Description

本発明は、車室内空調装置の空気の吹出口として使用されるレジスタに関し、特に円筒型のリテーナ内に、略円形の空気吹出口を有するバレルが、上下左右自在に回動操作される丸型のレジスタに関する。 TECHNICAL FIELD The present invention relates to a register used as an air outlet for a vehicle interior air conditioner, and more particularly to a cylindrical retainer in which a barrel having a substantially circular air outlet is rotatably operated vertically and horizontally. regarding registers.

従来、円筒フレーム内に円形の空気吹出口を有する丸型レジスタとして、円筒フレーム内に円筒型のバレルが、空気吹出口の中心部を軸に、上下左右に傾動可能に支持された構造のレジスタが、下記特許文献１などで知られている。 Conventionally, as a round register having a circular air outlet in a cylindrical frame, a cylindrical barrel is supported in the cylindrical frame so that it can tilt vertically and horizontally around the center of the air outlet. is known from Patent Document 1 below.

このレジスタは、円筒型のバレルの内側に複数の固定フィンが放射状に設けられ、バレルの中心部に、ダンパ装置の操作ダイヤルが配置され、操作ダイヤルは、その中心軸を中心に回動操作可能に、固定フィンの中央部を支持する支持部内に支持される。操作ダイヤルの回動軸は、ケース内中央に支持された中央回動軸に、自在継手を介して連結され、自在継手は、支持部後部に配置され、中央回動軸の末端は、傘歯車を介してダンパプレートの歯部に噛合する構造である。 This register has a plurality of fixed fins radially arranged inside a cylindrical barrel, and an operation dial for a damper device is arranged in the center of the barrel, and the operation dial can be rotated around its central axis. Additionally, it is supported in a support that supports the central portion of the stationary fin.

しかし、この種の従来の丸型レジスタは、円形の空気吹出口の中央に位置する、操作ダイヤル、自在継手及びそれを支持する固定フィンの中央支持部が必然的に大形となり、相対的に空気吹出口の開口面積が減少する。このため、空気吹出口に十分な開口面積を確保するためには、レジスタの外径を大きくする必要があり、レジスタの小型化が難しい。 However, in this type of conventional round register, the operation dial, the universal joint, and the central support of the fixed fins supporting them, which are positioned in the center of the circular air outlet, are inevitably large, and relatively The opening area of the air outlet is reduced. Therefore, in order to secure a sufficient opening area for the air outlet, it is necessary to increase the outer diameter of the register, making it difficult to reduce the size of the register.

さらに、操作ダイヤル及び自在継手を保持する中央支持部の形状が大形となるため、送風時の空気抵抗が大きく、圧力損失が増大する。加えて、送風方向を変える際に、バレルを回動操作した場合、バレルが自在継手を支点に傾動し、レジスタ内の自在継手や中央支持部が正面に露出して、見栄えが悪くなり、レジスタのデザイン性が阻害される課題があった。 Furthermore, since the shape of the central support portion for holding the operation dial and the universal joint becomes large, the air resistance during air blowing is large, resulting in an increase in pressure loss. In addition, if the barrel is rotated to change the airflow direction, the barrel tilts about the universal joint as a fulcrum, exposing the universal joint and the central support in the register to the front, which makes the register look unattractive. There was a problem that the design of the product was hindered.

本発明は、上述の課題を解決するものであり、操作性が良く、送風時の圧力損失を低減でき、デザイン性に優れたレジスタを提供することを目的とする。 SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems, and to provide a register that is easy to operate, can reduce pressure loss during air blowing, and is excellent in design.

As shown in FIG. As shown in FIG. 7, a key 5a is provided on a part of the knob 5, and when the knob 5 is fitted into the boss portion 13a, the key 5a of the knob 5 fits into the key groove 13b provided in the boss portion 13a. The knob 5 is fitted in place. As shown in FIG. 6, the knob 5 is finally tightened and fixed to the boss portion 13a by a fixing screw 19 inserted from behind the boss portion 13a. An air outlet 9 opens in the front part of the barrel inner cylinder 12 of the barrel 1 .

