Description

本発明は、例えばヘッドライトなど、車両に取付けた状態で上向きとなりすぎ、他車に幻惑を生じさせたり、或いは、照射方向が下向きとなりすぎて自車の前方への照射範囲が減じて障害物の発見に支障を来すことのないように、車両に取付ける際には照射軸を調整可能として取付けられるように形成された光軸調整装置などに用いられる位置調整部材に関するものである。   The present invention is an obstacle such as a headlight that is too upward when mounted on a vehicle, causing illusion to other vehicles, or the irradiation direction is too downward and the irradiation range to the front of the vehicle is reduced. It is related with the position adjustment member used for the optical-axis adjustment apparatus etc. which were formed so that an irradiation axis could be adjusted when attaching to a vehicle so that it might not interfere with discovery of this.

従来のこの種の光軸調整装置としては、例えば特開平８−１１５６０４号公報に示されるように、反射鏡（１１）などに、ほぼ長方形の開口をナット取付穴（１１ａ）として設けておくと共に、一方の調整ナット（２）には、略Ｖ字状に形成されたクリップ（２３）を先端側に形成しておき、このクリップ（２３）を前記取付穴（１１ａ）に圧接すると前記略Ｖ字状としたクリップ（２３）が変形して取付穴（１１ａ）を通過し、通過後には再度Ｖ字状に拡がって、調整ナット（２）の背面とで反射鏡（１１）の肉厚を挟んで（特開平８−１１５６０４号公報の図２参照）保持される。   As a conventional optical axis adjusting device of this type, for example, as shown in JP-A-8-115604, a substantially rectangular opening is provided as a nut mounting hole (11a) in a reflecting mirror (11) or the like. On one adjustment nut (2), a clip (23) formed in a substantially V shape is formed on the distal end side, and when this clip (23) is pressed into the mounting hole (11a), the substantially V-shaped clip (23) is formed. The shaped clip (23) is deformed and passes through the mounting hole (11a). After passing, the clip (23) spreads again into a V shape, and the thickness of the reflecting mirror (11) is increased with the back of the adjusting nut (2). It is held (see FIG. 2 of JP-A-8-115604).

このときに、前記調整ナット（２）の底面と、前記クリップ（２３）の先端とを中高の形状として反射鏡（１１）を挟持するものとしておくことで、図４（特開平８−１１５６０４号公報）に示すように調整ネジ（３）の傾きに自由度を与え、例えば反射鏡（１１）と車体とが平行でないときに生じる調整ネジ（３）及び調整ナット（２）に生じる歪み応力を緩和する。   At this time, the reflecting mirror (11) is sandwiched between the bottom surface of the adjusting nut (2) and the tip of the clip (23) with a medium-high shape. As shown in the publication, the degree of freedom of the inclination of the adjusting screw (3) is given. For example, the distortion stress generated in the adjusting screw (3) and the adjusting nut (2) generated when the reflecting mirror (11) and the vehicle body are not parallel to each other. ease.

また、前記調整ナット（２）の底面は、上記と直交する方向にも中高となる傾斜を有しており図５（特開平８−１１５６０４号公報）にも示したように図４と直交する方向に生じる歪み応力も緩和するものとされている。よって、前記調整ネジ（３）及び調整ナット（２）は反射鏡（１１）に対して、所定の範囲での首振り動作が可能であり、これにより反射鏡（１１）側にも過大な応力が加わることがなく、歪みによる配光の変化などを生じないものとすることが出きる。
特開平８−１１５６０４号公報 Further, the bottom surface of the adjusting nut (2) has an inclination that becomes a medium height in the direction orthogonal to the above, and is orthogonal to FIG. 4 as shown in FIG. 5 (Japanese Patent Laid-Open No. 8-115604). The strain stress generated in the direction is also relaxed. Therefore, the adjusting screw (3) and the adjusting nut (2) can swing in a predetermined range with respect to the reflecting mirror (11), thereby causing excessive stress on the reflecting mirror (11) side. It is possible to prevent the light distribution from changing due to distortion.
JP-A-8-115604

