Description

本発明は、車両に装着される車両用装着品に関する。   The present invention relates to a vehicle attachment to be attached to a vehicle.

近年、車両には、電波（ミリ波）を用いて車両周囲の障害物を検知するレーダが搭載されている。ミリ波レーダにより車両と障害物との距離や相対速度を計測して、運転者に障害物の存在を通報したり、障害物を自動的に回避したりされている。
レーダの検知側には、レーダを保護するレドームが配置される。このレドームは、車両の前面に装着された合成樹脂製のラジエータグリルの中央部に配置され、車両の標章を表すエンブレムと一体化されたものがある。 In recent years, a vehicle is equipped with a radar that detects an obstacle around the vehicle using radio waves (millimeter waves). The millimeter wave radar measures the distance between the vehicle and the obstacle and the relative velocity to notify the driver of the presence of the obstacle or automatically avoid the obstacle.
A radome protecting the radar is disposed on the detection side of the radar. This radome is disposed at the center of a synthetic resin radiator grille mounted on the front of a vehicle, and is integrated with an emblem representing the vehicle's mark.

ラジエータグリルやエンブレム等の車両の外面に装着される車両用装着品は、高級感や質感を付与して車両の意匠性を向上させるために、金属光輝面が形成されることが多い。   A vehicle attachment such as a radiator grille or an emblem attached to the outer surface of a vehicle often has a metallic bright surface in order to impart a high-class feel and texture to improve the design of the vehicle.

特許文献１から３には、透明樹脂と不透明樹脂の間に金属光輝層（金属光輝面）を配置したレドームが開示されている。レドームでは、ミリ波レーダの透過を阻害しないために、金属光輝層として、インジウムの蒸着層またはスパッタリング層が採用されている。
このようなレドームは、ラジエータグリルと並んで配置されても違和感のない金属光輝性と、ミリ波レーダが障害物を検知するに十分な電波透過性能とを備えている。 Patent Documents 1 to 3 disclose a radome in which a metallic glitter layer (metallic glitter surface) is disposed between a transparent resin and an opaque resin. In the radome, a deposited layer or a sputtered layer of indium is employed as the metallic glitter layer in order not to inhibit the transmission of the millimeter wave radar.
Such a radome has metallic luster that does not have a sense of incongruity even when placed side by side with the radiator grille, and radio wave transmission performance sufficient for the millimeter wave radar to detect an obstacle.

しかしながら、上述したレドームは、正面（車外側）から見ると、金属光輝面のみならず、金属光輝面の周囲でも光が反射してしまうという問題がある。つまり、レドームの全面が光沢感を呈するため、金属光輝面とその周囲とのコントラストが低くなる。
このため、金属光輝層からなるエンブレムが映えなくなり、意匠性（高級感等）が向上しないという問題がある。 However, the above-described radome has a problem that light is reflected not only on the metallic luminous surface but also around the metallic luminous surface when viewed from the front (vehicle outer side). That is, since the entire surface of the radome exhibits a sense of gloss, the contrast between the metallic bright surface and the periphery thereof becomes low.
For this reason, there exists a problem that the emblem which consists of a metallic lustrous layer can not be reflected, and design nature (a high-class feeling etc.) does not improve.

本発明は、装飾部の周囲の光沢を調整して、装飾部の意匠性を向上させることができる車両用装着品を提供することを目的とする。   An object of the present invention is to provide a vehicle attachment that can adjust the gloss around the decorative portion to improve the design of the decorative portion.

It melt | dissolves and it is characterized by welding and joining the said transparent member and the said base member .

本発明に係る車両用装着品の第二実施態様は、第一実施態様において、前記接触面は、表面粗さＲａが１０μｍ以上３０μｍ以下の粗面に形成されることを特徴とする。 A second embodiment of the vehicle attachment according to the present invention is characterized in that, in the first embodiment, the contact surface is formed as a rough surface having a surface roughness Ra of 10 μm to 30 μm.

本発明に係る車両用装着品の第五実施態様は、第一から第三実施態様のいずれかにおいて、前記透明部材は、前記装飾部が配置される領域に凹部を有し、前記ベース部材は、前記凹部を満たす凸部を有することを特徴とする。 In a fifth embodiment of the vehicle attachment according to the present invention, in any of the first to third embodiments, the transparent member has a recess in a region where the decorative portion is disposed, and the base member is And a convex portion filling the concave portion.

本発明に係る車両用装着品は、透明部材の後面のうち、装飾部が配置される領域を除く接触面が粗面化されるので、接触面における光の反射を抑制することができる。このため、装飾部とその周囲（接触面）のコントラストが高くなり、装飾部が映えるようになる。したがって、車両用装着品の意匠性を向上させることができる。   In the vehicle attachment according to the present invention, since the contact surface of the rear surface of the transparent member excluding the area where the decorative portion is disposed is roughened, it is possible to suppress the reflection of light on the contact surface. As a result, the contrast between the decorative portion and the periphery (contact surface) becomes high, and the decorative portion appears. Accordingly, the design of the vehicle attachment can be improved.