上記構成のレジスタは、図８に示すように、バレル１のバレル外筒１１の外周面に、分割形成された保持フレーム２を組み付け、円弧状ガイド６を取り付け、キャップ１５をボス部材１６の二股脚部１６ａの先端に嵌着した状態で、リテーナ３の保持フレーム嵌入部３２内に、バレル１と保持フレーム２の組付体を嵌入し、その前部からベゼル４を嵌着して、組み立てられる。 As shown in FIG. 8, the above-configured register has a holding frame 2 which is divided and formed on the outer peripheral surface of a barrel outer cylinder 11 of a barrel 1, an arc-shaped guide 6 is attached, and a cap 15 is attached to a boss member 16. The assembled body of the barrel 1 and the holding frame 2 is fitted into the holding frame fitting portion 32 of the retainer 3 in a state where it is fitted to the tip of the leg portion 16a, and the bezel 4 is fitted from the front part thereof to assemble. be done.

このレジスタは、図１，２などに示すように、空気吹出口９内に、バレル１の固定フィン１３及びボス部１３ａ上のツマミ５が現れるのみであり、デザイン的に非常にシンプルで、レジスタの正面形状を含む車室内インストルメントパネルのデザインを、改善することができる。 As shown in FIGS. 1 and 2, this register has only a fixed fin 13 of the barrel 1 and a knob 5 on the boss portion 13a in the air outlet 9, and is very simple in design. The interior instrument panel design, including the frontal shape of the vehicle, can be improved.

また、バレル１のボス部１３ａを細く構成することができるため、バレル１の内径を大きくせずに、圧力損失を低減しつつ、必要な風量を確保することができる。このため、レジスタの外形つまりベゼル４及びリテーナ３の外径を、小さく細くすることができ、レジスタやインストルメントパネル全体の、デザインの自由度を向上させることができる。 In addition, since the boss portion 13a of the barrel 1 can be configured to be thin, the required air volume can be secured while reducing the pressure loss without increasing the inner diameter of the barrel 1 . Therefore, the outer shape of the register, that is, the outer diameter of the bezel 4 and the retainer 3 can be made small and thin, and the degree of freedom in designing the register and the instrument panel as a whole can be improved.

次に、上記構成のレジスタの使用態様を説明すると、レジスタは、車室内のインストルメントパネルなどに装着され、リテーナ３の後部に、空調装置の送風ダクトが接続される。 Next, the manner of use of the register having the above configuration will be described.

空調装置が作動して送風が行われると、バレル１がニュートラル状態で正面を向くとき、図１６，１７のように、正面に向けて真直ぐに送風される。ツマミ５を持ってバレル１を例えば下側に回動操作すると、図１８のように、バレル１は、支点Ｓ１を軸に下向きの回動力を受け、保持フレーム２内で、支点Ｓ１を中心に、斜め下向きに回動する。 When the air conditioner operates and air is blown, when the barrel 1 is in the neutral state and faces the front, the air is blown straight toward the front as shown in FIGS. When the knob 5 is held and the barrel 1 is rotated downward, for example, as shown in FIG. , rotates obliquely downward.

このとき、バレル外筒１１の外周面を保持する保持フレーム２は、そのゴム状弾性体により、バレル外筒１１を、弾性力を持って密に接して保持し回動させるため、ガタツキなくスムーズにバレル１の回動操作を行うことができる。バレル１は、図１８のように、ボス部材１６のキャップ１５が通風路３１の内壁に当接するまで回動し、停止する。 At this time, the holding frame 2, which holds the outer peripheral surface of the barrel outer cylinder 11, holds and rotates the barrel outer cylinder 11 in close contact with its elastic force due to its rubber-like elastic body. , the barrel 1 can be rotated. The barrel 1 rotates until the cap 15 of the boss member 16 comes into contact with the inner wall of the ventilation passage 31 as shown in FIG. 18, and then stops.

