Description

本発明は、自動車の車内等の換気や空調装置の空気吹出口に使用されるレジスタに関し、特に前フィン上に、操作ノブを摺動可能に外嵌したレジスタの操作ノブ装置に関する。 The present invention relates to a register used for ventilation of an automobile, etc., and an air outlet of an air conditioner, and particularly to an operation knob device of a register in which an operation knob is slidably fitted on a front fin.

従来、車両用のレジスタとして、通風路を形成するベゼル内に、前可動ルーバと後可動ルーバを前後して直交方向に配設し、前方に位置する前可動ルーバの前フィン上に、操作ノブを、フィンの長手方向に摺動可能に取り付けた構造のレジスタが、下記特許文献１などにより知られている。 Conventionally, as a register for a vehicle, a front movable louver and a rear movable louver are arranged in the front and rear orthogonal directions in a bezel forming a ventilation path, and an operation knob is placed on the front fin of the front movable louver located in the front. A register having a structure in which a fin is slidably attached in the longitudinal direction is known from Patent Document 1 and the like below.

この操作ノブは、前可動ルーバの前フィン上に、その長手方向に摺動可能に外嵌され、操作ノブの上流側の後端部に、ラック状或いは二股状の係合部が設けられ、その係合部が後方上流側に位置する後可動ルーバに係合する。風の向きを左右に調整する場合、操作ノブを前可動ルーバの前フィン上で左又は右に摺動させ、後可動ルーバの向きを左右に変え、送風方向を左右に調整する。 This operation knob is slidably fitted on the front fin of the front movable louver in the longitudinal direction thereof, and a rack-shaped or bifurcated engaging portion is provided at the rear end portion on the upstream side of the operation knob. The engaging portion engages with the rear movable louver located on the rear upstream side. When adjusting the direction of the wind to the left or right, slide the operation knob to the left or right on the front fin of the front movable louver, change the direction of the rear movable louver to the left or right, and adjust the blowing direction to the left or right.

特開２０１０－１１５９７２号公報Japanese Unexamined Patent Publication No. 2010-115972 米国特許第１０７９２９７４号明細書U.S. Pat. No. 10,792,974

また、レジスタにおいて、一体成形された操作ノブを、前フィンの下面にスライド可能に嵌合させた構造の操作ノブ装置が、上記特許文献２で提案されている。 Further, Patent Document 2 proposes an operation knob device having a structure in which an integrally molded operation knob is slidably fitted to the lower surface of a front fin in a register.

このレジスタの操作ノブ装置は、前フィンの下面に、深い摺動溝がフィンの長手方向に沿って形成され、操作ノブの上面に係合凸部が突設され、操作ノブが、前フィンの下面に係合凸部を摺動溝に嵌合させて取り付けられる。 In the operation knob device of this register, a deep sliding groove is formed on the lower surface of the front fin along the longitudinal direction of the fin, an engaging protrusion is projected on the upper surface of the operation knob, and the operation knob is the front fin. It is attached to the lower surface by fitting the engaging protrusion into the sliding groove.

しかし、この操作ノブ装置は、前フィンの下面に操作ノブが取り付けられ、操作ノブを比較的薄く構成することができるものの、前フィンの下面に深い溝が斜めに形成されるため、前フィンの長手方向の撓み強度が低下する。 However, in this operation knob device, although the operation knob is attached to the lower surface of the front fin and the operation knob can be made relatively thin, a deep groove is formed diagonally on the lower surface of the front fin, so that the front fin has a relatively thin structure. The bending strength in the longitudinal direction decreases.

さらに、操作ノブを前フィンに嵌合させる場合、前フィンの端部まで達する摺動溝に、操作ノブの係合凸部を端部から嵌め込み、中央位置まで摺動させて嵌合させる。このため、操作ノブの前フィンへの取付作業工数が増大し、操作ノブを通常摺動させない部分にも、摺動溝を付ける必要があり、これにより、前フィンの長手方向の撓み強度が低下し、前フィンの外観も悪化する課題があった。 Further, when the operation knob is fitted to the front fin, the engaging convex portion of the operation knob is fitted from the end portion into the sliding groove reaching the end portion of the front fin, and is slid to the center position to be fitted. For this reason, the man-hours for attaching the operation knob to the front fin increase, and it is necessary to provide a sliding groove even in the portion where the operation knob is not normally slid, which reduces the bending strength of the front fin in the longitudinal direction. However, there was a problem that the appearance of the front fins also deteriorated.