〔第一実施形態〕
第一実施形態に係るレドーム１０の構成を図１から図３を参照して説明する。

The configuration of the radome 10 according to the first embodiment will be described with reference to FIGS. 1 to 3.
FIG. 1 is a front view of the radome 10 and the radiator grille 1 according to the first embodiment, and shows (a) the radiator grille 1 and (b) the radome 10.
FIG. 2 is a cross-sectional view of the radome 10 (II-II cross section of FIG. 1 (b)).
FIG. 3 is a cross-sectional view of (a) the transparent member 11, (b) the glitter member 13, and (c) the base member 16.

各図面において、矢印は、車両Ａの前方Ｆを示す。
レドーム１０のうち、車外側（前方Ｆ）を向く面を前面と呼ぶ。車内側（車両Ａの後方）を向く面を後面と呼ぶ。 In each drawing, the arrow indicates the front F of the vehicle A.
The surface of the radome 10 facing the vehicle outside (front F) is called the front. The surface facing the inside of the vehicle (the rear of the vehicle A) is called the rear surface.

レドーム（車両用装着品）１０は、車両Ａに装着される樹脂成型品であって、車両Ａの前面に露出する。レドーム１０は、電波を用いて車両Ａの周囲の障害物を検知するために車両Ａに搭載されたレーダ２の検知側（前方側）に配置される。   The radome (vehicle attachment) 10 is a resin molded article attached to the vehicle A, and is exposed on the front of the vehicle A. The radome 10 is disposed on the detection side (front side) of the radar 2 mounted on the vehicle A in order to detect an obstacle around the vehicle A using radio waves.

ラジエータグリル１は、車両Ａの前面に配置される車両用装着品であり、水平方向（車両Ａの幅方向）に延びる複数の梁状部材と、垂直方向に延びる複数の柱状部材が一体的に成形される。
ラジエータグリル１は、車両Ａの幅方向の中央にレドーム１０を備える。レドーム１０の後方側には、レーダ２が設置される。 The radiator grille 1 is a vehicle mounting member disposed on the front of the vehicle A, and a plurality of beam members extending in the horizontal direction (the width direction of the vehicle A) and a plurality of columnar members extending in the vertical direction are integrated. It is molded.
The radiator grille 1 includes a radome 10 at the center of the vehicle A in the width direction. The radar 2 is installed on the rear side of the radome 10.

レーダ２は、電波を用いて車両Ａの周囲に存在する障害物を検知する装置である。具体的には、レーダ２は、車両Ａと障害物の距離や相対速度等を計測する。
レーダ２は、車間距離検知用レーダの適用周波数である７６ＧＨｚ〜７７ＧＨｚの電波（ミリ波）を出射する発信部と、障害物からの反射電波を受信する受信部とを備える。
レーダ２が出射した電波がレドーム１０を透過すると電波の減衰が生じる。このため、レーダ２が安定して動作して車両Ａと障害物の距離等を正しく計測するために、透過時における減衰をできるだけ低く抑える必要がある。 The radar 2 is a device that detects an obstacle present around the vehicle A using radio waves. Specifically, the radar 2 measures the distance between the vehicle A and the obstacle, the relative velocity, and the like.
The radar 2 includes a transmitter configured to emit a 76 GHz to 77 GHz radio wave (millimeter wave), which is an applied frequency of the inter-vehicle distance detection radar, and a receiver configured to receive a reflected radio wave from an obstacle.
When the radio wave emitted by the radar 2 passes through the radome 10, attenuation of the radio wave occurs. For this reason, in order to operate the radar 2 stably and measure the distance between the vehicle A and the obstacle correctly, it is necessary to suppress the attenuation at the time of transmission as low as possible.

レドーム１０は、レーダ２の前方側を覆って保護する部材であって、略矩形板状に形成された樹脂成形品である。
レドーム１０は、前方側から見ると、金属光輝性を呈する金属光輝部１０Ｍと、黒色等の色を呈する有色部１０Ｐを有する。
金属光輝部１０Ｍは、レドーム１０の内部に二箇所設けられ、互いに水平方向に沿って平行に延在する。この二つの金属光輝部１０Ｍによって、車両Ａの標章であるエンブレムＭが表される。
有色部１０Ｐは、金属光輝部１０Ｍの周囲の領域に、金属光輝部１０Ｍを取り囲むように設けられる。 The radome 10 is a member that covers and protects the front side of the radar 2 and is a resin molded product formed in a substantially rectangular plate shape.
The radome 10, as viewed from the front side, has a metallic glittering portion 10M exhibiting metallic luster and a colored portion 10P exhibiting a color such as black.
The metallic bright portions 10M are provided at two locations inside the radome 10, and extend in parallel along the horizontal direction. An emblem M, which is a mark of the vehicle A, is represented by the two metallic bright portions 10M.
The colored portion 10P is provided in a region around the metallic glitter portion 10M so as to surround the metallic glitter portion 10M.