またこのとき、バレル１の回動は、そのボス部材１６がボス荷重付与部材１８を介して円弧状ガイド６に摺接して行われ、バレル１は適度の操作荷重でスムーズに回動操作される。また、円弧状ガイド６と保持フレーム２の内球面部２３のガイドによっても、回動操作はガタツキなくスムーズに行われる。この操作により、送風方向が斜め下方に向けられ、送風は、リテーナ３の通風路３１からバレル１内に入り、空気吹出口９から斜め下側に向けて送風される。 At this time, the barrel 1 is rotated while the boss member 16 is in sliding contact with the arc-shaped guide 6 via the boss load imparting member 18, and the barrel 1 is smoothly rotated with an appropriate operating load. . Further, the circular arc-shaped guide 6 and the guide of the inner spherical surface portion 23 of the holding frame 2 also allow the rotating operation to be performed smoothly without rattling. By this operation, the air blow direction is directed obliquely downward, and the air enters the barrel 1 through the ventilation passage 31 of the retainer 3 and is blown obliquely downward from the air outlet 9 .

送風方向を斜め上側に調整する場合も、同様であり、バレル１を上側に回動操作すると、バレル１の背面側は、図２０のように、下側に回動する。このとき、バレル１のボス部材１６は、軸部荷重付与部材２４を円弧状ガイド６に摺接させながら、下側に回動し、バレル１の空気吹出口９は斜め上側に向けられる。このようなバレル１の回動操作もスムーズに行うことができる。 The same is true when adjusting the airflow direction obliquely upward. When the barrel 1 is rotated upward, the rear side of the barrel 1 rotates downward as shown in FIG. At this time, the boss member 16 of the barrel 1 rotates downward while the axial load imparting member 24 is brought into sliding contact with the arc-shaped guide 6, and the air outlet 9 of the barrel 1 is directed obliquely upward. Such rotating operation of the barrel 1 can also be performed smoothly.

一方、ツマミ５を持ってバレル１を例えば右側に回動操作すると、図１９のように、バレル１は、支点Ｓ１を中心に右向きの回動力を受け、保持フレーム２内で、支点Ｓ１を中心に、斜め右向きに円弧状ガイド６とともに回動する。バレル１の回動は、図１９のように、ボス部材１６のキャップ１５が通風路３１の内壁に当接するまで回動し、停止する。 On the other hand, when the knob 5 is held and the barrel 1 is rotated, for example, to the right, the barrel 1 receives a rightward rotation force about the fulcrum S1 as shown in FIG. Then, it rotates obliquely to the right together with the arcuate guide 6 . As shown in FIG. 19, the barrel 1 rotates until the cap 15 of the boss member 16 comes into contact with the inner wall of the ventilation passage 31 and then stops.

このとき、ボス部材１６内を通る円弧状ガイド６は、その両端の回動軸部６１を中心に、図２１のように回動し、且つ軸保持部２５内で軸部荷重付与部材２４に回動軸部６１を摺接させて回動する。これにより、バレル１の回動には適度な操作荷重が付与され、スムーズに回動操作することができる。また、バレル１のバレル外筒１１は、ゴム状弾性体の保持フレーム２の内球面部２３内で保持されて回動するため、バレル１はガタツキなくスムーズに回動することができる。送風方向を左側に調整する場合も、同様であり、バレル１の回動操作をスムーズに行うことができる。 At this time, the arcuate guide 6 passing through the boss member 16 rotates about the rotation shafts 61 at both ends thereof as shown in FIG. It rotates while sliding on the rotating shaft portion 61 . As a result, an appropriate operating load is applied to the rotation of the barrel 1, and the rotation can be performed smoothly. Further, since the barrel outer cylinder 11 of the barrel 1 rotates while being held within the inner spherical surface portion 23 of the holding frame 2 made of a rubber-like elastic material, the barrel 1 can rotate smoothly without rattling. The same is true when adjusting the blowing direction to the left, and the rotation operation of the barrel 1 can be performed smoothly.