本発明は、上記の点に鑑みてなされたもので、前フィンの撓み強度を高く保持しつつ、操作ノブの厚さを薄くすることができ、見栄えなどを良くすることができるレジスタの操作ノブ装置を提供することを目的とする。 The present invention has been made in view of the above points, and it is possible to reduce the thickness of the operation knob while maintaining a high bending strength of the front fins, and to improve the appearance of the register operation knob. The purpose is to provide the device.

上記目的を達成するために、本発明のレジスタの操作ノブ装置は、
レジスタの空気吹出口の内側に、回動可能に前フィンが軸支され、操作ノブが該前フィンの長手方向に、摺動可能に外嵌されたレジスタの操作ノブ装置において、

レジスタの組み付け時、後可動ルーバ４は、図４に示すように、上軸受部４２と下軸受部４３間に複数の後フィン４０を並設して取り付けた状態で、リテーナ２の通風路９内に挿入され、組み付けられる。 When assembling the register, as shown in FIG. 4, the rear movable louver 4 has a plurality of rear fins 40 arranged side by side between the upper bearing portion 42 and the lower bearing portion 43, and the rear fins 4 are attached to the ventilation passage 9 of the retainer 2. It is inserted inside and assembled.

前可動ルーバ３は、図４に示す如く、複数（例えば３枚）の前フィン３０，３６，３７を、水平横方向に配置し、各前フィン３０，３６，３７を上下に一定の間隔をおいて並設して構成される。各前フィン３０，３６，３７は、ベゼル５の内側で、リテーナ２の前部の左右側壁に設けた軸受部３ａにより軸支される。両側の軸受部３ａには、各々３個の軸孔が一定の間隔で穿設され、軸受部３ａは、ベゼル５の空気吹出口８の直ぐ内側に配設され、左右側壁の内側に対向して取り付けられる。 As shown in FIG. 4, in the front movable louver 3, a plurality of (for example, three) front fins 30, 36, 37 are arranged in the horizontal horizontal direction, and the front fins 30, 36, 37 are vertically spaced at regular intervals. It is configured by arranging them side by side. The front fins 30, 36, and 37 are pivotally supported inside the bezel 5 by bearing portions 3a provided on the left and right side walls of the front portion of the retainer 2. Three shaft holes are bored in the bearing portions 3a on both sides at regular intervals, and the bearing portions 3a are arranged immediately inside the air outlet 8 of the bezel 5 and face the inside of the left and right side walls. Can be attached.

前可動ルーバ３の３枚の前フィン３０，３６，３７は、両側の軸受部３ａ間で支持されるように、前フィン３０等の両端部に突設した支軸３０ａが、両側の軸受部３ａの各軸孔に嵌入され、軸支される。中央の前フィン３０には、操作ノブ１が前フィン３０の長手方向に摺動可能に外嵌される。なお、前可動ルーバ３の３枚の前フィン３０，３６，３７は、一枚のみの前フィンとすることもでき、４枚以上の前フィンとしてもよい。 The three front fins 30, 36, 37 of the front movable louver 3 have support shafts 30a projecting from both ends of the front fins 30 and the like so as to be supported between the bearing portions 3a on both sides. It is fitted into each shaft hole of 3a and is supported by a shaft. An operation knob 1 is slidably fitted to the central front fin 30 in the longitudinal direction of the front fin 30. The three front fins 30, 36, 37 of the front movable louver 3 may be only one front fin, or may be four or more front fins.

