　以下、本実施の形態を、図面を用いて詳細に説明する。
  図１～図８は、この実施の形態を説明するためのものである。 Hereinafter, the present embodiment will be described in detail with reference to the drawings.
1 to 8 are for explaining this embodiment.
　＜構成＞以下、この実施例の構成について説明する。 <Configuration> The configuration of this embodiment will be described below.
　自動車などの車両における、車室内に空調装置のエアを吹出すためのエア吹出口を設ける。このエア吹出口に、図１に示すような風向調整装置１を設ける。 In an automobile or other vehicle, an air outlet is provided in the passenger compartment to blow out air from the air conditioner. A wind direction adjusting device 1 as shown in FIG. 1 is provided at the air outlet.
　風向調整装置１は、エアを吹出す吹出口部材３の内部に、エアの風向を調整可能なルーバ４～６を配設したものである。ルーバ４～６は端部に設けた回転軸７を、吹出口部材３に設けた軸穴部１１に対し回動自在に軸支する。 The wind direction adjusting device 1 is provided with louvers 4 to 6 capable of adjusting the air direction of air inside an outlet member 3 that blows out air. The louvers 4 to 6 rotatably support a rotating shaft 7 provided at an end portion thereof with respect to a shaft hole portion 11 provided in the air outlet member 3.
　ここで、風向調整装置１は、例えば、インストルメントパネルに設けたベンチレーターグリルなどとすることができる。風向調整装置１は、エアの風向を上下方向１５や左右方向１６に調整するためのものである。この実施例では、エアの風向を上下方向１５に調整するものとしているが、左右方向１６に調整するものとしても良い。 Here, the wind direction adjusting device 1 can be, for example, a ventilator grill provided on the instrument panel. The wind direction adjusting device 1 is for adjusting the air wind direction in the vertical direction 15 and the horizontal direction 16. In this embodiment, the air wind direction is adjusted in the vertical direction 15, but may be adjusted in the horizontal direction 16.
　吹出口部材３は、硬質の樹脂によって構成した筒枠状の部材である。吹出口部材３には、矩形状をしたものや円形状（または球状）をしたものなどが存在している。 The air outlet member 3 is a cylindrical frame-shaped member made of hard resin. The blower outlet member 3 has a rectangular shape or a circular shape (or a spherical shape).
　ルーバ４～６は、硬質の樹脂によって構成した羽根状部材である。回転軸７は、各ルーバ４～６の長手方向（この場合には、左右方向１６）の両端部に同一軸線上に位置するように設ける。 The louvers 4 to 6 are blade-shaped members made of hard resin. The rotation shaft 7 is provided so as to be positioned on the same axis line at both ends of the louvers 4 to 6 in the longitudinal direction (in this case, the left-right direction 16).
　軸穴部１１は、吹出口部材３の回転軸７と対応する位置（ルーバ４～６の長手方向と交差する辺部など）に直接設けることができる。また、軸穴部１１は、吹出口部材３とは別体の軸受部材１２（図３参照）に設けることができる。軸受部材１２は、吹出口部材３における、各ルーバ４～６の両端部と対応する位置に設けた取付座に設置される。上記により、吹出口部材３に設けた軸穴部１１は、吹出口部材３に直接設けた軸穴部１１、および、吹出口部材３に（軸受部材１２などを介して）間接的に設けた軸穴部１１を含むものとなる。 The shaft hole portion 11 can be directly provided at a position corresponding to the rotation shaft 7 of the air outlet member 3 (such as a side portion intersecting the longitudinal direction of the louvers 4 to 6). Further, the shaft hole portion 11 can be provided in a bearing member 12 (see FIG. 3) that is separate from the air outlet member 3. The bearing member 12 is installed on a mounting seat provided at a position corresponding to both ends of the louvers 4 to 6 in the air outlet member 3. As described above, the shaft hole portion 11 provided in the air outlet member 3 is indirectly provided in the shaft hole portion 11 provided directly in the air outlet member 3 and the air outlet member 3 (via the bearing member 12 or the like). The shaft hole portion 11 is included.
