[Prior Art] Conventionally, in vehicular lamps such as combination lamps, a rim made of metal such as iron, stainless steel, aluminum or the like or a hard resin is provided on the peripheral portion of the front lens. By covering the mounting portion with the vehicle body, the joint portion between the front lens and the lamp body, etc. so that they cannot be visually recognized from the outside, the external appearance of the lamp is improved. Therefore, this kind of rim surrounds the side of the front lens according to the shape of the lamp,
In addition, the thickness is thin and the cross-sectional shape is substantially U (or J) shaped, and one side edge of the side surface is in contact with the surface of the side surface of the front lens and the other side edge is in contact with the outer surface of the vehicle body. There is. FIG. 3 is a conventional example showing such a rim mounting structure, which will be briefly described. 1 is a lamp body, 2 is a front lens that covers a front opening 3 of the lamp body 1, and 4 is a periphery of the front lens 2. It is a rim that surrounds. A lens mounting portion 6 having an annular groove 5 that opens to the front is integrally provided in the front opening 3 of the lamp body 1, and the light from the lamp 8 is provided by protruding laterally at the peripheral edge of the rear surface. A rim mounting portion 7 that is substantially orthogonal to the axis L is provided. Front lens 2
A peripheral portion of the fixing portion 11 comprises an annular groove 9 provided on the front side and a mounting leg 10 provided on the back side, and the mounting leg 10 is inserted into the annular groove 5 of the lamp body 1. ,
And it is fixed by the adhesive 12.

The rim 4 is formed of a resin material in a cross-sectional shape as shown in the drawing, and thus has a stepped front surface portion 4A that forms substantially the same surface as the surface of the front lens 2, and an inner peripheral edge rear surface side of the front surface portion 4A. 4B projecting rearward on the
An outer wall portion 4C protruding rearward from the rear surface of the outer peripheral edge of 4A
And a cylindrical screw mounting portion 4D projectingly provided on the back surface of the front surface portion 4A so as to correspond to the rim mounting portion 7 of the lamp body 1, and the protrusion portion 4B is an annular shape of the front lens 2. Groove 9
, And is fixed by an adhesive 13. The outer wall portion 4C surrounds the periphery of the lamp body 1 so that the lamp body 1 cannot be visually recognized from the outside. Screw mounting part
The 4D has a screw hole 15 formed at its rear end face and is brought into close contact with the front surface of the rim mounting portion 7 of the lamp body 1, and is fixed to the rim mounting portion 7 by a set screw 14 screwed into the screw hole 15. There is.

[Problems to be Solved by the Invention] However, in such a conventional rim mounting structure, when the screw mounting portion 4D is brought into contact with the rim mounting portion 7,
Although the rim 4 can be positioned in the front-rear direction, the rim mounting portion 7 cannot be positioned accurately in both directions (directions orthogonal to the optical axis of the lamp). Therefore, when mounting the rim 4 on the lamp 8, Since it is necessary to temporarily fix it with a jig, there is a problem that the workability of assembling is poor. Further, since the rim mounting portion 7 needs to be provided so as to project in a direction orthogonal to the axis of the lamp body 1, a slide core is required, and the mold of the lamp body 1 becomes complicated. Furthermore, since the screw mounting portion 4D protrudingly provided on the back surface of the rim 4 constitutes a thick portion, sink marks are likely to occur in the portion of the front surface portion 4A corresponding to the screw mounting portion 4D during molding, and the appearance of the rim 4 There were various problems such as damage to

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and the purpose thereof is to have a relatively simple structure, which does not require temporary fixing of the rim at the time of assembly, and the lamp body. Another object of the present invention is to provide a rim mounting structure for a vehicular lamp in which the mold structure can be simplified and the problem of sink marks during molding of the rim can be eliminated and prevented.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention is provided with a lamp body, a front lens covering a front opening of the lamp body, and a surrounding of the front lens. In a vehicular lamp equipped with a rim, a rim mounting seat is integrally provided on a rear peripheral portion of the lamp body so as to project rearward, and a seat surface of the rim mounting seat is inclined at an appropriate angle with respect to the optical axis of the lamp. The rim is provided with a screw mounting portion, and the screw mounting portion is tilted with respect to the optical axis of the lamp at a substantially same angle as the rim mounting seat so that the screw mounting portion closely contacts the seat surface of the rim mounting seat, and a set screw is attached to the seat surface. It is intended to be fixed by.

[Operation] In the present invention, the rim mounting seat is integrally provided on the rear peripheral edge of the lamp body so as to project rearward, and the rear end surface, that is, the seat surface forms an inclined surface with respect to the optical axis of the lamp. Due to the close contact of the screw mounting portions, the front and rear of the rim and the positioning in the direction orthogonal to the optical axis of the lamp are simultaneously performed.

[Embodiment] Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings.

