 44 is displaced rearward of the register and the inclination angle of the fin body 60 is increased. Become.

  When the front ring 50 is further rotated from this state, as shown in FIG. 6C, the inclination angle of the fin body 60 is further increased, and the two protrusions 64 and 65 are located in front of the register. 65 engages with the second guide groove 45. At this time, the two protrusions 64 and 65 are engaged with the first guide groove 44 and the second guide groove 45, respectively. At this time, according to the relative rotation of the front ring 50 with respect to the inner ring 40, the engaging positions of the protrusions 64 and 65 in the first guide groove 44 and the second guide groove 45 are respectively displaced in the register front-rear direction. The inclination angle of the fin body 60 is changed.

  When the front ring 50 is further rotated from this state, as shown in FIG. 6D, the protrusion 64 positioned at the rear of the register separates from the first guide groove 44, but the protrusion 65 positioned at the front of the register The engaged state with the second guide groove 45 is maintained. At this time, according to the relative rotation of the front ring 50 with respect to the inner ring 40, the engagement position of the protrusion 65 in the second guide groove 45 is displaced in the register front-rear direction, so that the inclination angle of the fin body 60 is changed. .

  As shown in FIGS. 7A to 7D, in such a register 10, when an operation for rotating the front ring 50 relative to the inner ring 40 (hereinafter referred to as a rotation operation) is performed, The ventilation mode of the air for air conditioning is changed by changing the inclination angle of the fin body 60 with the turning operation.

  That is, by increasing the amount of rotation of the front ring 50 in the counterclockwise direction from the position in the closed mode (FIG. 7A), the diffused air blowing mode (FIG. 7B) and the fully open mode (FIG. 7). (C)), the air blowing mode is changed in the order of the spot air blowing mode (FIG. 7 (d)).

  As shown by a solid line in FIG. 8, in the closed mode, the fin body 60 is in a position (closed position) where the inclination angle of the fin body 60 is maximized. At this time, the space between the inner peripheral surface of the inner ring 40 and the spokes 51 of the front ring 50 constituting the air-conditioning air outlet 41 is closed by the main fins 61 so that the air-conditioning air from the air outlet 41 is removed. The balloon is blocked.

  Further, as shown by a two-dot chain line in FIG. 8, in the fully open mode, the fin body 60 has a position where the air flow guide surfaces of the main fin 61 and the sub fin 62 are parallel to the central axis C of the inner ring 40. (Fully open position). At this time, the air-conditioning air is blown out from the outlet 41 along the central axis C of the inner ring 40. In the fully open mode, the pressure loss of the air-conditioning air when passing through the register 10 is minimized.

  As shown in FIG. 9, in the diffuse air blowing mode, the fin body 60 is at a position where the inclination angle of the fin body 60 is an intermediate angle between the closed mode and the fully open mode. That is, the fin body 60 is in the diffused air blowing position where the air flow guide surface is inclined so as to be separated from the center axis C of the inner ring 40 toward the front side of the register, that is, toward the downstream side in the air flow direction. At this time, the air-conditioning air is blown out from the air outlet 41 so as to spread radially, and as a result, the blowing range of the air flow into the vehicle interior is expanded.

  As shown in FIG. 10, in the spot blowing mode, the fin body 60 is such that the air flow guide surface is closer to the central axis C of the inner ring 40 toward the front side of the register, that is, toward the downstream side in the air flow direction. It is in the spot ventilation position which inclines to. At this time, the air-conditioning air is blown out from the outlet 41 so as to converge at one point on the central axis C of the inner ring 40.