しかしながら、上記した従来の光軸調整装置の構成においては、前記調整ナット（２）とクリップ（２３）とで、別体として成形された反射鏡（１１）を挟持し取付ける構成であるので、前記反射鏡（１１）の形成時のバラツキなどの影響を受けやすく、例えば、反射鏡（１１）の厚みが厚目の場合には、スムースな動作が損なわれたり、或いは、逆に反射鏡（１１）の厚みが薄目の場合には、ガタを生じて走行時に異音を生じるなどの問題点があった。   However, in the configuration of the conventional optical axis adjusting device described above, the reflecting mirror (11) formed as a separate body is sandwiched and attached by the adjusting nut (2) and the clip (23). For example, when the thickness of the reflecting mirror (11) is thick, the smooth operation is impaired, or conversely, the reflecting mirror (11) is easily affected. In the case where the thickness of) is thin, there is a problem such that a rattling occurs and an abnormal noise is generated during traveling.

更に言えば、反射鏡（１１）の形状、デザインによっては、必ずしも、最適の位置にナット取付穴（１１ａ）が設けられない場合も生じたり、或いは、前記ナット取付穴（１１ａ）が前面から見えるものとなって、デザインを損なうなどの問題点も生じるものとなり、これらの点の解決が課題とされるものとなっていた。   Furthermore, depending on the shape and design of the reflector (11), the nut mounting hole (11a) may not necessarily be provided at the optimum position, or the nut mounting hole (11a) can be seen from the front. As a result, problems such as damage to the design also occur, and the solution of these points has been a problem.

本発明は、上記した従来の課題を解決するための具体的な手段として、中心にネジ取付け部を有し外形に第１樹脂から成る球面部を有するナット部と、前記ナット部の球面部を揺動可能として包囲する第２樹脂から成るホルダー部を有し、前記第１樹脂は第２樹脂に比べて高い耐熱温度を有する位置調整部材であって、前記ナット部は、外形が最大径の部分を含む球面状、若しくは、前記最大径の部分を残し両端部が削除された略円板状とされ、前記最大径の部分には、この球面の中心点で対峙するように一対の突出部が形成されており、前記ホルダー部は、内部に前記ナット部の球面部と接して摺動可能として嵌着されている中空部を備え、前記ナット部の突出部に対応する位置には、前記ナット部の最大径よりも適宜に大きい内径で、前記突出部の幅よりも大きな開口が前記外形まで達するように設けられており、前記位置調整部材の形成に当たっては、予めにナット部を形成しておき、前記ナット部の突出部を両側で保持した状態で該ナット部に対し前記ホルダー部のインサート成形を行うことで、両者の一体化が行われている構成とされていることを特徴とする位置調整部材を提供することで課題を解決するものである。 As specific means for solving the above-described conventional problems, the present invention includes a nut portion having a screw mounting portion at the center and a spherical portion made of a first resin on the outer shape, and a spherical portion of the nut portion. have a holder portion made of a second resin surrounding the swingable, said first resin is a position adjusting member having a higher heat resistance temperature than the second resin, wherein the nut portion, the outer shape of maximum diameter A spherical shape including a portion, or a substantially disk shape with both end portions removed while leaving the maximum diameter portion, and a pair of protrusions on the maximum diameter portion so as to confront each other at the center of the spherical surface The holder portion includes a hollow portion that is slidably fitted in contact with the spherical surface portion of the nut portion, and the holder portion is provided at a position corresponding to the protruding portion of the nut portion. The inner diameter is appropriately larger than the maximum diameter of the nut part. Than the width of the projecting portion is provided so that the large opening reaches the outer, the In forming the positioning member, previously formed a nut portion in advance, and holds the protruding portion of the nut part on both sides By solving the problem by providing a position adjusting member characterized in that the two are integrated by performing insert molding of the holder part on the nut part in a state It is.

