の明るさが不均一となる。In the conventional vehicular lamp as described above, the light distribution performance in the front of the vehicle body is enhanced to improve the lighting effect, and the reflector has a uniform glossy feeling when the lamp is not lit. For the purpose of improving the appearance, the step 10 is provided on the parabolic effective reflection surface portion 7 to diffuse the light emitted from the bulb in the vehicle width direction, while the invalid reflection surface portion 8 not related to the light distribution of the lamp. No. 9 is the no-step surface, but if this is done, there is the problem that the lighting of the lamp does not look good. That is, when the lamp is viewed from the front of the vehicle body through the front lens (not shown) that hermetically covers the front opening of the lamp body 1 in the daytime, the effective reflection surface portion 7 looks like a vertical striped pattern because of step 10. However, this is interrupted at the boundary with the ineffective reflection surface portions 8 and 9 forming the no-step surface, so that the continuity of the pattern is lacking, and the reflected light from the ineffective reflection surface portions 8 and 9 is effective at the time of lighting. Since the light is stronger than the light diffused in step 10 of 7, the ineffective reflection surface portion is conspicuous and the overall brightness becomes nonuniform.

る。5 to 7 show a second embodiment of the present invention. FIG. 5 is a sectional view taken along line VV of FIG. 6, FIG. 6 is a front view of a lamp body, and FIG. 7 is a left side of the body. It is a side view. This embodiment shows an example applied to a lamp body 30 of a front turn signal lamp made of a single body. The lamp body 30 has a bulb mounting hole 31 formed at the center of the rear wall, and a front turn signal lamp bulb 32 is inserted from the rear through the bulb mounting hole 31. The right side surface of the lamp body 30 with respect to the bulb mounting hole 31 is curved with a large curvature so as to be convex toward the back side and extends obliquely forward to form an effective reflection surface portion 33, and the cylindrical step 34. Is formed over the entire surface. This step 34 is the lighting body 30
In a front view (as viewed from the direction of arrow C in FIG. 5), the stripe pattern is curved so as to be convex to the right in FIG. 6, and in the left side (as viewed in the direction of arrow D in FIG. 5), It is formed so as to exhibit a curved striped pattern (FIG. 7) to be convex. On the other hand, the inner surface of the body on the left side of the valve mounting hole 31 is formed as an ineffective reflection surface portion 35 by obliquely extending toward the rear of the vehicle body, and has a pseudo step 36 having substantially the same pitch as the step 34. Pseudo step 36
Has a wing shape in cross section, so that the invalid reflection surface portion 3
5 and a chamfered portion 3 formed of a convex curved surface connecting the linear portion 36a and the invalid reflection surface portion 35.
6b and has a striped pattern (FIG. 6) curved so as to be convex to the left when viewed from the front of the lamp body 30,
When viewed from the left side, it also has a striped pattern (FIG. 7) curved so as to be convex toward the left side. However, the effective reflection surface portion 33
In the vicinity of, the curve shows substantially the same as the striped pattern of step 34, and as it recedes from the effective reflection surface portion 33, it becomes closer to a straight line and approaches the striped pattern at the end portion of the reflection surface. Even with such a configuration, the same effect as that of the above embodiment can be obtained.

ップと考える。Here, the reason why the step 36 is chamfered into a convex curved surface with the wing shape is to prevent the stripe pattern from being doubled depending on the viewing angle (direction of arrow E in FIG. 5). . That is, if there are corners, the corners become stripes, so one step forms two stripes with the corners sandwiched between them. However, if the corners are chamfered parts 36b having a convex curved surface, the stripes are This is because it is not possible to form one striped pattern. Further, in the configuration in which the pseudo step 36 is located right beside the light source as shown in FIG. 3, when the step is formed in a sawtooth shape, the valley portion becomes a shadow and the shadow portion also becomes a thick striped pattern. I will end up. In addition, if the convex curved surface has a large radius of curvature, it is difficult to see the difference between steps, and it becomes difficult to see the striped pattern. In this respect, with the airfoil as described above, a beautiful striped pattern can be formed. In a V-shaped step whose cross-sectional shape is bilaterally symmetric, both the top and the valley have a striped pattern, and therefore two cylindrical steps are considered to be one step.

を有効反射面部の明るさと略等しくすることができる。As described above, in the vehicular lamp according to the present invention, the effective reflection surface portion is provided on the invalid reflection surface portion of the lamp body which has the effective reflection surface portion and the invalid reflection surface portion and is attached to the corner of the vehicle body. Since it is configured by providing pseudo steps with substantially the same pitch as the formed steps, when you look inside the lamp through the front lens from the front of the lamp, the entire inner surface of the lamp body has a continuous pattern, so the appearance of the lamp is improved. In addition, the brightness of the ineffective reflection surface portion at the time of lighting can be made substantially equal to the brightness of the effective reflection surface portion.
