2. Description of the Related Art FIG. 2 is a sectional view of a main part of a vehicular lamp equipped with a conventional protector. A seal groove 1a is formed along the periphery of the front opening of the lamp housing 1. On the other hand, the front lens 2 is integrally provided with a ridge-shaped lens leg 2a protruding rearward.
a is inserted in the seal groove 1a. A thermosoftening adhesive hot melt 3 is injected into the seal groove 1a to fix the lens leg 2a in an airtight manner. Illustrated 2
Reference numeral b is a prism formed on the rear surface of the front lens.

In the present invention, the names of front and rear are, respectively, that the direction of projection of the lamp is the front and the opposite direction is the rear. It does not necessarily coincide with the traveling direction of the vehicle equipped with this lamp. In the accompanying drawings, the left side is the front and the right side is the rear. The front lens 2 of the vehicular lamp according to this conventional example has its lens leg 2
A flange-shaped portion 2c is provided around a. The vehicular lamp configured as described above is fitted into an opening provided in the exterior plate 4 of the vehicle body, and its peripheral portion is overlapped and mounted. Since the fitting portion and the overlapping portion do not always fit perfectly due to the manufacturing error and the mounting error of the constituent members, a clearance of several millimeters is generally provided and the protector 5 is interposed.

The protector 5 of this embodiment has a substantially U-shaped cross section formed by a plane perpendicular to its peripheral edge, and the flange 2c of the lens is sandwiched in the front-rear direction by the two parallel sides of the U-shape. I am wearing it. The protector 5 is generally made of a flexible synthetic resin material, but is pre-bonded to the lens flange 2c so as to facilitate the work of assembling the protector 5 to the vehicle body exterior plate. This is because if the lens and the protector are integrally bonded to each other in this way to form an integrated assembly component, the operation of fitting into the opening provided in the vehicle body exterior plate 4 is easy.

[0005]

The protector of the conventional example shown in FIG. Problems with bonding work,
B. The freedom of choice of protector material,
C. The problem that the appearance of the lens flange part is not good,
There is. If the protector 5 is molded and then adhered to the lens flange 2c, a great deal of labor is required and a time loss is required to wait for the adhesive to cure.
Reduce work efficiency. In addition, depending on the type of adhesive, harmful solvent vapor may be emitted, which requires a large management cost for maintaining the working environment, and special consideration should be given to worker rest and regular health checkups. I need. Furthermore, since the adhering work requires a cleaning operation of the adhering surface as a pretreatment, the material cost and labor cost are further increased. To eliminate these problems,
It is also possible to integrally form the protector 5 using a synthetic resin material having a weldability to the constituent material of the front lens 2. In this case, known techniques such as the insert molding method and the two-color molding method can be used. However, if the material of the protector is selected under the condition that it must have a weldability with respect to the front lens, the degree of freedom in selection is narrowed. When the freedom of choice is restricted, some disadvantages have to be put up. For example, if the front lens is acrylic resin or polycarbonate, Mitsui Du
Alkrin 2060BK manufactured by Pon Chemical Co., Ltd. can be used, but if the condition is that it has weldability to the front lens, the above-mentioned Alklin 6020B can be used.
K cannot be used. If you look for a similar product that has weldability to the front lens (acrylic or polycarbonate), you can find, for example , Tuftec S29 manufactured by Asahi Kasei Corporation.
Although there is 52, it is necessary to accept some disadvantages such as lack of gloss in appearance. Furthermore, when the vicinity of the protector 5 of the conventional example of FIG. 2 is viewed from the direction of arrow E, the edges of the protector 5 and the edges of the vehicle body exterior plate 4 are visible and the appearance is not good, so the coating film 6 is provided. . This invention has been made in view of the above circumstances, without the need for bonding operation during assembly work, moreover, possible to constitute the protector with a material that <br/> have a weldability with respect to the lens material And the appearance around the lens flange can be improved.
An object of the present invention is to provide a protector for a vehicular lamp having a lens flange portion.

[0006]

In order to achieve the above object, the present invention provides a protector made of a flexible synthetic resin interposed between a flange-shaped portion of a front lens of a vehicle lamp and a vehicle body exterior member. in the above protector is formed integrally with said front lens by synthetic resin material that having a heat seal against the front lens, and, "the front lens
Outside the body and the flange-shaped part provided on the outer peripheral side of the lens leg of
At least a part of the overlapping portion with the mounting member, and
It covers the outer peripheral surface of the flange-shaped part and
"L-shaped part of the same tone" and "from the inner peripheral surface of the L-shaped part"
White or reaching the base of the lens leg toward the inside of the lamp
And an extension portion of a color tone different from that of the vehicle body exterior member " .

[0007]

The protector for a vehicular lamp having the above-mentioned structure does not require an adhering operation for its assembling, so that the work is easy and there is no risk of a work environment related to the adhering. Since the protector covers the rear surface of the lens flange portion, the edge of the vehicle body exterior plate and the like do not appear in the appearance when this area is viewed from the front, so that the appearance is not impaired. In the above configuration, the material of the protector is required to have a good heat-welding property with respect to the front lens, so that the material selection of the protector is restricted. However, since the protector of the portion that covers the rear surface of the lens flange in the above-mentioned configuration is visible from the front through the lens flange, even if the protector material has no gloss, the surface reflection of the lens flange causes glossiness. Given a feeling
It Moreover, of the parts that appear in the exterior of the vehicle lamp,
The part where the lens flange overlaps the body exterior member
Has the same color tone as the body color through the transparent lens flange.
You can see, and the part inside is a transparent lens flange
The appearance is good because it looks transparent and has a color tone different from that of the car body .