併せて、本発明では、前記ホルダー部の外形には車体、灯体ハウジング、或いは、灯具反射鏡に固定するための係着部を設けた上記の位置調整部を用いたことを特徴とする車両用灯具の光軸調整装置、及び、前記光軸調整用装置の形成に当たっては、予めにナット部を形成しておき、該ナット部に対し前記ホルダー部のインサート成型を行うことで、両者の一体化が行われている構成とされていることを特徴とする車両用灯具の光軸調整装置を提供することで生産性も向上させ、コストダウンも可能とするものである。   In addition, in the present invention, the outer shape of the holder portion includes the vehicle body, the lamp body housing, or the position adjusting portion provided with the engaging portion for fixing to the lamp reflector. In forming the optical axis adjusting device for a lamp and the optical axis adjusting device, a nut portion is formed in advance, and insert molding of the holder portion is performed on the nut portion, thereby integrating the two. By providing an optical axis adjusting device for a vehicular lamp characterized by having a structure that is made into a product, productivity can be improved and costs can be reduced.

本発明の光軸調整装置は光軸調整ネジに螺着される光軸調整用のナット部は、反射鏡、或いはハウジングなどに取付けが行われるホルダー部と予めに、いわゆる、ボールジョイント機構で接合されているので、組立時に部品精度による動作の軽重にバラツキなどを生じることなく、また、それらを調整するための繁雑さも生じることなく、均一な品質の光軸調整装置が簡便にできるものとして品質の向上、生産性の向上に極めて優れた効果を奏するものである。   In the optical axis adjusting device of the present invention, an optical axis adjusting nut portion screwed to an optical axis adjusting screw is joined in advance with a so-called ball joint mechanism to a holder portion to be attached to a reflecting mirror or a housing. Therefore, the quality of the optical axis adjustment device with uniform quality can be easily achieved without causing variations in operation due to the accuracy of parts during assembly and without the complexity of adjusting them. It has an extremely excellent effect on improving the productivity and productivity.

つぎに、本発明を図に示し実施形態に基づいて詳細に説明する。図１に符号１で示すものは、本発明に係る光軸調整装置であり、この光軸調整装置１は、光軸調整ネジ２と、ナット部３と、ホルダー部４とを主として構成されている。尚、必要に応じては、前記光軸調整ネジ２を円滑に回転させるためのワッシャ、灯具内を防水するためのＥリングなどを設けても良いものである。   Next, the present invention will be described in detail with reference to the drawings. What is denoted by reference numeral 1 in FIG. 1 is an optical axis adjusting device according to the present invention, and this optical axis adjusting device 1 mainly comprises an optical axis adjusting screw 2, a nut portion 3, and a holder portion 4. Yes. If necessary, a washer for smoothly rotating the optical axis adjusting screw 2 and an E-ring for waterproofing the inside of the lamp may be provided.

図２、図３は、前記ナット部３を示すものであり、図２はナット部３を光軸調整ネジ２の挿着側からみた図であり、基本的には球面状の形状の物体を両側からほぼ当分に切除して、平行な平坦部３ａが形成された形状とされている。そして、その一方の平坦部３ａから他方の平坦部３ａに向けて、前記光軸調整ネジ２を螺着させるためのネジ部が形成されるものとされている。   2 and 3 show the nut portion 3, and FIG. 2 is a view of the nut portion 3 as seen from the insertion side of the optical axis adjusting screw 2. Basically, an object having a spherical shape is shown. It has a shape in which parallel flat portions 3a are formed by cutting away from both sides for a time. A screw portion for screwing the optical axis adjusting screw 2 is formed from one flat portion 3a to the other flat portion 3a.

ここで、本発明においては、前記ナット部は、前記光軸調整ネジ２に比べ軟質なポリアセタール樹脂で形成されるものであるので、セルフタッピングなどの手段で十分に前記光軸調整ネジ２の螺着が可能であり、よって、図２に示すようにナット部３の中心に向かい４個の突起３ｂが突出するようにして略十文字状の形状となるネジ取付孔３ｃを設けておき、それぞれの突起３ｂの頂点にセルフタッピングを行いながら光軸調整ネジ２をねじ込むことで、比較的に少ない力で光軸調整ネジ２の取付けが確実に行えるものとしている。尚、図面ではナット中心部に光軸調整ネジ２を螺着する雌ネジを設けたものとしているが、これは、雄ネジを設けるものとしても良い。   Here, in the present invention, the nut portion is formed of a soft polyacetal resin as compared with the optical axis adjusting screw 2, so that the screw of the optical axis adjusting screw 2 can be sufficiently screwed by means such as self-tapping. Therefore, as shown in FIG. 2, screw mounting holes 3c having a substantially cross-shaped shape are provided so that four protrusions 3b protrude toward the center of the nut portion 3, By screwing the optical axis adjusting screw 2 while self-tapping the apex of the protrusion 3b, the optical axis adjusting screw 2 can be securely attached with a relatively small force. In the drawings, a female screw for screwing the optical axis adjusting screw 2 is provided at the center of the nut. However, this may be provided with a male screw.