また、図８に示すように、中央の前フィン３０の一端にガイドピン３０ｃが、一方の支軸３０ａに近傍に突設され、ガイドピン３０ｃは軸受部３ａに形成されたガイド溝に係合し、前フィン３０の回動範囲をガイドする。さらに、各前フィン３０の一端部に連結軸３０ｂが突設され、１本のリンクバー３ｂがそれらの連結軸３０ｂに連結される。これにより、中央の前フィン３０に外嵌された操作ノブ１を持って前フィン３０を上下に回動操作すると、前可動ルーバ３の各前フィン３０は両側の支軸３０ａを軸に、所定の角度範囲内で、上または下に回動する。 Further, as shown in FIG. 8, a guide pin 30c is projected near one of the support shafts 30a at one end of the central front fin 30, and the guide pin 30c engages with the guide groove formed in the bearing portion 3a. Then, the rotation range of the front fin 30 is guided. Further, a connecting shaft 30b is projected from one end of each front fin 30, and one link bar 3b is connected to the connecting shaft 30b. As a result, when the front fin 30 is rotated up and down by holding the operation knob 1 fitted to the central front fin 30, each front fin 30 of the front movable louver 3 is predetermined with the support shafts 30a on both sides as the axis. Rotate up or down within the angle range of.

The front fin 30 and the operation knob 1 are slidably fitted without a gap.

上記のように、前フィン３０のガイド凸部３２の両面に、３本のリブ３８がノブ本体１０のガイド凹部１２内と接触可能に設けられ、ガイド凸部３２の先端は、ノブ本体１０のガイド凹部１２の内面と線接触する。これにより、操作ノブ１の摺動操作時、ガイド凸部３２とノブ本体１０間に生じる摩擦抵抗を低減する。 As described above, three ribs 38 are provided on both sides of the guide convex portion 32 of the front fin 30 so as to be in contact with the inside of the guide concave portion 12 of the knob main body 10, and the tip of the guide convex portion 32 is the tip of the knob main body 10. Line contact with the inner surface of the guide recess 12. As a result, the frictional resistance generated between the guide convex portion 32 and the knob main body 10 during the sliding operation of the operation knob 1 is reduced.

また、前フィン３０の切欠凹部３１に隣接した前フィン３０の上面側に、板状凹部３３が一段低く設けられ、この板状凹部３３を上から覆って摺接する板状部２３が図１３のように、ノブ後部１３に設けられる。図１５に示すように、ノブ本体１０の後部に、ノブ後部１３を嵌着した状態で、ノブ後部１３の板状部２３が前フィン３０の板状凹部３３を覆い、前フィン３０上に操作ノブ１を摺動可能に保持する。 Further, a plate-shaped recess 33 is provided one step lower on the upper surface side of the front fin 30 adjacent to the notch recess 31 of the front fin 30, and the plate-shaped portion 23 that covers the plate-shaped recess 33 from above and slides into contact with the plate-shaped recess 33 is shown in FIG. As described above, the knob rear portion 13 is provided. As shown in FIG. 15, with the knob rear portion 13 fitted to the rear portion of the knob body 10, the plate-shaped portion 23 of the knob rear portion 13 covers the plate-shaped recess 33 of the front fin 30 and is operated on the front fin 30. Holds the knob 1 slidably.

図１２に示すように、ノブ本体１０内の後部に断面コ字状の嵌合部２０が設けられ、図１３に示すように、ノブ後部１３内にも断面コ字状の嵌合部２１が設けられる。ノブ本体１０とノブ後部１３は、相互に設けた断面コ字状の嵌合部２０，２１の嵌合により前後方向に移動して嵌合するとともに、ノブ本体１０に設けた係止爪１６とノブ後部１３に設けた係止部１５との係合により係止される。 As shown in FIG. 12, a fitting portion 20 having a U-shaped cross section is provided in the rear portion of the knob main body 10, and as shown in FIG. 13, a fitting portion 21 having a U-shaped cross section is also provided in the rear portion 13 of the knob. It will be provided. The knob main body 10 and the knob rear portion 13 move in the front-rear direction due to the fitting of the fitting portions 20 and 21 having a U-shaped cross section provided with each other, and are fitted with the locking claw 16 provided on the knob main body 10. It is locked by engaging with the locking portion 15 provided on the rear portion 13 of the knob.

