The present invention is a vehicle light that is installed as a built-in type at the tip of a rear spoiler.The lens portion is shaped to serve as both the upper and lower surfaces of the tip of the spoiler, and the surface in contact with the rear spoiler is a curved or inclined surface. The spoiler is characterized in that a spring is interposed between the spoiler and the support section inside the spoiler to maintain the normal shape with a required tensile force.
以下、本考案を図面に示す実施例に基づいて詳
細に説明する。
Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

と曲面の中心点の距離（第４図参照）である。 1 to 4 show an embodiment of the present invention, in which a lamp body 1 is shaped to also serve as the tip of a spoiler 10, and the contact surface between the body 1 and the spoiler 10 is a curved surface with a radius R. A spring 2 is interposed between the back surface of the main body 1 and the support part on the side of the spoiler 10, and its force brings the lamp main body 1 into close contact with the spoiler 10, and maintains a predetermined form against the external force of the allowable load. That's what I do. The tensile force T of the spring 2 for this purpose is T≦l 1 ·W/μ. However, W is the maximum allowable load, μ is the friction coefficient of the contact surface between the lamp body and the spoiler, and l 1 is the distance between the load point and the center point of the curved surface (see Figure 4).
また、前記ランプ本体１の背面の数個所に位置
決め用の突起３を形成し、スポイラー１０側の凹

接触面に移動が生じてランプ本体１が傾く。これ
により、ランプ本体１の破損が防止される。 With this structure, when a force exceeding the allowable load is applied to the lamp body 1 from above or below,
The lamp body 1 is tilted due to movement of the contact surface. This prevents damage to the lamp body 1.
外力が消失すると、バネ２の力により元に戻
る。この時、位置決め用突起３が再び凹部と嵌合
し、正規の形態となる。 When the external force disappears, it returns to its original state due to the force of spring 2. At this time, the positioning protrusion 3 fits into the recess again and assumes its normal shape.
また、本体１の特にレンズの部分がスポイラー
先端部の上下両面を兼ねる形状となつているた

くなり、所望の配光が得られる。 Furthermore, since the lens portion of the main body 1 is shaped to serve as both the upper and lower surfaces of the spoiler tip, it becomes easier to emit light upward from the light source (such as an LED) 4, and a desired light distribution can be obtained.

A spring 2 is interposed between the central part of the back of the main body and the support part on the spoiler side.

It rotates or slides using the outer edge of the contact surface with 0 as a fulcrum, and concentration of load on one point is prevented. This prevents damage to the lamp.

As described above, according to the present invention, the contact surface with the spoiler is used as a guide for rotation or sliding, and is tensioned by a spring to maintain a predetermined shape. Therefore, when an excessive load is applied, the rotation or sliding prevents load concentration. It is effective in preventing damage. In addition, the tip of the spoiler has a shape that serves as both the top and bottom, making it easier to emit light upwards.
Desired light distribution can be easily obtained. Furthermore, since the shape is maintained using the force of the spring, assembly work becomes easier.