ここで、本発明においては、前記ナット部３にピン３ｄを設けるものであり、このピン３ｄは、前記ネジ取付孔３ｃに対して直角方向であり、且つ、前記ナット部３の最大径の部分から最大径の部分の球面の中心点で対峙するように両方向に向けて、即ち、球状であるナット部３の直径の双方の延長方向に向けて突出するものとされている。   In the present invention, the nut portion 3 is provided with a pin 3d, and the pin 3d is in a direction perpendicular to the screw mounting hole 3c and has the largest diameter portion of the nut portion 3. It protrudes in both directions so as to confront each other at the center point of the spherical surface of the largest diameter portion, that is, in the extending direction of both diameters of the nut portion 3 that is spherical.

図４は、前記ナット部３を揺動（首振り）可能として保持するためのホルダー部４であり、このホルダー部４の内面には、前記ナット部３が嵌合する略球状の中空部４ａが設けられている。尚、実際には、前記ナット部３は、平坦部３ａよりも最大径の部分の方が径が大きく、それに伴い、ホルダー部４においても中空部４ａは、最大径の部分が中心付近に存在するので、個々の部品としてそれぞれに形成されているナット部３とホルダー部４とを組み立てるのは不可能である。   FIG. 4 shows a holder portion 4 for holding the nut portion 3 so that the nut portion 3 can swing (swing), and a substantially spherical hollow portion 4 a into which the nut portion 3 is fitted on the inner surface of the holder portion 4. Is provided. Actually, the nut portion 3 has a larger diameter at the maximum diameter portion than the flat portion 3a. Accordingly, the hollow portion 4a of the holder portion 4 also has the maximum diameter portion near the center. Therefore, it is impossible to assemble the nut portion 3 and the holder portion 4 formed as individual parts.

そこで、本発明では、まず、前記ナット部３をガラスファイバー入りのポリアセタール樹脂を使用して金型中（図示せず）で形成しておく。その後、ナット部３を図５に示すように、金型１１〜金型１４で構成されるホルダー形成用金型中に前記ナット部３を設置し、次いで、、これら金型１１〜金型１４で形成される空隙にナイロン樹脂を注入してインサート成型を行う。   Therefore, in the present invention, first, the nut portion 3 is formed in a mold (not shown) using a polyacetal resin containing glass fiber. After that, as shown in FIG. 5, the nut portion 3 is installed in a holder forming die composed of the die 11 to the die 14, and then the die 11 to the die 14. Nylon resin is injected into the gap formed by insert molding.

このときに、金型１１〜金型１４中でインサートされるナット部３を、周囲にナイロン樹脂が注入されて保持される状態となるまで、所定の位置に保持しておくのが金型１２に設けられたピン挿入部１２ａと、金型１３に設けられたピン挿入部１３ａとであり、それぞれには、前記ナット部３に設けられたピン３ｄが挿入されて、金型１１〜金型１４で形成される空隙中で所定位置を保つものとなる。   At this time, it is the mold 12 to hold the nut portion 3 inserted in the mold 11 to the mold 14 in a predetermined position until the nut portion 3 is injected and held in the periphery. A pin insertion part 12a provided in the mold 13 and a pin insertion part 13a provided in the mold 13, each having a pin 3d provided in the nut part 3 inserted therein, and the molds 11 to 11 14 to maintain a predetermined position in the gap formed.