これにより、組み付け時には、図１５に示すように、前フィン３０の前部から下面を覆うようにノブ本体１０を配置した状態で、ノブ後部１３をノブ本体１０の後方から嵌合部２０と嵌合部２１とを嵌め込み、係止部１５を係止爪１６に係止させて、ノブ本体１０とノブ後部１３とを簡単に且つ確実に組み付けることができる。なお、上記とは逆に、係止部１５をノブ本体１０の後端部に設け、係止爪１６をノブ後部１３内に設ける構造としてもよい。 As a result, at the time of assembly, as shown in FIG. 15, the knob main body 10 is arranged so as to cover the lower surface from the front portion of the front fin 30, and the knob rear portion 13 is fitted to the fitting portion 20 from the rear of the knob main body 10. The knob main body 10 and the knob rear portion 13 can be easily and surely assembled by fitting the joint portion 21 and locking the locking portion 15 to the locking claw 16. Contrary to the above, the locking portion 15 may be provided at the rear end portion of the knob body 10, and the locking claw 16 may be provided inside the knob rear portion 13.

図１～図４に示すように、ベゼル５の前面左側にダンパノブ用開口部が形成され、そこにダンパノブ６が、露出して配置され、上下に回動操作可能に軸支される。リテーナ２は、上記のように、略矩形のダクト状に形成され、内部に通風路９が形成される。通風路９内後部の両側側壁にダンパ用の軸孔が設けられ、一方の軸孔にダンパプレート７の端部に設けた支軸７ｃ（図７）が嵌入され、他方の軸孔には、外側から回動軸７ａが嵌挿され、通風路９の内側で、回動軸７ａの係止部がダンパプレート７の他方の端部に係止される。 As shown in FIGS. 1 to 4, a damper knob opening is formed on the left side of the front surface of the bezel 5, and the damper knob 6 is exposed and arranged there, and is pivotally supported so as to be rotatable up and down. As described above, the retainer 2 is formed in a substantially rectangular duct shape, and a ventilation passage 9 is formed inside. Shaft holes for dampers are provided on both side walls of the rear portion of the ventilation passage 9, and a support shaft 7c (FIG. 7) provided at the end of the damper plate 7 is fitted into one shaft hole, and the other shaft hole is fitted with a shaft hole. The rotation shaft 7a is fitted and inserted from the outside, and the locking portion of the rotation shaft 7a is locked to the other end of the damper plate 7 inside the ventilation passage 9.

図２に示す如く、ダンパプレート７の一方の回動軸７ａには、ダンパアーム７ｂが連結され、ダンパアーム７ｂは、リンクレバー６ａを介して、ダンパノブ６の端部にリンクされる。これにより、ダンパノブ６を上又は下に回動操作したとき、ダンパプレート７が回動し、通風路９が開閉される。 As shown in FIG. 2, a damper arm 7b is connected to one rotation shaft 7a of the damper plate 7, and the damper arm 7b is linked to an end portion of the damper knob 6 via a link lever 6a. As a result, when the damper knob 6 is rotated up or down, the damper plate 7 rotates and the ventilation passage 9 is opened and closed.

次に、操作ノブ１の組み立てを説明すると、前フィン３０上に操作ノブ１を組み付ける場合、先ず、前フィン３０の取付部３５に、荷重付与部材１７を取り付け、その状態で、図１４に示す如く、前フィン３０のガイド凸部３２をノブ本体１０のガイド凹部１２内に挿入しながら、ノブ本体１０内のカバー凹部１４内に、押し込むように挿入する。 Next, to explain the assembly of the operation knob 1, when assembling the operation knob 1 on the front fin 30, first, the load applying member 17 is attached to the attachment portion 35 of the front fin 30, and in that state, it is shown in FIG. As described above, the guide convex portion 32 of the front fin 30 is inserted into the guide concave portion 12 of the knob main body 10 while being pushed into the cover concave portion 14 in the knob main body 10.