レドーム１０は、透明部材１１、光輝部材１３およびベース部材１６を備える。
透明部材１１は、前方側から見ると、略矩形板状の部材であり、例えばＰＣ（ポリカーボネート）やＰＭＭＡ（ポリメタクリル酸メチル樹脂）等の透明な合成樹脂からなる。
透明部材１１は、車両Ａの前後方向の厚みが、１．５ｍｍから１０ｍｍ程度に形成される。 The radome 10 comprises a transparent member 11, a bright member 13 and a base member 16.
The transparent member 11 is a substantially rectangular plate-like member when viewed from the front side, and is made of a transparent synthetic resin such as PC (polycarbonate) or PMMA (polymethyl methacrylate resin).
The transparent member 11 is formed to have a thickness in the front-rear direction of the vehicle A of about 1.5 mm to 10 mm.

透明部材１１の前面１１ａには、傷付き防止のために、ハードコート処理またはウレタン系塗料のクリヤーコート処理が施される。透明合成樹脂が耐傷付き性を有する場合であれば、これらの傷付き防止処理は不要である。
透明部材１１の後面１１ｂのうち、金属光輝部１０Ｍに対応する領域には、凹部１２が形成される。この凹部１２は、光輝部材１３を収容する部位である。 The front surface 11 a of the transparent member 11 is subjected to a hard coating process or a clear coating process of a urethane-based paint in order to prevent damage. If the transparent synthetic resin has scratch resistance, these scratch prevention processes are unnecessary.
A concave portion 12 is formed in a region corresponding to the metallic bright portion 10M in the rear surface 11b of the transparent member 11. The recess 12 is a portion for accommodating the glitter member 13.

透明部材１１の後面１１ｂのうち、凹部１２を除く領域は、平坦な面に形成される。この平坦な面は、有色部１０Ｐに対応する非装飾面１１ｃであり、粗面に形成される。非装飾面１１ｃの表面粗さＲａは、１０μｍ以上、３０μｍ以下に設定される。
非装飾面（接触面）１１ｃは、全域に亘って均一な表面粗さに形成される。 An area of the rear surface 11 b of the transparent member 11 excluding the recess 12 is formed to be a flat surface. This flat surface is the non-decorative surface 11c corresponding to the colored portion 10P, and is formed rough. The surface roughness Ra of the non-decorative surface 11c is set to 10 μm or more and 30 μm or less.
The non-decorative surface (contact surface) 11c is formed to have a uniform surface roughness over the entire area.

光輝部材（装飾部）１３は、凹部１２を満たす形状に成形されて、凹部１２に収容（配置）される部材である。
光輝部材１３は、凹部１２を満たす光輝部材本体１４と、光輝部材本体１４の前面に配置された金属光輝層１５を有する。
金属光輝層１５は、金属光輝性を呈し、透明部材１１の凹部１２に接する前面１３ａとなる。また、金属光輝層１５は、レドーム１０を前方側から見たときに、立体的に視認される金属光輝部１０Ｍとなる。 The glittering member (decorative portion) 13 is a member that is formed into a shape that fills the recess 12 and is accommodated (disposed) in the recess 12.
The bright member 13 has a bright member main body 14 that fills the recess 12 and a metallic bright layer 15 disposed on the front surface of the bright member main body 14.
The metallic glitter layer 15 exhibits metallic luster and serves as the front surface 13 a in contact with the recess 12 of the transparent member 11. Further, the metallic glittering layer 15 becomes the metallic glittering part 10M which is three-dimensionally recognized when the radome 10 is viewed from the front side.

光輝部材本体１４は、例えばＡＢＳ（アクリロニトリル・ブタジエン・スチレン共重合合成樹脂）、ＰＣ又はＰＥＴ（ポリエチレンテレフタレート）等の合成樹脂からなる。
光輝部材本体１４は、凹部１２に収容（配置）されたときに、透明部材１１の後面１１ｂ（非装飾面１１ｃ）と略面一となる形状を有する。 The bright member main body 14 is made of, for example, a synthetic resin such as ABS (acrylonitrile butadiene styrene copolymer synthetic resin), PC or PET (polyethylene terephthalate).
The glitter member main body 14 has a shape that is substantially flush with the rear surface 11 b (non-decorative surface 11 c) of the transparent member 11 when housed (arranged) in the recess 12.

金属光輝層１５は、金属蒸着処理を用いて形成された金属層と、この金属層を保護するためのベースコート層及びトップコート層（いずれも不図示）を有する。
蒸着処理としては、真空蒸着法やスパッタリングが用いられる。蒸着される金属としては、インジウム、アルミ又は錫等が使用される。
ベースコート層及びトップコート層は、蒸着処理によって形成され、薄く脆い金属層を保護する。ベースコート層及びトップコート層は、透明（着色透明を含む）な合成樹脂を用いたクリヤー塗装によって形成される。
金属光輝層１５の金属層は非常に薄く、レーダ２が障害物を検知するに十分な電波透過性能を有する。 The metallic bright layer 15 has a metal layer formed by using a metal deposition process, and a base coat layer and a top coat layer (both not shown) for protecting the metal layer.
A vacuum deposition method or sputtering is used as the deposition process. Indium, aluminum, tin or the like is used as the metal to be deposited.
The base coat layer and the top coat layer are formed by vapor deposition to protect the thin and brittle metal layer. The base coat layer and the top coat layer are formed by clear coating using a transparent (including colored and transparent) synthetic resin.
The metal layer of the metallic bright layer 15 is very thin, and has a radio wave transmission performance sufficient for the radar 2 to detect an obstacle.

