形状が大きくなって見栄えが良くなる。(B. Summary of the Invention) The automobile headlamp of the present invention includes a peripheral light emitting means in the lamp body that illuminates a portion corresponding to the shape difference between the front opening and the projection portion of the lamp body. As a result, the part corresponding to the difference in shape between the front opening of the lamp body and the projection part is also illuminated, and the driver or pedestrian of the preceding vehicle can see the following vehicle or passing vehicle on either side. It can be noted that the vehicle is larger than a passenger car equipped with headlights, and the front shape that can be seen as headlights is enlarged, which improves the appearance.
（Ｃ，従来技術）［第８図］
反射光を前方の集光部に集光させる反射鏡と該反射鏡の
前方に配置されその焦点が前記集光部近傍に位置された
投影レンズとを備えた前照灯がある。(C, Prior Art) [Figure 8] A reflecting mirror that focuses reflected light onto a focusing section in front of it, and a projection lens that is placed in front of the reflecting mirror and whose focal point is located near the focusing section. There is a headlight provided.
このような前照灯はその配光パターンが非常にシャープ
な輪郭を有するので、厳しい配光規格を満足させるのに
好適であり、自動車用の前照灯として優れている。Since such a headlamp has a light distribution pattern with a very sharp outline, it is suitable for satisfying strict light distribution standards and is excellent as a headlamp for automobiles.
しかしながら、このような前照灯はその出光面が非常に
小さいので、デザイン的に大型の前照灯や細長い前照灯
が好まれる傾向にある現在においては、外観的に好まれ
ないという問題がある。However, since the light emitting surface of such headlights is very small, there is a problem that the appearance of these headlights is undesirable at a time when large headlights and elongated headlights tend to be preferred in terms of design. be.
そこで、第８図に示すように、反射光を前方の集光部に

ダミー板ｄに形成した挿通孔ｅに投影部ａの前端部を挿
通した自動車用前照灯ｆが考えられている。Therefore, as shown in FIG. 8, a reflecting mirror for condensing the reflected light onto a condensing section in front, and a projection lens disposed in front of the reflecting mirror, the focal point of which is located near the condensing section, are provided. The projected portion a is placed in a lamp body b with a larger outline, especially a larger front opening, as a projection part, the front opening of the lamp body b is covered with a lens C, and the front opening is placed inside the lamp body b. An automobile headlamp f is considered in which a dummy plate d serving as a reflective surface is arranged and a front end of a projection part a is inserted into an insertion hole e formed in the dummy plate d.
このような自動車用前照灯ｆによれば、昼間にあっては

慣れがあり、交通の安全上きわめて問題であるし、また
、見栄えも悪い。(D. Problem to be Solved by the Invention) [Figures 8 and 9] By the way, in the above-mentioned automobile headlight f, the dummy plate d does not shine at night, and only the projection part a shines. Because it appears bright, when drivers or pedestrians in front of you see it, it creates an illusion as if two motorcycles are running side by side, as shown in Figure 9, causing traffic problems. When making decisions, people are accustomed to making incorrect decisions based on incorrect information, which is extremely problematic for traffic safety and also looks bad.
（Ｅ、課題を解決するための手段）
そこで、本発明自動車用前照灯は、上記した課題を解決
するために、投影部の前端部とランプボディの前面開口

Means for Solving the Problems) Therefore, in order to solve the above-mentioned problems, the automobile headlamp of the present invention addresses the difference in shape between the front end of the projection part and the front opening of the lamp body. It has a peripheral light emitting means that makes the corresponding part shine.
従りて、本発明自動車用前照灯にあっては、周辺部発光
手段によって、ランプボディの前面開口部と投影部との