このとき、前フィン３０の前端部の半円柱部３４は、ノブ本体１０の前部１１の湾曲凹面部１１ａ内を滑るように図１４の下図まで進入し、簡単に組み付けられる。次に、ノブ後部１３の軸支部２２に、二股係合部２５の枢軸２５ａを嵌入し、この状態のノブ後部１３を、ノブ本体１０の後部に嵌め込む。このとき、図１５に示すように、嵌合部２０と嵌合部２１が嵌合するとともに、係止爪１６が係止部１５に係止され、組み付けは完了する。 At this time, the semi-cylindrical portion 34 at the front end portion of the front fin 30 slides in the curved concave surface portion 11a of the front portion 11 of the knob main body 10 and enters to the lower figure of FIG. 14, and is easily assembled. Next, the pivot 25a of the bifurcated engaging portion 25 is fitted into the shaft support portion 22 of the knob rear portion 13, and the knob rear portion 13 in this state is fitted into the rear portion of the knob main body 10. At this time, as shown in FIG. 15, the fitting portion 20 and the fitting portion 21 are fitted, and the locking claw 16 is locked to the locking portion 15, and the assembly is completed.

この状態で、図１０に示すように、操作ノブ１の前部１１は、ガイド凸部３２によって前フィン３０の前部に保持され、操作ノブ１のノブ後部１３は、その板状部２３が前フィン３０の板状凹部３３上を覆い、前フィン３０の後部に保持される。さらに、取付部３５内の荷重付与部材１７はノブ本体１０の摺接部１８と接触し、操作ノブ１は、その前部１１のガイド凹部１２内に、前フィン３０側のガイド凸部３２が摺動可能に収容される。 In this state, as shown in FIG. 10, the front portion 11 of the operation knob 1 is held by the guide convex portion 32 at the front portion of the front fin 30, and the knob rear portion 13 of the operation knob 1 has a plate-shaped portion 23 thereof. It covers the plate-shaped recess 33 of the front fin 30 and is held at the rear portion of the front fin 30. Further, the load applying member 17 in the mounting portion 35 comes into contact with the sliding contact portion 18 of the knob body 10, and the operation knob 1 has a guide convex portion 32 on the front fin 30 side in the guide concave portion 12 of the front portion 11 thereof. It is slidably housed.

これにより、操作ノブ１は、前フィン３０上で、摺動可能に保持され、操作ノブ１を左右にスライド操作すると、ノブ本体１０の摺接部１８が荷重付与部材１７と接触しながら摺動するとともに、ガイド凸部３２は、その先端の半円柱部３２ａ及びその上下面のリブ３８（図１１）がガイド凹部１２内で接触し、ガイドされながら摺動する。これにより、操作ノブ１は、前フィン３０を上下に振る際や左右に操作ノブ１を摺動操作する際、ガタツキなく安定して摺動する。 As a result, the operation knob 1 is slidably held on the front fin 30, and when the operation knob 1 is slid left and right, the sliding contact portion 18 of the knob body 10 slides while in contact with the load applying member 17. At the same time, the guide convex portion 32 slides while being guided by the semi-cylindrical portion 32a at the tip thereof and the ribs 38 (FIG. 11) on the upper and lower surfaces thereof in contact with each other in the guide concave portion 12. As a result, the operation knob 1 slides stably without rattling when the front fin 30 is shaken up and down or when the operation knob 1 is slid left and right.

前可動ルーバ３のアッセンブリは、操作ノブ１を組み付けた前フィン３０、上側の前フィン３６及び下側の前フィン３７が、両側に配置した軸受部３ａに軸支され、リンクバー３ｂが各前フィン３０、３６，３７の連結軸に連結され、その状態で、リテーナ２の前部内に組み付けられる。ベゼル５は、リテーナ２の前部に嵌着される。 In the assembly of the front movable louver 3, the front fin 30 to which the operation knob 1 is assembled, the upper front fin 36 and the lower front fin 37 are pivotally supported by the bearing portions 3a arranged on both sides, and the link bar 3b is each front. It is connected to the connecting shafts of the fins 30, 36, and 37, and is assembled in the front portion of the retainer 2 in that state. The bezel 5 is fitted to the front of the retainer 2.