ベース部材１６は、透明部材１１の後面１１ｂを覆い、透明部材１１と光輝部材１３を一体的に保持する部材である。また、ベース部材１６は、ラジエータグリル１への取り付けに用いられる部材でもあり、複数の取付片１７が後方に向けて突設される。
ベース部材１６は、例えばＡＢＳ、ＡＥＳ（アクリロニトリル・エチレン・スチレン共重合合成樹脂）、ＰＢＴ（ポリブチレンテレフタレート）、ＰＣ、ＰＥＴ等の合成樹脂またはこれらの複合樹脂からなる。
ベース部材１６は、車両Ａの前後方向の厚みが、０．５ｍｍ〜１０ｍｍ程度に形成される。 The base member 16 is a member which covers the rear surface 11 b of the transparent member 11 and integrally holds the transparent member 11 and the glitter member 13. Moreover, the base member 16 is also a member used for attachment to the radiator grille 1, and a plurality of mounting pieces 17 are protruded rearward.
The base member 16 is made of, for example, a synthetic resin such as ABS, AES (acrylonitrile-ethylene-styrene copolymer synthetic resin), PBT (polybutylene terephthalate), PC, PET, or a composite resin thereof.
The base member 16 is formed to have a thickness in the front-rear direction of the vehicle A of about 0.5 mm to 10 mm.

ベース部材１６の前面１６ａは、平滑に形成され、透明部材１１の後面１１ｂ（非装飾面１１ｃ）と光輝部材１３（光輝部材本体１４）の後面１３ｂに密着配置される。
ベース部材１６は、例えば黒色等の有色であり、レドーム１０を前方側から見たときに、透明部材１１を介して視認される。つまり、ベース部材１６の前面１６ａのうち、透明部材１１に接触する視認面（１６ｃは、金属光輝部１０Ｍの周囲の領域、すなわち有色部１０Ｐとなる。
視認面（接触面）１６ｃは、透明部材１１の非装飾面１１ｃに密着配置されることにより、非装飾面１１ｃに倣って粗面化する。 The front surface 16 a of the base member 16 is formed to be smooth, and is disposed in close contact with the rear surface 11 b (non-decorative surface 11 c) of the transparent member 11 and the rear surface 13 b of the glitter member 13 (glitter member body 14).
The base member 16 is colored, for example, black, and is viewed through the transparent member 11 when the radome 10 is viewed from the front side. That is, of the front surface 16 a of the base member 16, the viewing surface (16 c in contact with the transparent member 11 becomes an area around the metallic bright portion 10 M, that is, the colored portion 10 P.
The visual recognition surface (contact surface) 16 c is arranged in close contact with the non-decorative surface 11 c of the transparent member 11 so as to be roughened in accordance with the non-decorative surface 11 c.

次に、第一実施形態に係るレドーム１０の製造方法を図４を参照して説明する。
図４は、第一実施形態に係るレドーム１０の製造方法を示す概略図である。 Next, a method of manufacturing the radome 10 according to the first embodiment will be described with reference to FIG.
FIG. 4 is a schematic view showing a method of manufacturing the radome 10 according to the first embodiment.

レドーム１０の製造方法は、透明部材１１を成形する第一工程、光輝部材１３を成形する第二工程と、光輝部材１３を凹部１２に配置する第三工程、透明部材１１の後面１１ｂにベース部材１６を一体成形する第四工程を有する。
以下、各工程について説明する。 In the method of manufacturing the radome 10, the first step of molding the transparent member 11, the second step of molding the glitter member 13, the third step of arranging the glitter member 13 in the recess 12, the base member on the rear surface 11b of the transparent member 11 It has the 4th process of forming 16 integrally.
Each step will be described below.

第一工程では、図４（ａ）に示すように、透明部材１１を成形する。
透明部材１１を射出成形によって成形し、その後面１１ｂには凹部１２を形成する。
透明部材１１の前面１１ａは、滑面に形成される。同様に、後面１１ｂのうち、凹部１２の内面は、滑面に形成される。
透明部材１１の前面１１ａには、ハードコート処理が施される。 In the first step, as shown in FIG. 4A, the transparent member 11 is formed.
The transparent member 11 is formed by injection molding, and a recess 12 is formed on the rear surface 11 b.
The front surface 11 a of the transparent member 11 is formed to be a smooth surface. Similarly, of the rear surface 11b, the inner surface of the recess 12 is formed as a smooth surface.
The front surface 11 a of the transparent member 11 is subjected to a hard coating process.