　この実施例では、ルーバ４～６の操作力を、回転軸７と軸穴部１１との間の摩擦力を利用することなく発生し得るようにする。よって、回転軸７と軸穴部１１との間の径方向の寸法管理はシビアにしなくても良いものとなる。また、ルーバ４～６の操作力を、吹出口部材３（や軸受部材１２）の内面とルーバ４～６の端部との間の摩擦力を利用することなく発生し得るようにする。よって、吹出口部材３の内面の幅寸法とルーバ４～６の長さとの間の寸法管理はシビアにしなくても良いものとなる。 In this embodiment, the operating force of the louvers 4 to 6 can be generated without using the frictional force between the rotating shaft 7 and the shaft hole 11. Therefore, the radial dimension management between the rotating shaft 7 and the shaft hole portion 11 does not need to be severe. Further, the operation force of the louvers 4 to 6 can be generated without using the frictional force between the inner surface of the outlet member 3 (or the bearing member 12) and the end portions of the louvers 4 to 6. Therefore, the size control between the width dimension of the inner surface of the outlet member 3 and the length of the louvers 4 to 6 does not have to be severe.
　以上のような基本的な構成に対し、この実施例では、以下のような構成を備えるようにしている。 In contrast to the basic configuration as described above, this embodiment has the following configuration.
　（１）軸穴部１１の奥部に、回転軸７の端部を軸方向（この場合には、左右方向１６）に圧接することで摺動抵抗を発生可能な摺動抵抗発生部材２１を設ける。 (1) The sliding resistance generating member 21 capable of generating sliding resistance by pressing the end of the rotating shaft 7 in the axial direction (in this case, the left-right direction 16) at the back of the shaft hole portion 11 is provided.

　ここで、摺動抵抗発生部材２１は、吹出口部材３やルーバ４～６とは別の部材によって構成することができる。摺動抵抗発生部材２１には、例えば、シリコーンゴムやエラストマーなどのように大きな摺動抵抗を発生可能な柔軟な素材を使用するのが好ましい。摺動抵抗発生部材２１は、吹出口部材３に設けた収容部２５の内部に収容設置することができる。収容部２５は、軸穴部１１の外方端を包囲する空間（摺動抵抗発生部材収容空間）を画成するものなどとすることができる。 Here, the sliding resistance generating member 21 can be constituted by a member different from the air outlet member 3 and the louvers 4-6. For the sliding resistance generating member 21, it is preferable to use a flexible material capable of generating a large sliding resistance such as silicone rubber or elastomer. The sliding resistance generating member 21 can be accommodated and installed inside the accommodating portion 25 provided in the air outlet member 3. The accommodating part 25 can define a space (sliding resistance generating member accommodating space) surrounding the outer end of the shaft hole part 11.
　（２）吹出口部材３にルーバ４～６を複数枚並設する。
  また、複数枚のルーバ４～６を一体的に回動可能となるようにリンク部材３１で連結する。
  そして、リンク部材３１を、回転軸７の端部を摺動抵抗発生部材２１へ向けて軸方向に付勢可能な付勢部材３２にしても良い。 (2) A plurality of louvers 4 to 6 are arranged on the outlet member 3 in parallel.
Further, the plurality of louvers 4 to 6 are connected by a link member 31 so as to be integrally rotatable.
The link member 31 may be a biasing member 32 that can bias the end of the rotating shaft 7 toward the sliding resistance generating member 21 in the axial direction.