また、前記ピン挿入部１３ａは適宜にピン３ｄより太いものとされて、光軸調整装置１として形成された後には、前記ピン３ｄの周囲にホルダー部４が密着しないように開口４ｂを有するものとし、図１にも示すように、このピン３ｄが設けられている方向に対しても光軸調整ネジ２に対して適宜な傾きが与えられるものとされ、灯具に対して上下方向の調整と、左右方向の調整とを同時に行ったときにも、双方の傾きに対して対応できるものとされている。   Further, the pin insertion portion 13a is appropriately thicker than the pin 3d and, after being formed as the optical axis adjusting device 1, has an opening 4b so that the holder portion 4 does not adhere to the periphery of the pin 3d. As shown in FIG. 1, the optical axis adjusting screw 2 is given an appropriate inclination with respect to the direction in which the pin 3d is provided. Even when the adjustment in the left-right direction is performed at the same time, it is possible to cope with both inclinations.

尚、ナット部３と、ホルダー部４とを一体化する成型工程においては、双方が樹脂部材同士であり、例えば、金属部材と樹脂部材との一体成型の場合に比較して、両者の溶融温度が近いので、溶着などの発生の可能性も高くなるので、必要に応じては、既に成型が行われているナット部３の側にシリコーンオイルなどの離型剤の適宜量を塗布しておくなども良い。   In addition, in the molding process in which the nut portion 3 and the holder portion 4 are integrated, both are resin members. For example, compared to the case of integral molding of a metal member and a resin member, both melting temperatures are Since there is a high possibility of occurrence of welding or the like, if necessary, an appropriate amount of a release agent such as silicone oil is applied to the side of the nut portion 3 that has already been molded. Etc. are also good.

本実施例では、第１樹脂としてガラスファイバー入りのポリアセタール樹脂を用い、第２樹脂としてナイロン樹脂を用いた。第１樹脂の熱変形温度と、第２樹脂の射出成形温度とを比べたときに、第１樹脂の温度が第２樹脂の温度と同等以上のグレードの樹脂を選定した。第１樹脂の耐熱性が第２樹脂の耐熱性に比べて高くないと、第２樹脂の成型時に溶着の問題が発生する。さらに、第１樹脂の耐熱性が第２樹脂に比べて高くとも、第１樹脂の熱変形温度が低いと第２樹脂の注入圧力によっては変形する恐れがあるからである。   In this example, a polyacetal resin containing glass fibers was used as the first resin, and a nylon resin was used as the second resin. When the thermal deformation temperature of the first resin was compared with the injection molding temperature of the second resin, a resin having a grade in which the temperature of the first resin was equal to or higher than the temperature of the second resin was selected. If the heat resistance of the first resin is not higher than the heat resistance of the second resin, a problem of welding occurs when the second resin is molded. Furthermore, even if the heat resistance of the first resin is higher than that of the second resin, it may be deformed depending on the injection pressure of the second resin if the heat deformation temperature of the first resin is low.

また、第１樹脂からなる成型品と、第２樹脂から成るせいけいひんを比べた場合において、第１樹脂から成る成型品のほうが摩擦係数に少ないものとすると良い。摩擦係数の少ないものを第１樹脂に用いるとナット部の滑りが良くなり、スムーズに摺動可能となるからである。尚、上記したポリアセタール樹脂はナイロン樹脂に比べて滑りがよい。第１樹脂材料としては上記ポリアセタール樹脂に限らず熱可塑性樹脂、例えばエポキシ樹脂であっても良く、第２樹脂としては例えばポリスチレン樹脂を用いることもできる。   Further, when the molded product made of the first resin and the seizure made of the second resin are compared, it is preferable that the molded product made of the first resin has a smaller friction coefficient. This is because, when a material having a small friction coefficient is used for the first resin, the nut portion slides better and can be slid smoothly. Note that the above-mentioned polyacetal resin is more slippery than nylon resin. The first resin material is not limited to the polyacetal resin, and may be a thermoplastic resin, for example, an epoxy resin, and the second resin may be, for example, a polystyrene resin.