一方、後面１１ｂのうち、非装飾面１１ｃは、粗面に形成される。非装飾面１１ｃは、成形金型に形成した粗面が転写される。つまり、成形金型のキャビティ空間の内面（金型面）のうち、非装飾面１１ｃを成形する面は、表面粗さＲａが１０μｍ以上３０μｍ以下に設定される。非装飾面１１ｃを成形する面は、例えば、ショットブラスト処理により粗面化される。
このため、非装飾面１１ｃは、成形時に、粗面化された金型面に倣って粗面に形成される。 On the other hand, of the rear surface 11b, the non-decorative surface 11c is roughened. The rough surface formed on the molding die is transferred to the non-decorative surface 11c. That is, of the inner surface (mold surface) of the cavity space of the molding die, the surface on which the non-decorative surface 11c is molded is set to have a surface roughness Ra of 10 μm to 30 μm. The surface for forming the non-decorative surface 11c is roughened by, for example, shot blasting.
For this reason, the non-decorative surface 11c is formed rough according to the roughened mold surface at the time of molding.

次に、第二工程では、図４（ｂ）及び（ｃ）に示すように、光輝部材１３を成形する。
光輝部材本体１４を射出成形によって成形した後に、光輝部材本体１４の前面に金属光輝層１５を配置（形成）する。
金属光輝層１５は、ベースコート層、金属層及びトップコート層を光輝部材本体１４に対して順に積層することによって形成される。ベースコート層及びトップコート層は、透明合成樹脂を用いたクリヤー塗装によって形成され、金属層は、金属蒸着処理により形成される。 Next, in the second step, as shown in FIGS. 4B and 4C, the glitter member 13 is formed.
After the glitter member body 14 is formed by injection molding, the metallic glitter layer 15 is disposed (formed) on the front surface of the glitter member body 14.
The metallic glitter layer 15 is formed by sequentially laminating a base coat layer, a metal layer and a top coat layer on the glitter member main body 14. The base coat layer and the top coat layer are formed by clear coating using a transparent synthetic resin, and the metal layer is formed by metal vapor deposition treatment.

第一工程と第二工程は、並行して実施することができる。このため、レドーム１０の製造に要する時間を短縮することができる。   The first and second steps can be performed in parallel. For this reason, the time which manufacture of radome 10 can be shortened.

次に、第三工程では、図４（ｄ）に示すように、光輝部材１３を凹部１２に収容（配置）する。
透明部材１１の凹部１２に光輝部材１３を配置するとき、光輝部材１３の前面１３ａを凹部１２の内面に隙間なく接触させる。 Next, in the third step, as shown in FIG. 4D, the glitter member 13 is housed (arranged) in the recess 12.
When the glittering member 13 is disposed in the recess 12 of the transparent member 11, the front surface 13 a of the glittering member 13 is brought into contact with the inner surface of the recess 12 without any gap.

最後に、第四工程では、図４（ｅ）に示すように、ベース部材１６を成形する。
ベース部材１６は、透明部材１１と光輝部材１３に対してインサート成形される。すなわち、凹部１２に光輝部材１３が配置された透明部材１１を射出成形用金型のキャビティ空間に配置する。その後に、透明部材１１と光輝部材１３の後面１１ｂ，１３ｂに向けて溶融樹脂を射出して、ベース部材１６を成形する。
ベース部材１６は、透明部材１１と光輝部材１３の後面１１ｂ，１３ｂの全域を覆うため、透明部材１１と光輝部材１３を一体的に保持することができる。
ベース部材１６の前面１６ａのうち、透明部材１１に接触する視認面１６ｃは、透明部材１１の非装飾面１１ｃに密着して粗面化する。 Finally, in the fourth step, as shown in FIG. 4E, the base member 16 is formed.
The base member 16 is insert-molded to the transparent member 11 and the bright member 13. That is, the transparent member 11 in which the glitter member 13 is disposed in the recess 12 is disposed in the cavity space of the injection molding die. Thereafter, the molten resin is injected toward the rear surfaces 11 b and 13 b of the transparent member 11 and the glitter member 13 to form the base member 16.
Since the base member 16 covers the entire area of the transparent member 11 and the rear surfaces 11 b and 13 b of the glitter member 13, the transparent member 11 and the glitter member 13 can be integrally held.
Of the front surface 16 a of the base member 16, the viewing surface 16 c in contact with the transparent member 11 is in close contact with the non-decorative surface 11 c of the transparent member 11 and is roughened.

ベース部材１６のインサート成形の際には、溶融樹脂の熱により透明部材１１と光輝部材１３が僅かに溶解する。このため、ベース部材１６は、透明部材１１と光輝部材１３に対して溶着される。したがって、接着剤等を用いなくとも、透明部材１１、光輝部材１３およびベース部材１６を接合させることができる。
このようにして、レドーム１０の製造が完了する。 At the time of insert molding of the base member 16, the transparent member 11 and the bright member 13 are slightly melted by the heat of the molten resin. For this reason, the base member 16 is welded to the transparent member 11 and the bright member 13. Therefore, the transparent member 11, the bright member 13 and the base member 16 can be joined without using an adhesive or the like.
Thus, the production of radome 10 is completed.