　ここで、複数枚のルーバ４～６は、吹出口部材３の出口開口の面に沿って互いに平行に配設する。ルーバ４～６は、３枚以上設けるようにするのが好ましい。リンク部材３１は、各ルーバ４～６に設けた連結軸３４～３６の間を連結する。連結軸３４～３６は、回転軸７と平行な方向へ延びるようにする。リンク部材３１は、連結軸３４～３６を軸支可能な連結用軸穴３７～３９を備えている。連結軸３４～３６は、ルーバ４～６の端部近傍における、回転軸７の後側（エアの吹き出し方向の上流側）の位置に設けるのが好ましい。連結軸３４～３６は、ルーバ４～６の摺動抵抗発生部材２１側の端部近傍に設けるのが好ましい。 Here, the plurality of louvers 4 to 6 are arranged in parallel to each other along the surface of the outlet opening of the outlet member 3. Three or more louvers 4 to 6 are preferably provided. The link member 31 connects the connecting shafts 34 to 36 provided in the louvers 4 to 6. The connecting shafts 34 to 36 extend in a direction parallel to the rotating shaft 7. The link member 31 includes connecting shaft holes 37 to 39 that can support the connecting shafts 34 to 36. The connecting shafts 34 to 36 are preferably provided at positions on the rear side (upstream side in the air blowing direction) of the rotating shaft 7 in the vicinity of the ends of the louvers 4 to 6. The connecting shafts 34 to 36 are preferably provided near the ends of the louvers 4 to 6 on the sliding resistance generating member 21 side.
　この際、ルーバ４～６の操作力を、連結軸３４～３６と連結用軸穴３７～３９との間の摩擦力を利用することなく発生し得るようにする。よって、連結軸３４～３６と連結用軸穴３７～３９との間の径方向の寸法管理はシビアにしなくても良いものとなる。 At this time, the operating force of the louvers 4 to 6 can be generated without using the frictional force between the connecting shafts 34 to 36 and the connecting shaft holes 37 to 39. Therefore, the dimensional management between the connecting shafts 34 to 36 and the connecting shaft holes 37 to 39 may not be severe.
　（３）そして、付勢部材３２は、板バネ４１としても良い。 (3) The biasing member 32 may be a leaf spring 41.
　ここで、板バネ４１は、金属製または樹脂製のものとする。板バネ４１は、連結用軸穴３７～３９と垂直な面を有してルーバ４～６の並設方向へ延びている。 Here, the leaf spring 41 is made of metal or resin. The leaf spring 41 has a surface perpendicular to the connecting shaft holes 37 to 39 and extends in the direction in which the louvers 4 to 6 are juxtaposed.
　（４）摺動抵抗発生部材２１は、並設方向の中間に位置するルーバ５の回転軸７ａに対して設けても良い。 (4) The sliding resistance generating member 21 may be provided with respect to the rotating shaft 7a of the louver 5 located in the middle of the juxtaposed direction.
　ここで、中間に位置するルーバ５は、並設方向の両側（図中上下）に位置するルーバ４，６を除いたものである。ルーバ４～６が３枚以上ある場合には、並設方向の最も中央に位置するルーバ５とするのが好ましい。 Here, the louver 5 located in the middle is obtained by removing the louvers 4 and 6 located on both sides (upper and lower in the figure) in the juxtaposed direction. When there are three or more louvers 4 to 6, it is preferable that the louver 5 is located at the center of the juxtaposed direction.
　並設方向の中間に位置するルーバ５には、手動操作のための操作部２６（図１参照）を設けることができる。操作部２６は、ルーバ４～６の向きを調整したり、ルーバ４～６の背後に設置した別のルーバの向きを調整したりするものである。 The louver 5 located in the middle of the juxtaposed direction can be provided with an operation unit 26 (see FIG. 1) for manual operation. The operation unit 26 adjusts the direction of the louvers 4 to 6 and adjusts the direction of another louver installed behind the louvers 4 to 6.
　（５）並設方向の両側に位置するルーバ４，６と、並設方向の中間に位置するルーバ５との間に、並設方向の中間に位置するルーバ５を摺動抵抗発生部材２１へ向けて軸方向に付勢可能となるよう弾性力を蓄積した付勢部材３２を介装しても良い。 (5) Between the louvers 4 and 6 located on both sides in the juxtaposed direction and the louver 5 located in the middle of the juxtaposed direction, the louver 5 located in the middle of the juxtaposed direction is moved to the sliding resistance generating member 21. An urging member 32 in which an elastic force is accumulated may be interposed so as to be urged in the axial direction.