FIG. 1 is an enlarged sectional view of a portion A of FIG. 2 showing an embodiment of a rim mounting structure for a vehicle lamp according to the present invention, and FIG. 2 is a sectional view of the lamp. The same components and parts as those in FIG. 3 are designated by the same reference numerals and the description thereof will be omitted. This embodiment shows an example applied to a tail-and-stop lamp. A tail-and-stop 21 is arranged in a lamp chamber 20 formed in the center of the interior of the lamp body 1 via a bulb socket 22. .

The tail-and-stop valve 21 constitutes a double filament type valve, and is normally used as a tail lamp by energizing one filament, and is used as a stop lamp by energizing both filaments during braking.

The bulb socket 22 is fitted and fixed in a bulb insertion hole 23 formed in the center of the rear surface of the lamp body 1.

The front lens 2 that hermetically closes the front opening 3 of the lamp body 1 is colored red, and the inner lens 24 is arranged on the back side thereof. The inner lens 24 is white, and a saw-toothed light control unit 25 that refracts light emitted from the tail-and-stop valve 21 in a predetermined direction is formed in a central portion corresponding to the tail-and-stop valve 21.

A cylindrical rim mounting seat is provided around the rear edge of the lamp body 1.
26 is integrally projected rearward, and its tip surface, that is, the seat surface 27 is an inclined surface that intersects the lamp optical axis L of the combination lamp at an appropriate angle, and a screw hole 28 is formed in the center thereof. ing. The seat surface 27 is formed as an inclined surface facing the outer side of the vehicle body in a plan view, so that the vehicle body center side end a is located rearward of the vehicle body outer side end b.

The rim 4 surrounding the front lens 2 has a stepped front portion.
4A, a projecting portion 4B projecting rearward on the inner peripheral edge of the front surface portion 4A, and inserted and fixed in the annular groove 9 of the front lens 2, and projecting rearward integrally on the outer peripheral edge of the front surface portion 4A. 4C and a plate-shaped screw mounting portion 4E projecting obliquely rearward on the inner surface of the outer wall portion 4C corresponding to the rim mounting seat 26.
It consists of and. The plate thickness of the rim 4 is substantially the same throughout. The screw mounting portion 4E is inclined at the same inclination angle Θ as the seat surface 27 of the rim mounting seat 26, and a screw mounting hole 29 is formed corresponding to the screw hole 28.

When mounting the rim 4 having such a configuration, the rim 4 is inclined so that the rear end of the outer wall portion 4C is outside the front end as shown by the dashed line in FIG. 1 is inserted into the annular groove 9 from the front of the lamp, and then the rim 4 is rotated in the direction of the arrow in FIG. Place the set screw 14 in close contact with the seat surface 27 and screw the set screw 14 into the screw hole 28 from the screw mounting hole 29.
The 4E may be fixed to the seat surface 27.

Thus, according to such a rim mounting structure, the rim mounting seat
By making the screw mounting portion 4E closely contact the seat surface 27 of 26, the mounting angle of the rim 4 can be kept constant, and the rim 4 can be rotated to bring the screw mounting portion 4E into close contact with the seat surface 27. By doing so, since the seat surface 27 constitutes an inclined surface, the positioning of the rim 4 in the front-back direction and in the direction orthogonal to the lamp optical axis can be performed at the same time. Therefore, the rim 4 can be positioned without being temporarily fixed by the jig, and the workability of assembling the rim 4 is improved. Further, since the rim mounting seat 26 is provided so as to project rearward so as to be substantially parallel to the optical axis L of the lamp, the rim mounting seat 26 does not form an undercut portion and the mold structure of the lamp body 1 is simple. Can be converted. Furthermore, rim 4
Since the screw mounting portion 4E is substantially equal to the plate thickness of the outer wall portion 4C, sink marks due to shrinkage at the time of molding do not occur on the surface of the outer wall portion 4C, and the appearance of the rim 4 is not impaired.

Although the present embodiment has been described for the case of being applied to the rim of a tail-and-stop lamp, it goes without saying that the present invention is not limited to this and can be directly applied to a lamp such as a backward light.

[Effects of the Invention] As described above, in the rim mounting structure for a vehicular lamp according to the present invention, the rim mounting seat whose seat surface is inclined at an appropriate angle with respect to the optical axis of the lamp is provided at the rear peripheral portion of the lamp body. Toward the rim, the screw mounting portion is integrally projected toward the rim corresponding to the rim mounting seat, and the screw mounting portion is brought into close contact with the seat surface of the rim mounting seat and fixed by screwing. Since it is configured, by rotating the rim and bringing the screw mounting portion into close contact with the seat surface, the mounting angle of the rim, the front-rear direction, and the direction orthogonal to the lamp optical axis can be positioned at the same time. The workability of assembly can be improved without the need for temporary fixing of the rim. Further, since the rim mounting seat is provided so as to project toward the rear of the lamp body, it does not form an undercut portion, the mold can be manufactured easily, and the manufacturing cost can be reduced. Also, since the rim may be provided with a screw mounting part having a screw mounting hole through which a set screw is inserted, the plate thickness of the screw mounting part can be made approximately the same as that of the rim body. It is possible to prevent sink marks due to the difference in wall thickness, and it is possible to manufacture a rim with a good external appearance.