According to the round air-conditioning register according to the present embodiment described above, the following effects can be obtained.
(1) The outer ring 30 of the register 10 is rotatably supported by the cylindrical portion 21 of the retainer 20 around the first shaft portion 31, and the inner ring 40 is orthogonal to the axis L <b> 1 of the first shaft portion 31. The biaxial portion 32 is supported by the outer ring 30 so as to be rotatable. An air outlet 41 for air-conditioning air is formed by the inner peripheral surface of the inner ring 40. In addition, a plurality of fin bodies 60 are engaged with the inner peripheral surface of the inner ring 40, and the rotation of the plurality of fin bodies 60 around the support protrusion 52 is performed in accordance with the rotation operation of the front ring 50, respectively. A first guide groove 44 and a second guide groove 45 for guiding are provided. Further, the inclination angle of each air flow guide surface with respect to the central axis C of the inner ring 40 can be changed by the rotation of the plurality of fin bodies 60. For this reason, the outer ring 30 and the inner ring 40 can be rotated by swinging the front ring 50 up and down and left and right, and the direction of the air outlet 41 can be changed. Further, the air flow blowing range can be changed by rotating the operating member to rotate the plurality of fin bodies 60. Further, the outer ring 30 and the inner ring 40 are stably supported via the first shaft portion 31 and the second shaft portion 32, respectively. Therefore, in addition to changing the air flow blowing range, it is possible to change the direction of the air outlet 41 in two directions with a simple configuration.

  Even when the register 10 is downsized, it is not necessary to reduce the shaft portions 31 and 32 in proportion to the size of the register 10. Therefore, unlike the technique described in Patent Document 1 in which the outer cylinder is supported by the ball joint with respect to the retainer, it is not necessary to increase the dimensional accuracy of the shaft portions 31 and 32 so much, and the register 10 can be easily downsized. Can be done. Further, even when the register 10 is downsized, the operability when the outer ring 30 and the inner ring 40 are rotated is unlikely to deteriorate.

  (2) There is no support member for pivotally supporting the outer ring 30 and the inner ring 40 around the central axis C of the inner ring 40. For this reason, the pressure loss of the air for air conditioning at the time of passing through the register 10 can be reduced.

  (3) The plurality of fin bodies 60 are in a closed position where the inclination angle of the air flow guide surface with respect to the central axis C of the inner ring 40 is maximum, and fully open so that the air flow guide surface is parallel to the central axis C of the inner ring 40. It is configured to be rotatable to a position. For this reason, by rotating the front ring 50 to change the inclination angle of the fin body 60, the plurality of fin bodies 60 can be rotated to the closed position or the fully opened position. Therefore, the air blowing mode can be changed to the closed mode or the fully opened mode by a simple operation such as rotating the front ring 50.

  (4) The plurality of fin bodies 60 are positions between the fully opened position and the closed position, and the air flow guide surfaces are separated from the central axis C of the inner ring 40 toward the downstream side in the flow direction of the air conditioning air. It is comprised so that rotation to the diffuser ventilation position which inclines to is possible. For this reason, the plurality of fin bodies 60 can be rotated to the diffusion air blowing position by rotating the front ring 50 to change the inclination angle of the fin bodies 60. Therefore, the air blowing mode can be changed to the diffusion air blowing mode by a simple operation such as rotating the front ring 50.

  (5) The plurality of fin bodies 60 are configured to be rotatable to a spot blowing position that is inclined so that the air flow guide surface is closer to the central axis C of the inner ring 40 toward the downstream side in the air-conditioning air flow direction. Yes. For this reason, the plurality of fin bodies 60 can be rotated to the spot blowing position by rotating the front ring 50 to change the inclination angle of the fin bodies 60. Therefore, the air blowing mode can be changed to the spot air blowing mode by a simple operation such as rotating the front ring 50.

  (6) The one support portion 24 of the retainer 20 is externally fitted to the one first shaft portion 31 of the outer ring 30 so as to be relatively rotatable, and is provided with a sliding resistance when the outer ring 30 is rotated. A first shim 71 is assembled.

  According to such a configuration, when the outer ring 30 is rotated, sliding resistance is provided by the first shim 71, so that a sense of moderation can be given to the operation of rotating the outer ring 30.

  (7) A second shim that is fitted to the support recess 42 of the inner ring 40 so as to be relatively rotatable with respect to the second shaft portion 32 of the outer ring 30 and provides a sliding resistance when the inner ring 40 is rotated. 72 is assembled.

  According to such a configuration, when the inner ring 40 is rotated, sliding resistance is imparted by the second shim 72, so that a sense of moderation can be given to the operation of rotating the inner ring 40.