　ここで、付勢部材３２を板バネ４１とした場合、例えば、並設方向の両側に位置するルーバ４，６の連結軸３４，３６と、並設方向の中間に位置するルーバ５の連結軸３５とを、軸方向の位置をズラして設置する。 Here, when the urging member 32 is a leaf spring 41, for example, the connecting shafts 34 and 36 of the louvers 4 and 6 located on both sides in the juxtaposed direction and the connecting shaft of the louver 5 located in the middle of the juxtaposed direction. 35 is installed with the axial position shifted.
　この際、並設方向の両側に位置するルーバ４，６の連結軸３４，３６が、摺動抵抗発生部材２１に近くなり（または、ルーバ４，６の端部寄りに位置し）、並設方向の中間に位置するルーバ５の連結軸３５が、摺動抵抗発生部材２１から遠くなる（または、ルーバ５の中央寄りに位置する）ように配置する。 At this time, the connecting shafts 34 and 36 of the louvers 4 and 6 located on both sides in the juxtaposed direction are close to the sliding resistance generating member 21 (or located near the ends of the louvers 4 and 6). The connecting shaft 35 of the louver 5 located in the middle of the direction is arranged so as to be far from the sliding resistance generating member 21 (or located closer to the center of the louver 5).
　次に、並設方向の両側に位置するルーバ４，６の連結軸３４，３６と、並設方向の中間に位置するルーバ５の連結軸３５とに対して、板バネ４１が、軸方向へ移動しないように軸支する。そのために、例えば、連結軸３４，３６と連結軸３５との向きを反対に設けたり、または、連結軸３４～３６の端部に抜け止め用のストッパを設けたりする。 Next, the leaf spring 41 is moved in the axial direction with respect to the connecting shafts 34 and 36 of the louvers 4 and 6 located on both sides in the juxtaposed direction and the connecting shaft 35 of the louver 5 located in the middle of the juxtaposed direction. It is supported so that it does not move. For this purpose, for example, the connecting shafts 34 and 36 and the connecting shaft 35 are provided in opposite directions, or stoppers are provided at the end portions of the connecting shafts 34 to 36.
　この場合には、並設方向の両側に位置するルーバ４，６の連結軸３４，３６をルーバ４，６の端部側へ向け、並設方向の中間に位置するルーバ５の連結軸３５をルーバ５の中央側へ向けるようにしている。そのために、並設方向の中間に位置するルーバ５の端部に切欠部５ａ（図４参照）や孔部を設けて、切欠部５ａ内に連結軸３４，３６と反対向きに連結軸３５を設けるようにしても良い。 In this case, the connecting shafts 34 and 36 of the louvers 4 and 6 located on both sides in the juxtaposed direction are directed toward the end portions of the louvers 4 and 6, and the connecting shaft 35 of the louver 5 located in the middle of the juxtaposed direction is provided. The louver 5 is directed toward the center. For this purpose, a notch 5a (see FIG. 4) and a hole are provided at the end of the louver 5 located in the middle of the juxtaposed direction, and the connecting shaft 35 is disposed in the notch 5a in the direction opposite to the connecting shafts 34 and 36. You may make it provide.
　そして、並設方向の両側に位置するルーバ４，６の連結軸３４，３６と、並設方向の中間に位置するルーバ５の連結軸３５との間に、直線状をした板バネ４１を中間部が摺動抵抗発生部材２１から遠くなる方向に撓めた状態で介装する。 And, between the connecting shafts 34 and 36 of the louvers 4 and 6 located on both sides in the juxtaposed direction and the connecting shaft 35 of the louver 5 located in the middle of the juxtaposed direction, a linear leaf spring 41 is interposed. The part is interposed in a state where it is bent in a direction away from the sliding resistance generating member 21.
