On the other hand, the light 38 incident on the second projecting portion 54 from each LED light source 22 is guided backward while being irregularly reflected in the second projecting portion 54, and irradiated rearward from the rear end portion 58. Each of the rear end portions 56 and 58 is viewed as a light guide surface of the light 38 in which a plurality of rectangular blocks are arranged in a substantially M shape in the rear view of FIG. 3, while in the side view of FIG. Each block is visually recognized as a step-like structure.

第１突出部５２内で乱反射しながら導光される光３８の一部は、第２突出部５４に対向する第１透過面６０を透過して側方に照射される。また、第２突出部５４内で乱反射しながら導光される光３８の一部は、第１突出部５２に対向する第２透過面６２を透過して側方に照射される。 A part of the light 38 guided while being irregularly reflected in the first protrusion 52 is transmitted to the side through the first transmission surface 60 facing the second protrusion 54. Further, a part of the light 38 guided while being irregularly reflected in the second projecting portion 54 passes through the second transmission surface 62 facing the first projecting portion 52 and is irradiated to the side.

ここで、第１突出部５２及び第２突出部５４は、図４の側面視で、前方側が重なり合っている。また、図４の側面視及び図８の断面視で示すように、第１突出部５２の後方端部５６側は、第２突出部５４の後方端部５８のうち、第１突出部５２の後方端部５６に重なり合う部分よりも後方に延出している。そのため、第２突出部５４内を導光して第２透過面６２を透過した光３８は、第１突出部５２の第１透過面６０で反射され、自動二輪車１２の左右方向に照射される。 Here, as for the 1st protrusion part 52 and the 2nd protrusion part 54, the front side has overlapped by the side view of FIG. Further, as shown in a side view of FIG. 4 and a cross-sectional view of FIG. 8, the rear end 56 side of the first protrusion 52 is the rear end 58 of the second protrusion 54. It extends rearward from the portion overlapping the rear end portion 56. Therefore, the light 38 guided through the second projecting portion 54 and transmitted through the second transmitting surface 62 is reflected by the first transmitting surface 60 of the first projecting portion 52 and irradiated in the left-right direction of the motorcycle 12. .

図５及び図６に示すように、第１突出部５２の下面６４における後方端部５６近傍には、下方に向かって突出する規制部６６が形成され、一方で、第２突出部５４の上面６８における後方端部５８近傍には、上方に向かって突出する規制部７０が形成されている。なお、図７及び図８に示すように、規制部６６は、第１突出部５２の左右にも設けられると共に、規制部７０は、第２突出部５４の左右にも設けられている。 As shown in FIGS. 5 and 6, a restricting portion 66 protruding downward is formed in the vicinity of the rear end portion 56 on the lower surface 64 of the first protruding portion 52, while the upper surface of the second protruding portion 54 is formed. In the vicinity of the rear end portion 58 of 68, a restricting portion 70 protruding upward is formed. As shown in FIGS. 7 and 8, the restricting portion 66 is also provided on the left and right sides of the first projecting portion 52, and the restricting portion 70 is also provided on the left and right sides of the second projecting portion 54.

前述した枠部４６は、光３８に対して不透過の部材、又は、光３８に対して透過性の低い部材で形成され、枠部４６の開口部分を画成する略Ｍ字状の内縁部分が規制部６６、７０と係合することにより、当該開口部分にインナーレンズ４４が嵌め込まれる。 The frame portion 46 described above is formed of a member that is opaque to the light 38 or a member that is low in transmittance with respect to the light 38, and is a substantially M-shaped inner edge portion that defines the opening portion of the frame portion 46. Engages with the restricting portions 66 and 70, so that the inner lens 44 is fitted into the opening.

具体的に、枠部４６の内縁部分のうち、第１突出部５２に対向する部分は、規制部６６と係合することにより、下面６４における規制部６６の後方で第１突出部５２に沿う枠壁部７２として形成される。一方、枠部４６の内縁部分のうち、第２突出部５４に対向する部分は、規制部７０と係合することにより、上面６８における規制部７０の後方で第２突出部５４に沿う枠壁部７４として形成される。 Specifically, of the inner edge portion of the frame portion 46, the portion facing the first protruding portion 52 is engaged with the restricting portion 66, thereby being along the first protruding portion 52 behind the restricting portion 66 on the lower surface 64. It is formed as a frame wall portion 72. On the other hand, a portion of the inner edge portion of the frame portion 46 that opposes the second projecting portion 54 engages with the restricting portion 70, so that the frame wall along the second projecting portion 54 is behind the restricting portion 70 on the upper surface 68. Formed as portion 74.

