As a concrete means for solving the above-mentioned conventional problems, the present invention provides a lens of a vehicular signal lamp in which a turn-in portion extending over a side surface of a vehicle body is provided, and a non-light-emitting portion is provided in the turn-in portion as necessary. In the structure, the lens is composed of an outer lens and an inner lens, the outer lens is formed by a single colored lens including the wraparound portion, the inner lens corresponds to substantially the entire surface of the outer lens, and A transparent portion formed of a transparent member having a lens cut directed toward the irradiation direction of the vehicular signal lamp, and a step is formed in a portion of the transparent portion of the inner lens corresponding to the non-light emitting portion. An attaching portion is provided which allows the opaque member to be attached to the outer lens side, and an opaque member having the same color as the outer lens is attached to the attaching portion if necessary. Serial to provide a lens structure of a vehicle signal lamp, characterized in that the non-light emitting portion is provided,
This is to solve the above-mentioned conventional problems.

【Example】

Next, the present invention will be described in detail with reference to an embodiment shown in the drawings. Reference numeral 1 in FIG. 1 denotes a lens of a vehicular signal lamp 10 according to the present invention. This lens 1 is an outer lens 2
The inner lens 3 is composed of a transparent portion 31 formed of a transparent member and an opaque portion 32 formed of an opaque member according to the present invention. There is. Here, the inner lens 3 will be described in more detail. The transparent portion 31 is formed of a transparent member, and
Is provided with a lens cut 31a such as a Fresnel cut for directing light from the vehicle as substantially parallel light in the irradiation direction of the vehicular signal lamp 10, and the provided range corresponds at least to the light emitting portion 21 of the outer lens 2. In this embodiment, the outer lens 2 is formed so as to correspond to the entire range of the outer lens 2, and a mounting portion such as a step is formed.
31b is provided so that the opaque portion 32 can be attached by an appropriate means. The opaque portion 32 is formed of an opaque member having the same color as the member on which the outer lens 2 is formed,
The area provided is a non-light emitting portion of the outer lens 2.
It corresponds to 22 and is configured to be attachable to the attaching portion 31b of the transparent portion 31 as necessary by means such as adhesion or fitting. Next, the operation and effect of the lens 1 having the above-described configuration will be described. For example, the related regulations regarding the destination of the vehicle in which the vehicle signal light 10 is mounted are the same as those in the conventional example. If the light emission is not recognized, the transparent portion 31 is shipped with the opaque portion 32 fixed to the mounting portion 31b. Since the non-light emitting portion 22 of the outer lens 2 is blocked by the opaque portion 32 of the inner lens 3 because the opaque portion 32 is fixed, the non-light emitting portion 22 of course does not emit light. In the conventional example, the light emitting portion 21 allows only the light directed toward the irradiation direction, that is, the rearward direction of the automobile to pass through as shown in FIG. 2 due to the lens cut 31a formed in the transparent portion 31 of the inner lens 3. Light emitting part 21 that occurred
From the above, the above-mentioned related laws and regulations are satisfied without generating the internal reflection light in the outer lens 2 reaching the non-light emitting portion 22.