　以上により、板バネ４１が復帰しようとする弾性力によって、並設方向の両側に位置するルーバ４，６の連結軸３４，３６は、摺動抵抗発生部材２１と反対の側へ付勢され、並設方向の中間に位置するルーバ５の連結軸３５は、摺動抵抗発生部材２１の側へ付勢されることになる。 As described above, the connecting shafts 34 and 36 of the louvers 4 and 6 located on both sides in the juxtaposed direction are urged to the side opposite to the sliding resistance generating member 21 by the elastic force that the leaf spring 41 is to return. The connecting shaft 35 of the louver 5 located in the middle of the juxtaposed direction is biased toward the sliding resistance generating member 21 side.
　なお、ルーバ４～６が３枚以上ある場合には、その他のルーバに設ける連結軸は、付勢部材３２による軸方向の付勢力の影響を受けないようにするのが好ましい。例えば、連結軸と、リンク部材３１の連結用軸穴との間に隙間を設けるなどして、連結軸がリンク部材３１の連結用軸穴から抜けない範囲で軸方向へ移動できるようにする。 When there are three or more louvers 4 to 6, it is preferable that the connecting shafts provided on the other louvers are not affected by the urging force in the axial direction by the urging member 32. For example, a gap is provided between the connecting shaft and the connecting shaft hole of the link member 31 so that the connecting shaft can move in the axial direction as long as the connecting shaft does not come out of the connecting shaft hole of the link member 31.
　（６）ルーバ５の回転軸７ａの端部に抵抗増大部５１を設けても良い。
  そして、摺動抵抗発生部材２１に、抵抗増大部５１を受ける受部５２を設けても良い。 (6) The resistance increasing portion 51 may be provided at the end of the rotating shaft 7 a of the louver 5.
The sliding resistance generating member 21 may be provided with a receiving portion 52 that receives the resistance increasing portion 51.
　ここで、抵抗増大部５１は、摺動抵抗発生部材２１との間で摺動抵抗を増大できればどのようなものでも良い。抵抗増大部５１は、例えば、回転軸７ａの端部に一体に設けた、回転軸７ａよりも径の大きい拡径部などとすることができる。そして、例えば、図２に示すように、受部５２を、軸方向の外方に凹む、すり鉢状（奥側へ向かって狭くなる斜面部分を少なくとも一部に有する回転対称形状）の凹部５５を有するものとして、抵抗増大部５１の外周部や外面などをすり鉢状の凹部５５の斜面で受けるようにしても良い。 Here, the resistance increasing portion 51 may be anything as long as the sliding resistance can be increased with the sliding resistance generating member 21. The resistance increasing portion 51 can be, for example, a diameter-enlarged portion that is integrally provided at the end of the rotating shaft 7a and has a larger diameter than the rotating shaft 7a. And, for example, as shown in FIG. 2, a concave portion 55 having a cone shape (a rotationally symmetric shape having at least a part of a sloping portion narrowing toward the back side) is formed by recessing the receiving portion 52 outward in the axial direction. As an example, the outer peripheral portion or the outer surface of the resistance increasing portion 51 may be received by the inclined surface of the mortar-shaped concave portion 55.
　また、例えば、図５に示すように、受部５２を平坦面にして、抵抗増大部５１の端面を面全体で受けるようにしても良い。 Further, for example, as shown in FIG. 5, the receiving portion 52 may be a flat surface and the end surface of the resistance increasing portion 51 may be received by the entire surface.
　なお、抵抗増大部５１を有する回転軸７ａを軸穴部１１へ装着できるようにするために、軸穴部１１には、回転軸７ａを横から通せるようにするスリット部１１ａなどを設けても良い。 In order to allow the rotation shaft 7a having the resistance increasing portion 51 to be mounted in the shaft hole portion 11, the shaft hole portion 11 is provided with a slit portion 11a for allowing the rotation shaft 7a to pass from the side. Also good.
　＜作用＞以下、この実施例の作用について説明する。 <Operation> The operation of this embodiment will be described below.
　車室内で空調装置を作動すると、空調装置のエアはエア吹出口から吹出される。そして、乗員は、このエア吹出口に設けた風向調整装置１によって、風向を調整することができる。 When the air conditioner is operated in the passenger compartment, air from the air conditioner is blown out from the air outlet. And a passenger | crew can adjust a wind direction with the wind direction adjustment apparatus 1 provided in this air blower outlet.