すなわち、枠壁部７２が規制部６６に係合すると共に、枠壁部７４が規制部７０に係合することにより、枠部４６がインナーレンズ４４に対して所定位置に規制された状態で、インナーレンズ４４及び枠部４６が一体的に構成される。従って、第１突出部５２内で導光される光３８の一部が下面６４を透過し、あるいは、第２突出部５４内で導光される光３８の一部が上面６８を透過しても、枠壁部７２、７４を含む枠部４６によって、インナーレンズ４４よりも上下及び左右の場所（インナーレンズ４４以外の場所）で光３８が漏れ出すことを阻止することができる。 That is, while the frame wall portion 72 is engaged with the restricting portion 66 and the frame wall portion 74 is engaged with the restricting portion 70, the frame portion 46 is restricted at a predetermined position with respect to the inner lens 44. The inner lens 44 and the frame portion 46 are integrally formed. Accordingly, a part of the light 38 guided in the first protrusion 52 transmits the lower surface 64, or a part of the light 38 guided in the second protrusion 54 transmits the upper surface 68. In addition, the frame portion 46 including the frame wall portions 72 and 74 can prevent the light 38 from leaking out from the inner lens 44 in the vertical and horizontal locations (locations other than the inner lens 44).

なお、規制部６６、７０の後方で枠壁部７２、７４が係合することにより、枠部４６が前方に変位することを阻止することができる。 In addition, when the frame wall parts 72 and 74 are engaged behind the restricting parts 66 and 70, the frame part 46 can be prevented from being displaced forward.

図４、図７及び図８に示すように、ハウジング２６の左右両側には、光源２４Ｌ、２４Ｒからの光を透過するアウターレンズ７６Ｌ、７６Ｒが、各凹部４０Ｌ、４０Ｒを後方から覆うように取り付けられている。また、ハウジング２６の中央部分には、アウターレンズ７６Ｌ、７６Ｒに連なり、且つ、各ＬＥＤ光源２２からの光３８を透過するアウターレンズ７８が、凹部３０内に配置された各ＬＥＤ光源２２、基板２８及びインナーレンズ４４及び枠部４６を後方から覆うように取り付けられている。 As shown in FIGS. 4, 7, and 8, outer lenses 76 L and 76 R that transmit light from the light sources 24 L and 24 R are attached to the left and right sides of the housing 26 so as to cover the recesses 40 L and 40 R from the rear. It has been. Further, in the central portion of the housing 26, an outer lens 78 connected to the outer lenses 76L and 76R and transmitting the light 38 from each LED light source 22 is disposed in each recess 30 and the substrate 28. The inner lens 44 and the frame 46 are attached so as to cover the rear.

この場合、第１突出部５２の後方端部５６と、第２突出部５４の後方端部５８とが、アウターレンズ７８の前面近傍まで延在するように、アウターレンズ７８がハウジング２６に取り付けられている。 In this case, the outer lens 78 is attached to the housing 26 so that the rear end 56 of the first protrusion 52 and the rear end 58 of the second protrusion 54 extend to the vicinity of the front surface of the outer lens 78. ing.

［本実施形態の効果］
以上説明したように、本実施形態に係るリアコンビネーションランプ１０によれば、各ＬＥＤ光源２２からの光３８に対して不透過の部材、又は、光３８に対して透過性の低い部材で形成される枠部４６によってインナーレンズ４４を囲い、自動二輪車１２の後方に向かって延びる第１突出部５２及び第２突出部５４に沿って枠壁部７２、７４が設けられている。そのため、インナーレンズ４４よりも上下及び左右の箇所で光３８が漏れ出すことを阻止することができる。 [Effect of this embodiment]
As described above, the rear combination lamp 10 according to the present embodiment is formed of a member that is opaque to the light 38 from each LED light source 22 or a member that is low in transparency to the light 38. The frame portion 46 surrounds the inner lens 44, and frame wall portions 72 and 74 are provided along the first protrusion 52 and the second protrusion 54 that extend toward the rear of the motorcycle 12. Therefore, it is possible to prevent the light 38 from leaking out from the inner lens 44 at the upper and lower and left and right positions.

従って、光３８を第１突出部５２及び第２突出部５４内で導光し、後方端部５６、５８から後方に透過させた場合、後方端部５６、５８から後方に照射される光３８は、後方からリアコンビネーションランプ１０を見たときに、インナーレンズ４４の輪郭に沿った光３８となって視認される。すなわち、第１突出部５２及び第２突出部５４の形状通りの光３８を後方に照射するエッジ効果が得られる。 Therefore, when the light 38 is guided in the first projecting portion 52 and the second projecting portion 54 and transmitted rearward from the rear end portions 56 and 58, the light 38 irradiated rearward from the rear end portions 56 and 58. Is viewed as light 38 along the contour of the inner lens 44 when the rear combination lamp 10 is viewed from behind. That is, an edge effect is obtained in which the light 38 having the shape of the first protrusion 52 and the second protrusion 54 is irradiated backward.