上記構成のレジスタは、自動車の車内のインストルメントパネルやダッシュボードの部分に、そのリテーナ２の末端を図示しない通風ダクトに接続するようにして装着される。通風ダクトから送られる空気は、リテーナ２内の通風路９から空気吹出口８を通して吹き出される。 The register having the above configuration is attached to an instrument panel or dashboard in an automobile so that the end of the retainer 2 is connected to a ventilation duct (not shown). The air sent from the ventilation duct is blown out from the ventilation passage 9 in the retainer 2 through the air outlet 8.

前可動ルーバ３及び後可動ルーバ４をニュートラル状態としてレジスタに送風すると、図６に示すように、空気流は通風路９を通過し、空気吹出口８から前方に送風される。このとき、前フィン３０の操作ノブ１は、その厚さが前フィン３０の約１．５倍程度と薄く形成されるため、操作ノブ１の送風方向の投影面積は小さく、送風時の圧力損失を低減し、異音の発生も低減することができる。 When the front movable louver 3 and the rear movable louver 4 are blown to the register in the neutral state, the air flow passes through the ventilation passage 9 and is blown forward from the air outlet 8 as shown in FIG. At this time, since the thickness of the operation knob 1 of the front fin 30 is formed to be as thin as about 1.5 times that of the front fin 30, the projected area of the operation knob 1 in the blowing direction is small, and the pressure loss during blowing is small. It is possible to reduce the generation of abnormal noise.

空気の吹出向きを上または下に調整する場合、前可動ルーバ３の操作ノブ１を上または下に回動させて調整する。操作ノブ１を持って上または下に回動させると、図２に示すように、操作ノブ１が装着された前フィン３０がその支軸３０ａを軸に上下に回動し、その回動力がリンクバー３ｂを介して他の前フィン３６，３７に伝達され、前可動ルーバ３の上下方向の向きが変化し、空気の吹出方向が上下に調整される。 When adjusting the direction of air blowing up or down, the operation knob 1 of the front movable louver 3 is rotated up or down to adjust. When the operation knob 1 is held and rotated up or down, as shown in FIG. 2, the front fin 30 to which the operation knob 1 is mounted rotates up and down around the support shaft 30a, and the turning power is generated. It is transmitted to the other front fins 36 and 37 via the link bar 3b, the vertical direction of the front movable louver 3 is changed, and the air blowing direction is adjusted up and down.

一方、空気の吹出向きを左右に調整する場合、操作ノブ１を左または右に移動させて調整する。操作ノブ１を持って左または右に動かすと、操作ノブ１は前フィン３０上を摺動し、水平方向（横方向）に移動する。これに伴い、図７に示すように、操作ノブ１の後部の二股係合部２５が、後可動ルーバ４の後フィン４０を、その係合部４１を介して左右に回動させ、リンクバー４５を介して、各後フィン４０がその係合部４１を軸に同期して回動し、後可動ルーバ４の左右方向の向きが変化し、空気の吹出方向が左または右に調整される。 On the other hand, when adjusting the air blowing direction to the left or right, the operation knob 1 is moved to the left or right for adjustment. When the operation knob 1 is held and moved to the left or right, the operation knob 1 slides on the front fin 30 and moves in the horizontal direction (horizontal direction). Along with this, as shown in FIG. 7, the bifurcated engaging portion 25 at the rear of the operation knob 1 rotates the rear fin 40 of the rear movable louver 4 to the left and right via the engaging portion 41, and the link bar. Through the 45, each rear fin 40 rotates synchronously with the engaging portion 41 thereof, the direction of the rear movable louver 4 in the left-right direction is changed, and the air blowing direction is adjusted to the left or right. ..