図６は、上記で説明したナット部３の製造工程を示すもので、この実施形態では、略球状の外形部分を形成する金型１４、金型１５と、ピン３ｄ部分を形成する金型１６、金型１７とを別体としている。また、金型１６にはナット部３を形成するためのキャビティに樹脂を注入するためのゲート１６ａが設けられている。そして、ゲート１６ａから樹脂が注入されナット部３が形成された後には、この実施形態においては、金型１４、金型１５のみが外され、前記ナット部３は依然として金型１６、金型１７により成型機内の定位置に定方向で保持された状態にある。   FIG. 6 shows a manufacturing process of the nut portion 3 described above. In this embodiment, a die 14 and a die 15 that form a substantially spherical outer shape portion, and a die 16 that forms a pin 3d portion. The mold 17 is a separate body. The mold 16 is provided with a gate 16a for injecting resin into a cavity for forming the nut portion 3. And after resin is inject | poured from the gate 16a and the nut part 3 is formed, in this embodiment, only the metal mold | die 14 and the metal mold | die 15 are removed, and the said nut part 3 is still the metal mold | die 16 and the metal mold | die 17 in it. Thus, it is held in a fixed direction at a fixed position in the molding machine.

図７は上記に説明したナット部３にホルダー部４を形成する工程を示すものであり、このときに、ナット部３は上記に説明したように金型１６、金型１７により定位置で定方向を維持している状態であるので、図５の場合とほぼ同様な構成とした金型１１と金型１４とで上下方向を挟むようにすると共に、金型１６、金型１７の部分を避けるように形成した金型１８、金型１９でナット部３の円周部分を覆う部分を形成する。   FIG. 7 shows a process of forming the holder portion 4 on the nut portion 3 described above. At this time, the nut portion 3 is fixed at a fixed position by the mold 16 and the mold 17 as described above. Since the direction is maintained, the upper and lower directions are sandwiched between the mold 11 and the mold 14 having substantially the same structure as in FIG. A portion that covers the circumferential portion of the nut portion 3 is formed by the mold 18 and the mold 19 that are formed so as to be avoided.

このようにすることで、ナット部３の形成工程に連続する工程でホルダー部４が形成できるものとなり、しかも、ナット部３を所定位置に保持した状態で、ホルダー部４の形成が行えるものとなるので、製品としての精度も高くすることができ、生産効率も向上させることができるものとなる。   By doing in this way, the holder part 4 can be formed in a process continuous with the process of forming the nut part 3, and the holder part 4 can be formed while the nut part 3 is held in a predetermined position. Therefore, the accuracy as a product can be increased, and the production efficiency can be improved.

加えて、以上の構成としたことで、本発明の光軸調整装置１は、反射鏡など灯具側の部品の肉厚などを利用して光軸調整ネジ１の揺動を行うものでなく、光軸調整装置１の側に設けられたナット部３とホルダー部４とで揺動を行うものであるので、車両用灯具の精度に影響を受けることなく動作が可能なものとなる。   In addition, with the above configuration, the optical axis adjusting device 1 of the present invention does not swing the optical axis adjusting screw 1 by utilizing the thickness of a component on the lamp side such as a reflector, Since the nut portion 3 and the holder portion 4 provided on the optical axis adjusting device 1 side swing, the operation can be performed without being affected by the accuracy of the vehicle lamp.

従って、使用する車両用灯具に影響を受けることがなくなり、予めに標準部品として大量生産しておき、常備部品としておくことが可能となり、例えば、生産ラインの変更などにも対応が容易であり、また、補修部品としても使用可能であるので、部品管理が簡素化し生産性が向上する。   Therefore, it is not affected by the vehicular lamp to be used, can be mass-produced as a standard part in advance, and can be kept as a permanent part, for example, it is easy to respond to changes in production lines, etc. Moreover, since it can be used as a repair part, parts management is simplified and productivity is improved.

更には、本発明の構成では、ナット部３をホルダ部４内に包み込む構成としたインサート成型により一体化していることで、容易に破損を生じることのない十分な強度のものが得られ、例えば、近年の光源が放電灯化され、起動回路などが付属されて、重量化、大型化した灯具に対しても十分な強度と精度を保つ状態で支持できるものとする。   Furthermore, in the configuration of the present invention, the nut portion 3 is integrated by insert molding in which the nut portion 3 is wrapped in the holder portion 4, so that a material having sufficient strength that is not easily damaged can be obtained. It is assumed that a recent light source has been replaced with a discharge lamp and a starting circuit or the like is attached so that it can be supported with sufficient strength and accuracy even with a weighted and enlarged lamp.