このように、本実施形態に係るリアコンビネーションランプ１０によれば、自動二輪車１２の後方からの被視認性を向上させることができる。 Thus, according to the rear combination lamp 10 which concerns on this embodiment, the visibility from the back of the motorcycle 12 can be improved.

また、第１突出部５２における枠壁部７２に対向する下面６４とは反対側の第１透過面６０と、第２突出部５４における枠壁部７４に対向する上面６８とは反対側の第２透過面６２とを、自動二輪車１２の左右方向に光３８を透過させる透過面として形成することにより、自動二輪車１２の側方からのリアコンビネーションランプ１０の被視認性を高めることができる。 Further, the first transmissive surface 60 opposite to the lower surface 64 facing the frame wall portion 72 in the first projecting portion 52 and the first transmissive surface opposite to the upper surface 68 facing the frame wall portion 74 in the second projecting portion 54. The visibility of the rear combination lamp 10 from the side of the motorcycle 12 can be enhanced by forming the two transmission surfaces 62 as transmission surfaces that transmit the light 38 in the left-right direction of the motorcycle 12.

さらに、第２突出部５４は、図３の背面視で、第１突出部５２を外側から囲うように形成されているので、第１突出部５２及び第２突出部５４の両方の形状に沿って、後方に光３８を照射すれば、後方からの被視認性をさらに向上させることができる。 Furthermore, since the 2nd protrusion part 54 is formed so that the 1st protrusion part 52 may be enclosed from the outer side in the rear view of FIG. 3, it follows the shape of both the 1st protrusion part 52 and the 2nd protrusion part 54. If the light 38 is irradiated backward, the visibility from the rear can be further improved.

さらにまた、各ＬＥＤ光源２２からの光３８を、第１突出部５２及び第２突出部５４の間からフレネルレンズとして機能する接続透過部５０を通して、後方に照射することにより、後方からの被視認性を一層向上させることができる。 Furthermore, the light 38 from each LED light source 22 is irradiated rearward from between the first projecting portion 52 and the second projecting portion 54 through the connection transmission portion 50 functioning as a Fresnel lens, so that it is viewed from the rear. Property can be further improved.

また、図４及び図８に示すように、第１透過面６０と第２透過面６２とが互いに対向する領域では、第１突出部５２の後方端部５６側が、第２突出部５４の後方端部５８よりも後方に突出しているので、第２透過面６２を透過した光３８は、第１透過面６０で自動二輪車１２の左右方向に反射する。これにより、自動二輪車１２の側方からの被視認性をさらに高めることができる。 As shown in FIGS. 4 and 8, in the region where the first transmission surface 60 and the second transmission surface 62 face each other, the rear end portion 56 side of the first projection portion 52 is behind the second projection portion 54. Since it protrudes rearward from the end portion 58, the light 38 that has passed through the second transmission surface 62 is reflected by the first transmission surface 60 in the left-right direction of the motorcycle 12. Thereby, the visibility from the side of the motorcycle 12 can be further enhanced.

また、枠部４６が第１突出部５２及び第２突出部５４を一体に囲っていることにより、後方端部５６、５８から後方に照射される光３８を後方から見たとき、インナーレンズ４４の輪郭に沿った光３８となって視認される。これにより、自動二輪車１２の後方からの被視認性を一層向上させることができる。 Further, since the frame 46 integrally surrounds the first protrusion 52 and the second protrusion 54, the inner lens 44 can be seen when the light 38 irradiated rearward from the rear ends 56, 58 is viewed from the rear. It is visually recognized as light 38 along the outline. Thereby, the visibility from the rear of the motorcycle 12 can be further improved.

さらに、後方端部５６、５８の近傍で枠壁部７２、７４を第１突出部５２及び第２突出部５４にそれぞれ沿わせることで、第１突出部５２及び第２突出部５４の形状に沿って自動二輪車１２の後方に光３８を照射することができ、後方からの被視認性をより向上させることができる。 Furthermore, the frame wall portions 72 and 74 are arranged along the first projecting portion 52 and the second projecting portion 54 in the vicinity of the rear end portions 56 and 58, respectively, so that the shape of the first projecting portion 52 and the second projecting portion 54 is obtained. Accordingly, the light 38 can be irradiated to the rear of the motorcycle 12 and the visibility from the rear can be further improved.
