射性能を損う不具合を生じ易かつた。<Prior art> When a metal plate is press-worked to form a reflector body, flanges are formed around the four edges of the front opening of the reflector body. This may increase the strength of the reflector body. However, in a reflector body that consists of flat upper and lower walls and a reflecting surface that extends in a parabolic shape in the left and right directions, the left and right flanges are formed by bending and raising the flanges extending from the left and right edges of the reflecting surface. In this case, the reflective surface is likely to be deformed under the stress, resulting in problems that impair reflective performance.

ランジを形成した事を特徴としたものである。<Means for Solving the Problems> The reflector of the vehicle lamp of the present invention, which achieves the above object, is made by pressing a metal plate and is made of flat upper and lower wall surfaces and a reflecting surface that expands in a parabolic shape in the left and right directions. At the same time, a slit hole is formed between the left and right ends of the reflecting surface and the flange, and the flange is bent toward the front of the front opening of the reflecting mirror body with the slit hole as the center. It is characterized by forming left and right flanges.
〈実施例〉
以下、本考案実施の一例を図面に基づいて説明
する。<Example> Hereinafter, an example of implementing the present invention will be described based on the drawings.
反射鏡本体Ａは、金属板をプレス加工して平ら
な上下壁面A1と左右方向に放物面状に拡がる反
射面A2とからなる偏平形状に成形される。そし
て、反射鏡本体Ａの前面開口部Ｂには、上下壁面
A1に上下フランジ１を形成すると共に、反射面
A2の左右口端A′2に左右フランジ２を形成せしめ
る。 The reflecting mirror main body A is formed by pressing a metal plate into a flat shape consisting of flat upper and lower wall surfaces A 1 and a reflecting surface A 2 that extends in a parabolic shape in the left-right direction. The front opening B of the reflector body A has upper and lower walls.
In addition to forming upper and lower flanges 1 on A 1 , the reflective surface
Left and right flanges 2 are formed at the left and right mouth ends A′ 2 of A 2 .
上下フランジ１及び左右フランジ２は、金属板
をプレス加工して反射鏡本体Ａを成形した際に
（第４図の状態）、その前面開口部Ｂ四周に外側方
方向に延設形成されたフランジ３を反射鏡本体Ａ
の前面開口部Ｂ前方向に曲げ起して形成される。
この時、反射面A2の左右口端A′2とフランジ３と
の間には巾Ｗが１〜３mm程度のスリツト穴４を形
成せしめ、そのスリツト穴４を中心にしてフラン
ジ３を反射鏡本体Ａの前面開口部Ｂ前方向に曲げ
起して左右フランジ２を形成するものである。 The upper and lower flanges 1 and the left and right flanges 2 are flanges that are formed to extend outwardly around the front opening B when a metal plate is pressed to form the reflector main body A (the state shown in Fig. 4). 3 to reflector body A
The front opening B is bent forward and formed.
At this time, a slit hole 4 with a width W of about 1 to 3 mm is formed between the left and right ends A' 2 of the reflecting surface A 2 and the flange 3, and the flange 3 is connected to the reflecting mirror with the slit hole 4 as the center. The left and right flanges 2 are formed by bending the front opening B of the main body A in the forward direction.
〈考案の効果〉
本考案自動車用ランプの反射鏡は斯様に構成し
たので、反射面の左右口縁から延設されたフラン
ジを反射鏡本体の前方開口部前方向に曲げ起して
左右フランジを形成する場合に、その応力が反射
面にほとんど影響せず、従つて反射面が変形する
恐れがなくなり、設計通りの配光性能に優れた反
射鏡となる。<Effect of the invention> Since the reflector of the automobile lamp of the present invention is constructed in this manner, the flanges extending from the left and right edges of the reflecting surface are bent forward toward the front opening of the reflector main body to form the left and right flanges. When forming a reflector, the stress has almost no effect on the reflective surface, so there is no fear that the reflective surface will be deformed, resulting in a reflective mirror with excellent light distribution performance as designed.
よつて、所期の目的を達成し得る。 Therefore, the intended purpose can be achieved.