さらに、バレル１のバレル外筒１１の外周面を保持する保持フレーム２は、そのゴム状弾性体により、バレル外筒１１に、弾性力を持って密に接し、保持した状態で、バレル１が回動する。このため、バレル１と保持フレーム２間に、隙間は生じず、隙間によって生じやすい、真直ぐに進む漏れ空気流を生じさせない。このため、漏れ空気流によって乱されることなく、バレル１の向く方向に調整された空気流を、良好に送風することができる。 Further, the holding frame 2 that holds the outer peripheral surface of the barrel outer cylinder 11 of the barrel 1 is in close contact with the barrel outer cylinder 11 with elastic force due to its rubber-like elastic body, and the barrel 1 is held in a state of being held. Rotate. As a result, no gap is formed between the barrel 1 and the holding frame 2, and straight-forward leakage airflow, which tends to be caused by the gap, is not generated. Therefore, the airflow adjusted in the direction in which the barrel 1 is directed can be sent satisfactorily without being disturbed by the leakage airflow.

図２２～図３０は、第２実施形態のレジスタを示している。このレジスタでは、保持フレーム４０の構造が変更され、円弧状ガイド７が変更され、ボス部材５１、軸部荷重付与部材４４、及びボス荷重付与部材５８が変更されている。他の部材は、上記実施形態と同様であり、同じ部材については、図２２～図３０に同一の符号を付して説明を省略する。 22-30 show the register of the second embodiment. In this register, the structure of the holding frame 40 is changed, the arc-shaped guide 7 is changed, and the boss member 51, the shank load applying member 44, and the boss load applying member 58 are changed.

As shown in FIG. 22B, fitting recesses 4a are provided in the upper and lower portions of the fitting portion of the bezel 4, and the rotating shaft portion 71 of the arc-shaped guide 7 of the holding frame 40 is inserted into the fitting recesses 4a. ing.

図２２に示すように、リテーナ３内にバレル１が組み付けられるとき、バレル１の保持フレーム４０の上下部に設けた回動軸部７１が、その周囲の枠部４６とともにリテーナ３の嵌入凹部３５内に挿入される。このとき、下部の嵌入凹部３５内に位置する回動軸部７１の円筒部７２に、円孔４４ａを有する軸部荷重付与部材４４が嵌合される（図２４、図２８）。つまり、軸部荷重付与部材４４の円孔４４ａに、円弧状ガイド７の回動軸部７１の円筒部７２が嵌入され、図２２Ａのように、軸部荷重付与部材４４は嵌入凹部３５内に組み付けられる。これにより、バレル１の回動操作時、円弧状ガイド７が回動軸部７１を中心に回動したとき、軸部荷重付与部材４４と円筒部７２の摩擦抵抗により、適度な操作荷重が付与される。軸部荷重付与部材４４には、例えばシリコーンゴムなどのゴム状弾性体により形成される、汎用の部材を利用することができる。 As shown in FIG. 22 , when the barrel 1 is assembled in the retainer 3 , the rotation shafts 71 provided on the upper and lower portions of the holding frame 40 of the barrel 1 move together with the surrounding frame 46 into the fitting recess 35 of the retainer 3 . inserted within. At this time, the shaft portion load imparting member 44 having the circular hole 44a is fitted to the cylindrical portion 72 of the rotating shaft portion 71 located in the lower fitting recess 35 (FIGS. 24 and 28). That is, the cylindrical portion 72 of the rotary shaft portion 71 of the arcuate guide 7 is fitted into the circular hole 44a of the shaft load applying member 44, and the shaft load applying member 44 is inserted into the fitting recess 35 as shown in FIG. 22A. can be assembled. As a result, when the arc-shaped guide 7 rotates around the rotation shaft portion 71 during the rotation operation of the barrel 1, an appropriate operation load is applied due to the frictional resistance between the shaft portion load applying member 44 and the cylindrical portion 72. be done. A general-purpose member formed of a rubber-like elastic body such as silicone rubber can be used for the shaft portion load imparting member 44 .