　風向調整装置１は、ルーバ４～６の向きを変えることによって風向を調整する。ルーバ４～６の向き変える際には、ルーバ４～６に操作力を加えることになる。このルーバ４～６に加える操作力を安定したものにすることで、風向調整装置１は、操作感の良いものとすることができる。 The wind direction adjusting device 1 adjusts the wind direction by changing the direction of the louvers 4 to 6. When changing the direction of the louvers 4 to 6, an operating force is applied to the louvers 4 to 6. By stabilizing the operating force applied to the louvers 4 to 6, the wind direction adjusting device 1 can have a good operational feeling.
　＜効果＞この実施例によれば、以下のような効果を得ることができる。 <Effect> According to this embodiment, the following effects can be obtained.
　（効果１）吹出口部材３の軸穴部１１の奥部に摺動抵抗発生部材２１を設けた。そして、摺動抵抗発生部材２１と、ルーバ４～６の回転軸７の端部とを軸方向に圧接することで、ルーバ４～６の回転に対して摺動抵抗を発生させるようにした。これにより、摺動抵抗発生部材２１と回転軸７の端部との軸方向の圧接によって発生する摺動抵抗を利用してルーバ４～６の操作力を得ることができる。 (Effect 1) A sliding resistance generating member 21 was provided in the inner part of the shaft hole portion 11 of the outlet member 3. Then, the sliding resistance generating member 21 and the end of the rotating shaft 7 of the louvers 4 to 6 are pressed against each other in the axial direction to generate sliding resistance against the rotation of the louvers 4 to 6. Thereby, the operating force of the louvers 4 to 6 can be obtained by utilizing the sliding resistance generated by the axial pressure contact between the sliding resistance generating member 21 and the end of the rotating shaft 7.
　そのため、例えば、摺動抵抗発生部材２１を設けていない図７、図８の場合のように、例えば、ルーバ４～６の回転軸７と吹出口部材３の軸穴部１１との間の摩擦力や、吹出口部材３の内面とルーバ４～６の端部との間の摩擦力や、連結軸３４～３６と連結用軸穴３７～３９との間の摩擦力、などによってルーバ４～６の操作力を得るようにしたものと比べて、容易かつ確実に操作力の設定を行うことができる。 Therefore, for example, as in the case of FIGS. 7 and 8 in which the sliding resistance generating member 21 is not provided, for example, the friction between the rotating shaft 7 of the louvers 4 to 6 and the shaft hole portion 11 of the outlet member 3. The louvers 4 to 6 are caused by the force, the frictional force between the inner surface of the outlet member 3 and the ends of the louvers 4 to 6, the frictional force between the connecting shafts 34 to 36 and the connecting shaft holes 37 to 39, etc. Compared with the one in which the operation force of 6 is obtained, the operation force can be set easily and reliably.
　よって、回転軸７と軸穴部１１との間の径方向の（０．１ｍｍレベルの）厳密な寸法管理や、吹出口部材３の内面とルーバ４～６の端部との間の（０．１ｍｍレベルの）厳密な寸法管理や、連結軸３４～３６と連結用軸穴３７～３９との間の径方向の（０．１ｍｍレベルの）厳密な寸法管理などを不要化することができる。また、吹出口部材３とルーバ４～６との間の摩擦力を利用して行う場合の操作力の設定の限界をなくすことができる。 Therefore, strict dimensional control (on the level of 0.1 mm) between the rotating shaft 7 and the shaft hole portion 11 and (0) between the inner surface of the outlet member 3 and the ends of the louvers 4 to 6 are performed. Strict dimensional control (.1 mm level) and radial dimensional management (0.1 mm level) between the connecting shafts 34 to 36 and the connecting shaft holes 37 to 39 can be eliminated. . Further, it is possible to eliminate the limit of setting the operation force when the friction force between the air outlet member 3 and the louvers 4 to 6 is used.
