Further, a decorative frame 7 which is close to the license plate lamp and surrounds the license plate housing portion 2 and surrounds the license plate housing portion 2 is provided, so that the license plate housing portion 2 has a good appearance. Reference numeral 8 is a stop lamp provided adjacent to the license plate lamp 4, a rear combination lamp integrated with a turn signal lamp, and reference numeral 9 is a rear bumper. Further, reference numeral 6b is a silver light-shielding coating applied to the back side of the front lens 6 so that light does not leak forward from the front lens 6.

[Problems to be solved by the invention]

Although the lamp chamber space of the lamp is sized so that the lamp body and the like are not deformed by the heat generated by the bulb 5,
It is desirable to make the lamp thinner or downsized for the space on the vehicle body side. However, in the above conventional technique,
Since the space in the vehicle width direction is taken away by the decorative frame 7, the size of the lamp in the vehicle width direction is limited, the lamp chamber space is reduced, and it is easily affected by heat. There was a problem that the socket part protrudes and the lamp becomes thick.

As described above, in the arrangement relationship between the lamp chamber space and the bulb in the above-described conventional lamp, the back side region of the decorative frame 7 (the region indicated by reference symbol S in FIG. 7) is not effectively used, and therefore the inventor has As a result of studying whether it is possible to make the lamp thinner and smaller by effectively using the region S, the present invention has been completed.

Therefore, the object of the present invention is to expand the lamp chamber space to the back side of other members such as a decorative frame, and by arranging the bulb obliquely, effectively utilize the lamp chamber space to achieve a thinner and smaller lamp. To do.

[Means for Solving the Problems]

In order to achieve the above object, in the vehicular lamp according to the present invention, a front lens is attached to a front opening of a lamp body in which a bulb is inserted, and another member such as a decorative frame is provided close to the front lens. In a vehicle lamp provided, a part of a front lens is recessed inward and extended to the back side of other members such as the decorative frame, and a lamp body and a front lens form a lamp chamber space having an L-shaped cross section. In addition, the bulbs are arranged so as to extend in the diagonal direction of the L-shaped lamp chamber space so that the bulb socket portion is located at a position corresponding to the depression of the front lens covered with another member such as a decorative frame. Is.

[Action]

Since the light room space is formed in an L shape, the light room space expands,
It is less susceptible to the heat generated by the valve. Further, since the bulb extends diagonally in the L-shaped lamp chamber space widened by the area behind the other member such as the decorative frame, the length occupied by the bulb in the thickness direction of the lamp becomes smaller by the amount of the inclination, that is, the lamp. The rear wall of the body can be formed close to the front lens, and the rearward projection amount of the bulb socket portion can be reduced.

It is supposed to be stopped. Reference numeral 19 denotes a shade member which is the front surface of the lamp chamber space B of the license lamp portion and is arranged on the back side of the front lens 16 with a predetermined distance d ₁ therebetween. The shade member 19 is formed in a bent shape following the recessed shape of the recessed portion 17 of the front lens 16 described later, and is formed in the engagement groove 14a formed inside the seal groove 14 and at the tip of the shade 13. The legs of the shade member 19 are engaged to close the front surface of the lamp chamber space B. The shade member 19 is made of a silver opaque resin in which reflective fine particles such as aluminum powder are dispersed and mixed, and the shade of the shade member 19 is the inner peripheral surface 12a ₁ of the lamp body portion 12a of the backup lamp. It is almost the same color as the silver color of the valve 18a
During the daytime (when the lamp is not lit), the entire design surface of the lamp 10 appears to be silver.

As shown in FIG. 7, a conventional lamp of this type is not provided with a member corresponding to the shade member 19 described above, and the area on the back side of the front lens 6 is painted silver and the bulb 5 is formed.
The above structure prevents the front light from going out from the front lens 6. Therefore, during the daytime (when the lamp is not lit),
External light is reflected by the silver coating surface 6b of the front lens 6,
Since it is possible to secure only the reflected light path corresponding to the plate thickness of the front lens 16, there is a problem that the lamp does not appear to have a depth and the appearance is not good. However, in this embodiment, the front lens

Further, a region corresponding to a region where the front lens is depressed 17 on the rear wall of the lamp body 12 is formed obliquely, and a bulb insertion hole 42 is formed in the slope region 40 (40a, 40b). And the lamp thickness direction (vertical direction in FIG. 1 and FIG. 2)
The valve insertion holes 42 inclined with respect to the valves 18a,
18b is inserted. That is, the valve socket portion (valve socket portion shown by the solid lines in FIGS. 1 and 2) of the valves 18a and 18b 18
The a ₁ and 18b ₁ are provided by the decorative frame 30 at a position that is completely invisible from the front of the lamp, and the light emitting portion of the bulb is located at the substantially central position of the L-shaped lamp chamber spaces A and B. Are arranged diagonally. That is, the lamp chamber spaces A and B are L-shaped in the horizontal plane due to the recessed portion 17 of the front lens, and the bulbs 18a and 18b extend in the diagonal direction of the L-shaped lamp chamber space.

As described above, in the present embodiment, the bulbs 18a and 18b are arranged obliquely with respect to the lamp front-rear direction, and the lengths of the lamp chamber spaces A and B in the lamp thickness direction are set as much as the bulbs 18a and 18b are inclined. The amount of protrusion of the bulb socket to the rear of the lamp is small. That is, as shown by the phantom line in FIG.
If b is arranged along the thickness direction of the lamp, the depth of the lamp is large, and the valve socket portions 18b ₁ and 18a ₁ project largely rearward as shown by the phantom lines in FIGS. 1 and 2. Therefore, the lamp cannot be made thinner and smaller. However, in this embodiment, the lamp body can be made thinner by the amount corresponding to the symbol h _{1 in} FIG. 2, and the rearward projecting amount of the valve socket portions 18b ₁ and 18a ₁ distributes the bulb parallel to the thickness direction of the wrap. Compared with the case of installation (shown by phantom lines in FIGS. 1 and 2), it is smaller by h ₂ and h ₃ . In addition, in the backup lamp section, the bulb socket section 18a ₁ is arranged obliquely with respect to the lamp thickness direction.
It is possible to increase the amount of light because not only the direct light from, but also the reflected light from the inner peripheral surface (reflection surface) 12a ₁ of the lamp body can be used.

Reference numeral 50 in FIG. 3 is an air passage provided on the back side of the lamp body 12, to which a U-shaped rubber tube 52 is attached to prevent dust and water droplets from entering the lamp body 12. I'm out. Further, reference numeral 60 in FIG. 1 denotes a cord bushing which is inserted through a power feeding cord 62 connected to the valves 18a and 18b and fitted into an opening formed in a vehicle body 64.