第一実施形態に係るレドーム１０は、透明部材１１とベース部材１６が密着する接触面（非装飾面１１ｃ、視認面１６ｃ）が粗面に形成される。このため、レドーム１０を前方側から見たときに、有色部１０Ｐの光沢が抑制される。
有色部１０Ｐは、透明部材１１を介してベース部材１６の前面１６ａ（視認面１６ｃ）を視認したものである。このとき、透明部材１１の非装飾面１１ｃとベース部材１６の視認面１６ｃが粗面化されているため、レドーム１０の前面から入射した光が非装飾面１１ｃと視認面１６ｃで乱反射する。具体的には、透明部材１１を前方側から見たときに、非装飾面１１ｃが白濁したようになる。
このため、非装飾面１１ｃに密着するベース部材１６の前面１６ａ（視認面１６ｃ）の光沢が抑制される。つまり、レドーム１０は、前方側から見たときに、有色部１０Ｐの光沢が抑制される一方で、金属光輝部１０Ｍの光沢は維持される。したがって、金属光輝部１０Ｍと有色部１０Ｐのコントラストが高くなる。
よって、金属光輝部１０ＭであるエンブレムＭが映えるようになり、レドーム１０（エンブレムＭ）の高級感や質感等の意匠性が向上する。 In the radome 10 according to the first embodiment, the contact surfaces (non-decorative surface 11c, visual surface 16c) with which the transparent member 11 and the base member 16 are in close contact are formed to be rough surfaces. Therefore, when the radome 10 is viewed from the front side, the gloss of the colored portion 10P is suppressed.
The colored portion 10P is obtained by visually recognizing the front surface 16a (visual surface 16c) of the base member 16 through the transparent member 11. At this time, since the non-decorative surface 11c of the transparent member 11 and the visible surface 16c of the base member 16 are roughened, light incident from the front surface of the radome 10 is irregularly reflected by the non-decorative surface 11c and the visible surface 16c. Specifically, when the transparent member 11 is viewed from the front side, the non-decorative surface 11 c becomes cloudy.
For this reason, the gloss of the front surface 16a (viewing surface 16c) of the base member 16 in close contact with the non-decorative surface 11c is suppressed. That is, when the radome 10 is viewed from the front side, the gloss of the colored portion 10P is suppressed, while the gloss of the metallic bright portion 10M is maintained. Therefore, the contrast of the metallic bright part 10M and the colored part 10P becomes high.
Therefore, the emblem M which is the metallic bright part 10M comes to shine, and the designability of the radome 10 (emblem M) such as the luxury feeling and the texture is improved.

特に、透明部材１１とベース部材１６が密着する接触面（非装飾面１１ｃ、視認面１６ｃ）の表面粗さＲａを１０μｍ以上３０μｍ以下に設定することにより、有色部１０Ｐの光沢を効果的に抑制できる。つまり、金属光輝部１０Ｍと有色部１０Ｐのコントラストが良好になる。   In particular, the gloss of the colored portion 10P is effectively suppressed by setting the surface roughness Ra of the contact surface (non-decorative surface 11c, visual surface 16c) where the transparent member 11 and the base member 16 adhere to each other to 10 μm to 30 μm. it can. That is, the contrast between the metallic bright portion 10M and the colored portion 10P is improved.

また、非装飾面１１ｃを粗面化する方法として、透明部材１１の成形金型に形成した粗面を転写するようにしたので、製造工程や設備を増加させる必要がない。このため、レドーム１０の製造時間の短縮や製造コストの抑制を図ることができる。   Further, since the rough surface formed on the molding die of the transparent member 11 is transferred as a method of roughening the non-decorative surface 11c, it is not necessary to increase the number of manufacturing processes and equipment. For this reason, shortening of the manufacturing time of the radome 10 and suppression of manufacturing cost can be aimed at.

さらに、透明部材１１とベース部材１６がインサート成形により接合されるので、接着剤等を用いる必要がない。また、製造工程や設備を増加させる必要がないので、レドーム１０の製造時間の短縮や製造コストの抑制を図ることができる。
特に、透明部材１１とベース部材１６の間に隙間が形成されないので、レーダ２から出射されたミリ波が殆ど減衰されることなく、レドーム１０を透過できる。 Furthermore, since the transparent member 11 and the base member 16 are joined by insert molding, it is not necessary to use an adhesive or the like. Further, since it is not necessary to increase the number of manufacturing processes and equipment, the manufacturing time of the radome 10 can be shortened and the manufacturing cost can be suppressed.
In particular, since no gap is formed between the transparent member 11 and the base member 16, the millimeter wave emitted from the radar 2 can be transmitted through the radome 10 with almost no attenuation.

透明部材１１の非装飾面１１ｃは、粗面に形成される。 A metallic glitter layer 55 is formed on the inner surface of the recess 12 of the transparent member 11. The metallic glitter layer (decorative part) 55 has the same layer configuration as the metallic glitter layer 15 in the first embodiment.
The metallic glitter layer 55 becomes the metallic glitter portion 10 M in the same manner as the metallic glitter layer 15, but unlike the metallic glitter layer 15, is formed directly on the inner surface of the recess 12 of the transparent member 11.
The non-decorative surface 11 c of the transparent member 11 is formed to be a rough surface.