　即ち、吹出口部材３やルーバ４～６とは別部材でできた摺動抵抗発生部材２１を用いることで、自由度が増えるため、発生する摺動抵抗をより細かくより繊細に設定することができるようになるので、設計通りの操作力を有するルーバ４～６を容易且つ再現性良く製造することが可能になる。そのため、容易にルーバ４～６の操作力を一定にすることができる。或いは、操作力が一定のルーバ４～６を容易且つ確実に生産することができる。しかも、快適な操作力の実現を図ることができる。 In other words, since the degree of freedom increases by using the sliding resistance generating member 21 made of a member different from the outlet member 3 and the louvers 4 to 6, the generated sliding resistance can be set more finely and more delicately. Thus, the louvers 4 to 6 having the designed operating force can be manufactured easily and with good reproducibility. Therefore, the operating force of the louvers 4 to 6 can be easily made constant. Alternatively, the louvers 4 to 6 having a constant operating force can be easily and reliably produced. In addition, a comfortable operating force can be achieved.
　更に、軸穴部１１の奥部に摺動抵抗発生部材２１を設けることにより、外部から見えない位置に摺動抵抗発生部材２１を設置することができる。 Furthermore, by providing the sliding resistance generating member 21 at the back of the shaft hole portion 11, the sliding resistance generating member 21 can be installed at a position that cannot be seen from the outside.
　（効果２）複数枚のルーバ４～６をリンク部材３１で連結して一体的に回動可能にする。この際、複数枚のルーバ４～６間を連結するリンク部材３１を付勢部材３２にしても良い。これにより、リンク部材３１を付勢部材３２にするだけで、部品点数を増やすことなく、回転軸７の端部を摺動抵抗発生部材２１に圧接させることができる。よって、風向調整装置１の構造複雑化を防止できる。 (Effect 2) A plurality of louvers 4 to 6 are connected by a link member 31 to be integrally rotatable. At this time, the link member 31 that connects the plurality of louvers 4 to 6 may be the urging member 32. Thereby, the end part of the rotating shaft 7 can be press-contacted with the sliding resistance generation member 21 only by making the link member 31 into the biasing member 32, without increasing a number of parts. Therefore, the structure of the wind direction adjusting device 1 can be prevented from becoming complicated.
　また、リンク部材３１とルーバ４～６との接続部分に発生する摩擦力などに頼らずに、ルーバ４～６の操作力を得ることが可能になる。更に、付勢部材３２によって回転軸７の端部を摺動抵抗発生部材２１に圧接することで、ルーバ４～６の軸方向のガタ付きを抑制することができる。更に、複数枚のルーバ４～６の回転軸７間のピッチや吹出口部材３の軸穴部１１間のピッチの厳密な寸法管理を不要化することも可能となる。 Further, it is possible to obtain the operating force of the louvers 4 to 6 without depending on the frictional force generated at the connecting portion between the link member 31 and the louvers 4 to 6. Furthermore, the end of the rotating shaft 7 is brought into pressure contact with the sliding resistance generating member 21 by the urging member 32, whereby the louvers 4 to 6 can be prevented from rattling in the axial direction. Furthermore, it is possible to eliminate the need for strict dimensional control of the pitch between the rotating shafts 7 of the plurality of louvers 4 to 6 and the pitch between the shaft hole portions 11 of the outlet member 3.
　（効果３）付勢部材３２を板バネ４１にしても良い。これにより、回転軸７の端部を安定して摺動抵抗発生部材２１に圧接することができる。また、付勢部材３２に板バネ４１を用いることで、温度変化や温度変化による寸法変化などの環境要因によって操作力が変化するのを、有効に防止できる。更に、板バネ４１は、容易にリンク部材３１に加工することができる。そして、板バネ４１は薄型の部材であるため、風向調整装置１を大型化することなく設置することができる。 (Effect 3) The biasing member 32 may be a leaf spring 41. As a result, the end of the rotating shaft 7 can be stably brought into pressure contact with the sliding resistance generating member 21. Further, by using the leaf spring 41 for the urging member 32, it is possible to effectively prevent the operating force from changing due to environmental factors such as a temperature change and a dimensional change due to the temperature change. Further, the leaf spring 41 can be easily processed into the link member 31. And since the leaf | plate spring 41 is a thin member, the wind direction adjusting apparatus 1 can be installed without enlarging.