<Modification>
In addition, the said embodiment can also be changed as follows, for example.
-The protrusion part of the fin body 60 and the guide groove of the inner ring 40 can also be made into one each.

-For example, the number of fin bodies 60 may be four.
As shown in FIG. 11, the inner ring portion 53 and the outer ring portion 54 can be set concentrically with respect to the front ring 50. In addition, about the same structure as the structure of the said embodiment among the structures shown in FIG. 11, the overlapping description is abbreviate | omitted by attaching | subjecting the same code | symbol. Further, a connecting portion 55 extending through the outer ring portion 54 from the outer peripheral surface of the inner ring portion 53 toward the radially outer side can be set between the adjacent spokes 51.

  The inner ring and the front ring can be changed as shown in FIG.

In addition, components corresponding to the configuration of the above-described embodiment are denoted by reference numerals obtained by adding “100”, and redundant description is omitted.

  That is, at the rear end portion of the inner ring 40, three spoke portions 46 extending radially from the central axis of the inner ring 40 are formed, and a support hole 47 is formed at the center portion. A support column 156 extending rearward along the central axis is formed at the rear end of the front ring 150, and the support column 156 is rotatably supported by the support hole 47.

  Further, as shown in FIG. 12, three operation spokes that extend radially from the central axis so as to be positioned between adjacent spokes 151 on the front side of the three spokes 151 that rotatably support the fin body 60. 157 may be provided integrally. In this case, each operation spoke 157 may be integrally formed with each spoke 151, or may be integrated after each operation spoke 157 and each spoke 151 are formed separately. Such operation spokes 157 are located in front of the spokes 151 and are separated from the fin body 60. For this reason, when operating the operation spoke 157 by picking it with a finger or the like, it is difficult for the finger to hit the fin body 60, and it is possible to appropriately avoid giving the user unpleasant feeling.

  The inner ring, the fin body, and the front ring can be changed as shown in FIG. In addition, about the same structure as the structure of the said embodiment among the structures shown in FIG. 13, the overlapping description is abbreviate | omitted by attaching | subjecting the same code | symbol. The components corresponding to the configuration of the above-described embodiment are denoted by the reference numerals with “200” added, and redundant description is omitted.

  The main fin 261 and the sub fin 262 of the fin body 260 are connected by a geared connecting portion 266 provided in the central portion in the circumferential direction. The geared connecting portion 266 is formed with a gear that meshes with the annular guide gear 243. Support protrusions 263 are formed on both ends of the fin body 260 in place of the support cylinder portion 63 of the above embodiment.

  The front ring 250 has a ring portion 258 that connects the tip portions of the spokes 251. Support holes 252 are formed on both side surfaces of the tip of the spokes 251 instead of the support protrusions 52 of the above-described embodiment, and the support protrusions 263 are extrapolated to the support holes 252.

  According to such a configuration, the gear formed on the front end surface of the guide gear 243 and the geared connecting portion 266 of the fin body 260 are engaged with each other, so that the three fin bodies are accompanied with the turning operation of the front ring 250. The rotation about the third axis L3 of 260 is guided respectively.

  The second shim 72 can be omitted. In this case, in order to ensure the moderation feeling of the operation of rotating the inner ring 40, a soft resin material is integrally formed on the outer peripheral surface of the second shaft portion 32 of the outer ring 30, or the support recess 42 of the inner ring 40 is formed. It is preferable to integrally mold a soft resin material on the inner peripheral surface.

  The first shim 71 can be omitted. In this case, in order to secure a sense of moderation in the operation of rotating the outer ring 30, a soft resin material is integrally formed on the outer peripheral surface of the first shaft portion 31 of the outer ring 30, or the inner portion of the support portion 24 of the retainer 20. It is preferable to integrally mold a soft resin material on the peripheral surface.

  -The rotation range of the fin body 60 can also be changed suitably. For example, the fin body 60 can be configured to rotate from the closed position to the fully opened position but not to the spot blowing position. Further, the fin body 60 can be configured not to rotate to the fully open position parallel to the central axis C of the inner ring 40.