レドーム５０の製造方法は、透明部材１１を成形する第一工程、凹部１２の内面に金属光輝層１５を形成する第二工程、透明部材１１の後面１１ｂにベース部材５６を一体成形する第三工程を有する。
第一工程と第三工程は、第一実施形態における製造方法の第一工程と第四工程と同一である。 The method of manufacturing the radome 50 includes a first step of molding the transparent member 11, a second step of forming the metallic glitter layer 15 on the inner surface of the recess 12, and a third step of integrally molding the base member 56 on the rear surface 11b of the transparent member 11. Have.
The first and third steps are the same as the first and fourth steps of the manufacturing method in the first embodiment.

第二実施形態に係るレドーム５０は、第一実施形態に係るレドーム１０と同一の作用効果を奏する。
すなわち、透明部材１１とベース部材５６が密着する接触面（非装飾面１１ｃ、視認面５６ｃ）が粗面に形成されるので、レドーム５０を前方側から見たときに、有色部１０Ｐの光沢が抑制される。つまり、非装飾面１１ｃに密着するベース部材５６の前面５６ａ（視認面（接触面）５６ｃ）の光沢が抑制される。したがって、レドーム５０は、金属光輝部１０Ｍと有色部１０Ｐのコントラストが高くなる。
よって、金属光輝部１０ＭであるエンブレムＭが映えるようになり、レドーム５０（エンブレムＭ）の高級感や質感等の意匠性が向上する。 The radome 50 which concerns on 2nd embodiment has the same effect as the radome 10 which concerns on 1st embodiment.
That is, since the contact surfaces (the non-decorative surface 11c and the visible surface 56c) where the transparent member 11 and the base member 56 are in close contact are formed as rough surfaces, the gloss of the colored portion 10P is when the radome 50 is viewed from the front side. Be suppressed. That is, the gloss of the front surface 56a (visual surface (contact surface) 56c) of the base member 56 in close contact with the non-decorative surface 11c is suppressed.

図６は、本発明の第三実施形態に係るレドーム６０を示す断面図である。
レドーム（車両用装着品）６０は、透明部材６１とベース部材１６を備える。
透明部材６１は、第一および第二実施形態における透明部材１１とは異なって、後面６１ｂが全域に亘って平坦に形成される。つまり、透明部材６１は、後面６１ｂに凹部１２を有しない。 FIG. 6 is a cross-sectional view showing a radome 60 according to a third embodiment of the present invention.
The radome (vehicle attachment) 60 includes a transparent member 61 and a base member 16.
Unlike the transparent member 11 in the first and second embodiments, the transparent member 61 has a rear surface 61 b formed flat over the entire area. That is, the transparent member 61 does not have the recess 12 in the rear surface 61 b.

透明部材６１の後面６１ｂのうち、金属光輝部１０Ｍに対応する領域には、金属光輝層６５が配置（形成）される。
透明部材６１の後面６１ｂのうち、有色部１０Ｐに対応する領域（非装飾面６１ｃ）は、粗面に形成される。非装飾面（接触面）６１ｃは、第一および第二実施形態における非装飾面１１ｃと同一の表面粗さに設定される。 A metallic glitter layer 65 is disposed (formed) in a region corresponding to the metallic glitter portion 10M in the rear surface 61b of the transparent member 61.
In the rear surface 61b of the transparent member 61, a region (non-decorative surface 61c) corresponding to the colored portion 10P is formed to be a rough surface. The non-decorative surface (contact surface) 61c is set to the same surface roughness as the non-decorative surface 11c in the first and second embodiments.

金属光輝層（装飾部）６５は、第一および第二実施形態における金属光輝層１５，５５と同一の層構成を有する。
一方、金属光輝層６５は、金属光輝層１５とは異なって平面状に形成される。このため、レドーム６０を前方側から見たときに、金属光輝部６０Ｍは、平面的に視認される。 The metallic glitter layer (decorative part) 65 has the same layer configuration as the metallic glitter layers 15 and 55 in the first and second embodiments.
On the other hand, unlike the metal glitter layer 15, the metal glitter layer 65 is formed in a planar shape. For this reason, when the radome 60 is viewed from the front side, the metallic bright portion 60M is viewed in a planar manner.

レドーム６０の製造方法は、第二実施形態に係るレドーム５０の製造方法とほぼ同一である。
すなわち、透明部材６１を成形する第一工程、透明部材６１に金属光輝層６５を形成する第二工程、透明部材６１の後面６１ｂにベース部材１６を一体成形する第三工程を有する。 The method of manufacturing the radome 60 is substantially the same as the method of manufacturing the radome 50 according to the second embodiment.
That is, it has a first step of forming the transparent member 61, a second step of forming the metallic glitter layer 65 on the transparent member 61, and a third step of integrally forming the base member 16 on the rear surface 61b of the transparent member 61.