　（効果４）摺動抵抗発生部材２１を、複数枚並設したルーバ４～６における並設方向の中間に位置するルーバ５の回転軸７ａに対して設けても良い。並設方向の中間に位置するルーバ５は、手で直接操作するものとなるため、中間に位置するルーバ５を動かした時に、摺動抵抗発生部材２１による摺動抵抗が操作力として直接手に伝わることになるので、操作感をより良くすることができる。 (Effect 4) The sliding resistance generating member 21 may be provided with respect to the rotating shaft 7a of the louver 5 positioned in the middle of the juxtaposed direction of the plural louvers 4 to 6 arranged side by side. Since the louver 5 located in the middle of the juxtaposed direction is directly operated by hand, when the louver 5 located in the middle is moved, the sliding resistance generated by the sliding resistance generating member 21 is directly applied to the hand as an operating force. Because it is transmitted, the operational feeling can be improved.
　（効果５）付勢部材３２を、並設方向の両側に位置するルーバ４，６と、並設方向の中間に位置するルーバ５との間に、並設方向の中間に位置するルーバ５を摺動抵抗発生部材２１へ向けて軸方向に付勢可能となるよう弾性力を蓄積した状態で介装しても良い。これにより、最もシンプルな構造で、無理なく付勢部材３２を設置することができる。 (Effect 5) The louver 5 positioned in the middle of the juxtaposed direction is arranged between the louvers 4 and 6 located on both sides of the juxtaposed direction and the louver 5 located in the middle of the juxtaposed direction. You may interpose in the state which accumulated the elastic force so that it could be urged | biased to the sliding resistance generating member 21 at an axial direction. Thereby, it is possible to install the biasing member 32 without difficulty with the simplest structure.
　（効果６）回転軸７ａの端部に抵抗増大部５１を設けて、抵抗増大部５１を摺動抵抗発生部材２１の受部５２で受けさせるようにしても良い。これにより、回転軸７ａの端部と摺動抵抗発生部材２１との間に、より大きな摺動抵抗を発生させることができる。また、抵抗増大部５１や受部５２の大きさや形状を工夫することによって、摺動抵抗を自在に設定・調整することができる。 (Effect 6) A resistance increasing portion 51 may be provided at the end of the rotating shaft 7a so that the resistance increasing portion 51 is received by the receiving portion 52 of the sliding resistance generating member 21. Thereby, a larger sliding resistance can be generated between the end of the rotating shaft 7 a and the sliding resistance generating member 21. Further, the sliding resistance can be freely set and adjusted by devising the size and shape of the resistance increasing portion 51 and the receiving portion 52.
　例えば、受部５２は、すり鉢状の凹部５５にして、抵抗増大部５１の外周部をすり鉢状の凹部５５で受けるようにすることができる。これにより、受部５２は、すり鉢状の凹部５５によって抵抗増大部５１を中心に寄せるセンターリング効果を有するものとなるので、回転軸７の軸ブレを防止することが可能になる。 For example, the receiving part 52 can be a mortar-shaped concave part 55 so that the outer peripheral part of the resistance increasing part 51 is received by the mortar-shaped concave part 55. As a result, the receiving portion 52 has a centering effect that brings the resistance increasing portion 51 to the center by the mortar-shaped concave portion 55, so that it is possible to prevent the shaft 7 from being shaken.
　また、例えば、受部５２は、平坦面にして、抵抗増大部５１の端面を受けるようにすることができる。これにより、受部５２は、抵抗増大部５１の端面を広い面積で受けて発生する摺動抵抗をより大きくすることができる。 Also, for example, the receiving part 52 can be made flat to receive the end face of the resistance increasing part 51. Thereby, the receiving part 52 can make the sliding resistance which generate | occur | produces by receiving the end surface of the resistance increasing part 51 in a wide area more.