このとき、前フィン３０上の操作ノブ１は、そのノブ本体１０内の摺接部１８が前フィン３０側の荷重付与部材１７と摺接し、ノブ本体１０の前部１１の湾曲凹面部１１ａが前フィン３０の半円柱部３４と摺接し、前部１１内のガイド凹部１２の内面が、前フィン３０のガイド凸部３２のリブ３８及び先端の半円柱部３４と摺接する。これにより、操作ノブ１の摺動操作時、ガタツキやゴリゴリ感を生じずに、最少の摩擦抵抗で操作荷重を生じさせ、操作ノブ１を円滑に操作することができる。 At this time, in the operation knob 1 on the front fin 30, the sliding contact portion 18 in the knob main body 10 is in sliding contact with the load applying member 17 on the front fin 30 side, and the curved concave surface portion 11a of the front portion 11 of the knob main body 10 is formed. It is in sliding contact with the semi-cylindrical portion 34 of the front fin 30, and the inner surface of the guide recess 12 in the front portion 11 is in sliding contact with the rib 38 of the guide convex portion 32 of the front fin 30 and the semi-cylindrical portion 34 at the tip. As a result, when the operation knob 1 is slid, an operation load is generated with the minimum frictional resistance without causing rattling or rattling, and the operation knob 1 can be operated smoothly.

このように、ノブ本体１０のカバー凹部１４を設けた平面部分の厚さが前フィン３０の厚さより薄く、前フィン３０の露出面とノブ本体１０の前部１１平面とノブ後部１３の平面とが、略面一となるので、操作ノブ装置の厚さを、従来のものより大幅に薄くすることができる。これにより、レジスタの見栄えや意匠性を向上させ、送風時の圧力損失や騒音を低減することができる。また、前フィン３０の操作ノブ１との係合面に、操作ノブ１を係合保持するための溝は必要なく、前フィン３０の長手方向の撓み強度を、十分な強度に保持することができる。 As described above, the thickness of the flat surface portion of the knob body 10 provided with the cover recess 14 is thinner than the thickness of the front fin 30, the exposed surface of the front fin 30, the front 11 flat surface of the knob body 10, and the flat surface of the knob rear portion 13. However, since it is substantially flush with each other, the thickness of the operation knob device can be significantly reduced as compared with the conventional one. As a result, the appearance and design of the register can be improved, and pressure loss and noise at the time of blowing can be reduced. Further, the engagement surface of the front fin 30 with the operation knob 1 does not require a groove for engaging and holding the operation knob 1, and the bending strength in the longitudinal direction of the front fin 30 can be maintained at a sufficient strength. can.

なお、上記実施形態のレジスタでは、ノブ本体１０とノブ後部１３は、前フィン３０の上面側を露出させ、下面側を覆うように、前フィン３０に対し摺動可能に取り付けたが、それとは逆に、ノブ本体１０とノブ後部１３を、前フィン３０の下面側を露出させ、上面側を覆うように、前フィン３０に対し摺動可能に取り付けることもできる。 In the register of the above embodiment, the knob body 10 and the knob rear portion 13 are slidably attached to the front fin 30 so as to expose the upper surface side of the front fin 30 and cover the lower surface side. On the contrary, the knob main body 10 and the knob rear portion 13 can be slidably attached to the front fin 30 so as to expose the lower surface side of the front fin 30 and cover the upper surface side.

また、前フィン３０を含む前可動ルーバ３を水平横方向に配置したが、前フィン３０を含む前可動ルーバ３を垂直縦方向に配置し、後可動ルーバ４を水平横方向に配置することもできる。その場合、ノブ本体とノブ後部は、前フィンの他方の面側を露出させ、一方の面側を覆うように、前フィンに対し摺動可能に取り付けられることとなる。 Further, although the front movable louver 3 including the front fin 30 is arranged in the horizontal horizontal direction, the front movable louver 3 including the front fin 30 may be arranged in the vertical vertical direction, and the rear movable louver 4 may be arranged in the horizontal horizontal direction. can. In that case, the knob body and the rear portion of the knob are slidably attached to the front fin so as to expose the other surface side of the front fin and cover the one surface side.