バレル１は、上記と同様、放射状の固定フィン１３を内側に設けたバレル内筒１２の外側に、バレル外筒１１を嵌合して構成される。バレル内筒１２内に、３個の固定フィン１３が１２０°の間隔で放射状に設けられ、固定フィン１３の中心部に、円筒状のボス部１３ａが形成される。固定フィン１３とボス部１３ａはバレル１の背面側後部に突き出すように形成され、固定フィン１３は、その側面形状がバレル内筒１２の近傍で下流側に延び、ボス部側で上流側に延びるように傾斜して形成される。 The barrel 1 is constructed by fitting the barrel outer cylinder 11 to the outside of the barrel inner cylinder 12 provided with the radial fixing fins 13 on the inside thereof, in the same manner as described above. Three fixed fins 13 are radially provided in the barrel inner cylinder 12 at an interval of 120°, and a cylindrical boss portion 13a is formed at the center of the fixed fins 13 . The fixed fin 13 and the boss portion 13a are formed so as to protrude from the rear side of the rear side of the barrel 1, and the side surface of the fixed fin 13 extends downstream in the vicinity of the barrel inner cylinder 12 and extends upstream on the boss portion side. It is formed so that it is slanted.

背面側に突出したボス部１３ａの後端部に、ボス部材５１が嵌着され、さらにボス部材５１の後部にキャップ１５が嵌着される。キャップ１５は、円弧状ガイド６がボス部材５１の摺動部つまり二股脚部５２内から外れないように保持する機能を有し、通常時、円弧状ガイド７とは非接触状態で、二股脚部５２に嵌着される。 A boss member 51 is fitted to the rear end portion of the boss portion 13 a protruding to the rear side, and a cap 15 is fitted to the rear portion of the boss member 51 . The cap 15 has a function to hold the arc-shaped guide 6 so as not to come off from the sliding portion of the boss member 51, that is, the bifurcated leg portion 52. Normally, the cap 15 is in a non-contact state with the arc-shaped guide 7, and the bifurcated leg is held. The part 52 is fitted.

図２４に示すように、円筒形のバレル内筒１２には、後部にフランジが設けられるとともに、外周面にガイドリブ１２ａと係止部１２ｂが設けられる。また、バレル内筒１２の内周に、下流側に向けて開くように傾斜する傾斜内周面が設けられ、送風時の空気抵抗を低減している。 As shown in FIG. 24, the cylindrical barrel inner cylinder 12 is provided with a flange at its rear portion, and guide ribs 12a and locking portions 12b on its outer peripheral surface. In addition, the inner circumference of the barrel inner cylinder 12 is provided with an inclined inner peripheral surface that is inclined so as to open toward the downstream side, thereby reducing air resistance during air blowing.

バレル外筒１１は、バレル内筒１２の外側に外嵌される内径を有し、バレル外筒１１をバレル内筒１２の外側に嵌着したとき、定位置で係止されるように、ガイドリブ１１ｂが、バレル内筒１２のガイドリブ１２ａに対応して設けられ、係止部１１ｃがバレル内筒１２の係止部１２ｂに係止可能に設けられる。バレル外筒１１の外周面は、図２３、２９に示すように、支点Ｓ１の中心とする球の球面部１１ａとして形成され、球面部１１ａは上記保持フレーム４０の内球面部４３と略同一の球面とされる。 The barrel outer cylinder 11 has an inner diameter that fits on the outside of the barrel inner cylinder 12, and guide ribs are provided so that when the barrel outer cylinder 11 is fitted on the outside of the barrel inner cylinder 12, it is locked at a fixed position. 11b are provided corresponding to the guide ribs 12a of the barrel inner tube 12, and locking portions 11c are provided so as to be locked to the locking portions 12b of the barrel inner tube 12. As shown in FIG. As shown in FIGS. 23 and 29, the outer peripheral surface of the barrel outer cylinder 11 is formed as a spherical surface portion 11a centered on the fulcrum S1. It is assumed to be spherical.