図８、及び、図９は本発明の位置調整部材を光軸調整装置１としたときの使用例であり、灯具２０のハウジング２１内には反射鏡２２が設けられ、この反射鏡２２は光軸調整装置１により照射方向が調整可能とされている。そして、例えば反射鏡２２の向かって右下方には、光軸調整ネジ１をハウジング２１側に取付け、ナット部３を含むホルダ部４を反射鏡２２側に取付けられた第一の光軸調整装置１Ａが設けられている。   8 and 9 show an example of use when the position adjusting member of the present invention is the optical axis adjusting device 1, and a reflecting mirror 22 is provided in the housing 21 of the lamp 20, and the reflecting mirror 22 is a light beam. The irradiation direction can be adjusted by the axis adjusting device 1. Then, for example, on the lower right side of the reflecting mirror 22, a first optical axis adjusting device in which the optical axis adjusting screw 1 is attached to the housing 21 side and the holder portion 4 including the nut portion 3 is attached to the reflecting mirror 22 side. 1A is provided.

また、前記第一の光軸調整装置１Ａの水平の左下方には、同様に、光軸調整ネジ１をハウジング２１側に取付け、ナット部３を含むホルダ部４を反射鏡２２側に取付けられた第二の光軸調整装置１Ｂが設けられるものとされているが、この第二の光軸調整装置１Ｂはハウジング２１に対して光軸調整ネジ１が回動可能となっている。   Similarly, on the lower left side of the first optical axis adjusting device 1A, the optical axis adjusting screw 1 is attached to the housing 21 side, and the holder part 4 including the nut part 3 is attached to the reflecting mirror 22 side. The second optical axis adjusting device 1B is provided, and the optical axis adjusting screw 1 is rotatable with respect to the housing 21 in the second optical axis adjusting device 1B.

そして、前記第一の光軸調整装置１Ａの垂直の上方には、第二の光軸調整装置１Ｂと同様にハウジング２１に対して光軸調整ネジ１を回動可能とした第三の光軸調整装置１Ｃが設けられている。このようにすることで、第二の光軸調整装置１Ｂの光軸調整ネジ１を回動させればナット部３は光軸調整ネジ１上を前後に移動し、これにより、ハウジング２１に対して反射鏡２２の左端部は前後方向に移動するものとなり、即ち、光は左右に照射方向を変えられる（図では向かって左の例で示す）ものとなる。   Then, above the first optical axis adjustment device 1A, a third optical axis that allows the optical axis adjustment screw 1 to rotate with respect to the housing 21 in the same manner as the second optical axis adjustment device 1B. An adjusting device 1C is provided. By doing in this way, if the optical axis adjustment screw 1 of the second optical axis adjustment device 1B is rotated, the nut portion 3 moves back and forth on the optical axis adjustment screw 1, and thereby, with respect to the housing 21. Thus, the left end portion of the reflecting mirror 22 moves in the front-rear direction, that is, the light can be changed in the irradiation direction to the left and right (shown in the left example in the figure).

図示は省略するが、同様に、第三の光軸調整装置１Ｃの光軸調整ネジ１を回動させることで、光を上下に照射方向を生えられるものとなる。そして、本発明のナット部３ではピン３ｄの周囲に空隙を設けたことで、前記ホルダー部４内で全ての方向に回動可能であり、従って、光軸調整ネジ１及びナット部３に対して無理な力が加わることはない。   Although illustration is omitted, similarly, by rotating the optical axis adjusting screw 1 of the third optical axis adjusting device 1C, the light can be irradiated in the vertical direction. In the nut portion 3 of the present invention, a gap is provided around the pin 3d so that it can be rotated in all directions within the holder portion 4. Therefore, the nut portion 3 can be rotated with respect to the optical axis adjusting screw 1 and the nut portion 3. No excessive force is added.

尚、例えば、車両における個人用の空調機の吹き出し口、或いは、航空機における個人用の読書灯など、ほぼ全方向に向きの調整が可能であることが要求される機器など、いわゆるボールジョイント、或いは、これに類似する機構が用いられている用途にも適用できる。   In addition, for example, a so-called ball joint such as a device required to be able to adjust the orientation in almost all directions, such as a personal air conditioner outlet in a vehicle or a personal reading light in an aircraft, or the like It can also be applied to applications where a similar mechanism is used.