第三実施形態に係るレドーム６０は、第一および第二実施形態に係るレドーム１０，５０と同一の作用効果を奏する。
すなわち、透明部材６１とベース部材１６が密着する接触面（非装飾面６１ｃ、視認面１６ｃ）が粗面に形成されるので、レドーム６０を前方側から見たときに、有色部１０Ｐの光沢が抑制される。つまり、非装飾面６１ｃに密着するベース部材１６の前面１６ａ（視認面１６ｃ）の光沢が抑制される。したがって、レドーム６０は、金属光輝部６０Ｍと有色部１０Ｐのコントラストが高くなる。
よって、金属光輝部６０ＭであるエンブレムＭが映えるようになり、レドーム６０（エンブレムＭ）の高級感や質感等の意匠性が向上する。 The radome 60 which concerns on 3rd embodiment has the effect same as the radome 10 and 50 which concerns on 1st and 2nd embodiment.
That is, since the contact surfaces (non-decorative surface 61c, visual surface 16c) where the transparent member 61 and the base member 16 are in close contact are formed to be rough surfaces, the gloss of the colored portion 10P is when the radome 60 is viewed from the front side. Be suppressed. That is, the gloss of the front surface 16a (visual surface 16c) of the base member 16 in close contact with the non-decorative surface 61c is suppressed. Therefore, in the radome 60, the contrast between the metallic bright part 60M and the colored part 10P is increased.
Therefore, the emblem M which is the metallic bright part 60M comes to be reflected, and the designability of the radome 60 (emblem M) such as the luxury feeling and the texture is improved.

上述した実施の形態において示した各構成部材の諸形状や組み合わせ等は一例であって、本発明の主旨から逸脱しない範囲において設計要求等に基づき種々変更可能である。   The shapes, combinations, and the like of the constituent members shown in the above-described embodiment are merely examples, and various changes can be made based on design requirements and the like without departing from the spirit of the present invention.

金属光輝層１５，６５を金属蒸着処理により形成する場合について説明したが、これに限定されない。
金属光輝層１５，６５は、十分な電波透過性能を持ち、且つ、金属光輝性を有することができる塗装その他の方法によって形成してもよい。 Although the case where the metallic glitter layers 15 and 65 are formed by metal vapor deposition has been described, the present invention is not limited thereto.
The metallic glitter layers 15 and 65 may be formed by painting or other methods that have sufficient radio wave transmission performance and can have metallic glitter.

ベース部材１６，５６をインサート成形によって形成する場合について説明したが、これに限定されない。
ベース部材１６，５６は、いわゆる二色成形（ダブルモールド）やＤＳＩ（Die slide injection）を用いて成形してもよい。このような製造方法によれば、レドーム１０，５０，６０の製造工程を更に短縮することができる。 Although the case where base members 16 and 56 were formed by insert molding was explained, it is not limited to this.
The base members 16 and 56 may be formed by using so-called two-color molding (double mold) or DSI (die slide injection). According to such a manufacturing method, the manufacturing process of the radome 10, 50, 60 can be further shortened.

ベース部材１６，５６を透明部材１１，６１に対してインサート成形する場合について説明したが、これに限定されない。
透明部材１１，６１をベース部材１６，５６に対してインサート成形する場合であってもよい。
この場合には、透明部材１１，６１の非装飾面１１ｃ，６１ｃに代えて、ベース部材１６，５６の視認面１６ｃ，５６ｃを粗面に形成する。透明部材１１，６１の非装飾面１１ｃ，６１ｃは、成形時に、ベース部材１６，５６の視認面１６ｃ，５６ｃに密着配置されることにより、視認面１６ｃ，５６ｃに倣って粗面化する。
このため、レドーム１０，５０，６０を前方側から見たときに、有色部１０Ｐの光沢が抑制される。 Although the case where insert molding of the base members 16 and 56 was carried out with respect to the transparent members 11 and 61 was demonstrated, it is not limited to this.
The transparent members 11 and 61 may be insert-molded on the base members 16 and 56.
In this case, the visible surfaces 16c and 56c of the base members 16 and 56 are roughened instead of the non-decorative surfaces 11c and 61c of the transparent members 11 and 61. The non-decorative surfaces 11c and 61c of the transparent members 11 and 61 are closely arranged on the viewing surfaces 16c and 56c of the base members 16 and 56 at the time of molding, and are roughened to follow the viewing surfaces 16c and 56c.
Therefore, when the radome 10, 50, 60 is viewed from the front side, the gloss of the colored portion 10P is suppressed.

非装飾面１１ｃ，６１ｃや視認面１６ｃ，５６ｃを粗面化する方法として、成形金型に形成した粗面を転写する方法について説明したが、これに限らない。
非装飾面１１ｃ，６１ｃや視認面１６ｃ，５６ｃに対して、直接、粗面化処理を施してもよい。すなわち、非装飾面１１ｃ，６１ｃや視認面１６ｃ，５６ｃにショットブラスト処理等を施してもよい。
粗面化処理は、ショットブラスト処理に限らず、ヘアーライン加工やエッチング処理（化学的処理）等であってもよい。 Although the method of transferring the rough surface formed on the molding die has been described as the method of roughening the non-decorative surfaces 11c and 61c and the visible surfaces 16c and 56c, the present invention is not limited thereto.
The non-decorating surfaces 11c and 61c and the viewing surfaces 16c and 56c may be directly roughened. That is, the non-decorative surfaces 11c and 61c and the viewing surfaces 16c and 56c may be subjected to shot blasting or the like.
The roughening treatment is not limited to the shot blast treatment, but may be hairline processing, etching treatment (chemical treatment) or the like.