上記構成のレジスタは、図２３に示すように、バレル１のバレル外筒１１の外周面に、分割形成された保持フレーム４０を組み付け、円弧状ガイド７を取り付け、キャップ１５をボス部材５１の二股脚部５２の先端に嵌着した状態で、リテーナ３の保持フレーム嵌入部３２内に、バレル１と保持フレーム４０の組付体を嵌入し、その前部からベゼル４を嵌着して、組み立てられる。 As shown in FIG. 23, the above-configured register has a holding frame 40 that is divided and formed on the outer peripheral surface of the barrel outer cylinder 11 of the barrel 1, an arc-shaped guide 7 is attached, and a cap 15 is attached to the boss member 51. The assembled body of the barrel 1 and the holding frame 40 is fitted into the holding frame fitting portion 32 of the retainer 3 in a state where it is fitted to the tip of the leg portion 52, and the bezel 4 is fitted from the front part thereof for assembly. be done.

次に、上記構成のレジスタの使用態様を説明する。空調装置が作動してレジスタに送風を行うと、図２８，２９のように、バレル１がニュートラル状態で正面を向くとき、正面に向けて真直ぐに送風される。ツマミ５を持ってバレル１を例えば右側に回動操作すると、図３０のように、バレル１は、支点Ｓ１を軸に右向きの回動力を受け、保持フレーム２内で、支点Ｓ１を中心に、右向きに回動する。 Next, the manner of using the register having the above configuration will be described. When the air conditioner operates and blows air to the register, as shown in FIGS. 28 and 29, when the barrel 1 is in the neutral state and faces the front, the air is blown straight toward the front. When the knob 5 is held and the barrel 1 is turned, for example, to the right, as shown in FIG. Rotate to the right.

このとき、バレル外筒１１の外周面を保持する保持フレーム４０は、そのゴム状弾性体により、バレル外筒１１を、弾性力を持って密に接して保持し回動させるため、ガタツキなくスムーズにバレル１の回動操作を行うことができる。バレル１は、ボス部材５１のキャップ１５が通風路３１の内壁に当接するまで回動し、停止する。 At this time, the holding frame 40, which holds the outer peripheral surface of the barrel outer cylinder 11, holds and rotates the barrel outer cylinder 11 in close contact with its elastic force due to its rubber-like elastic body, so that the barrel outer cylinder 11 can be rotated smoothly without rattling. , the barrel 1 can be rotated. The barrel 1 rotates until the cap 15 of the boss member 51 contacts the inner wall of the ventilation passage 31 and stops.

またこのとき、バレル１の回動は、そのボス部材５１がボス荷重付与部材５８を介して円弧状ガイド７に摺接して行われ、バレル１は適度の操作荷重でスムーズに回動操作される。また、円弧状ガイド７と保持フレーム４０の内球面部４３のガイドによっても、回動操作はガタツキなくスムーズに行われる。この操作により、送風方向が斜め右方向に向けられ、送風は、リテーナ３の通風路３１からバレル１内に入り、空気吹出口９から斜め右側に向けて送風される。 At this time, the barrel 1 is rotated while the boss member 51 is in sliding contact with the arc-shaped guide 7 via the boss load imparting member 58, and the barrel 1 is smoothly rotated with an appropriate operating load. . In addition, the circular arc guide 7 and the guide of the inner spherical surface portion 43 of the holding frame 40 also allow the rotating operation to be performed smoothly without rattling. By this operation, the air blow direction is directed obliquely to the right, and the air enters the barrel 1 through the ventilation passage 31 of the retainer 3 and is blown obliquely to the right from the air outlet 9 .

送風方向を斜め上側に調整する場合も、同様であり、バレル１を上側に回動操作すると、バレル１の背面側は、下側に回動する。このとき、バレル１のボス部材５１は、軸部荷重付与部材４４を円弧状ガイド７に摺接させながら、下側に回動し、バレル１の空気吹出口９は斜め上側に向けられる。このようなバレル１の回動操作もスムーズに行うことができる。 The same is true when adjusting the air blowing direction obliquely upward. When the barrel 1 is rotated upward, the rear side of the barrel 1 rotates downward. At this time, the boss member 51 of the barrel 1 rotates downward while the shaft portion load imparting member 44 is brought into sliding contact with the arc-shaped guide 7, and the air outlet 9 of the barrel 1 is directed obliquely upward. Such rotating operation of the barrel 1 can also be performed smoothly.

一方、ツマミ５を持ってバレル１を例えば右側に回動操作すると、バレル１は、支点Ｓ１を中心に右向きの回動力を受け、保持フレーム４０内で、支点Ｓ１を中心に、斜め右向きに円弧状ガイド７とともに回動する。バレル１の回動は、ボス部材５１のキャップ１５が通風路３１の内壁に当接するまで回動し、停止する。 On the other hand, when the knob 5 is held and the barrel 1 is rotated, for example, to the right, the barrel 1 receives a rightward turning force about the fulcrum S1, and rotates diagonally to the right in the holding frame 40 about the fulcrum S1. It rotates together with the arcuate guide 7 . The barrel 1 rotates until the cap 15 of the boss member 51 comes into contact with the inner wall of the ventilation passage 31 and then stops.

このとき、ボス部材５１内を通る円弧状ガイド７は、その両端の回動軸部７１を中心に回動し、且つ軸保持部４５内で軸部荷重付与部材４４に回動軸部７１を摺接させて回動する。これにより、バレル１の回動には適度な操作荷重が付与され、スムーズに回動操作することができる。また、バレル１のバレル外筒１１は、ゴム状弾性体の保持フレーム４０の内球面部４３内で保持されて回動するため、バレル１はガタツキなくスムーズに回動することができる。送風方向を左側に調整する場合も、同様であり、バレル１の回動操作をスムーズに行うことができる。 At this time, the arc-shaped guide 7 passing through the inside of the boss member 51 rotates around the rotation shaft portions 71 at both ends thereof, and the rotation shaft portions 71 are attached to the shaft portion load applying member 44 within the shaft holding portion 45 . Sliding and rotating. As a result, an appropriate operating load is applied to the rotation of the barrel 1, and the rotation can be performed smoothly. Further, since the barrel outer cylinder 11 of the barrel 1 rotates while being held within the inner spherical surface portion 43 of the holding frame 40 made of a rubber-like elastic material, the barrel 1 can rotate smoothly without rattling. The same is true when adjusting the blowing direction to the left, and the rotation operation of the barrel 1 can be performed smoothly.

さらに、バレル１のバレル外筒１１の外周面を保持する保持フレーム４０は、そのゴム状弾性体により、バレル外筒１１に、弾性力を持って密に接し、保持した状態で、バレル１が回動する。このため、バレル１と保持フレーム４０間に、隙間は生じず、隙間によって生じやすい、真直ぐに進む漏れ空気流を生じさせない。このため、漏れ空気流によって乱されることなく、バレル１の向く方向に調整された空気流を、良好に送風することができる。 Furthermore, the holding frame 40 that holds the outer peripheral surface of the barrel outer cylinder 11 of the barrel 1 is in close contact with the barrel outer cylinder 11 with elastic force due to its rubber-like elastic body, and the barrel 1 is held in a state of being held. Rotate. As a result, no gap is formed between the barrel 1 and the holding frame 40, and straight-forward leakage airflow, which tends to be caused by the gap, is not generated. Therefore, the airflow adjusted in the direction in which the barrel 1 is directed can be sent satisfactorily without being disturbed by the leakage airflow.
