  Although not shown, a reflection structure (for example, a prism structure) is formed in the longitudinal direction on the outer surface of the light guide member 20 on the inner panel 10 side, and light guided in the light guide member 20 is guided. While being guided in the longitudinal direction in the optical member 20, the light reflected by the reflecting structure and exceeding the critical angle is sequentially emitted from the side surface of the light guide member 20, and the light emitted from the side surface is the vehicle. Light emitted from the lamp.

  In addition, the light guide member 20 is bent toward the inner panel 10 on the rear side of the vehicle, and in FIG. 2, the light guide member 20 is not seen hidden behind the inner panel 10, but one end portion 21 (not shown) of the light guide member 20 is The inner panel 10 is disposed on the back surface side of the inner panel 10 or through a through opening provided in the inner panel 10.

A light source (not shown) is arranged in the vicinity of one end 21 (not shown) of the light guide member 20 so as to face the one end 21, and light from this light source Enters the light guide member 20 from the end 21 on one side.
In addition, as a light source for making light inject into the edge part of the one side of the light guide member 20, self-light-emitting semiconductor type light sources, such as LED and EL (organic EL), can be used suitably.

  On the other hand, on the vehicle front side of the light guide member arrangement portion 16 of the inner panel 10, a storage portion 17 is provided to receive the other end portion 22 that is the end portion of the light guide member 20 on the vehicle front side. Yes.

FIG. 3 is an enlarged perspective view around the storage portion 17.
As shown in FIG. 3, an opening 18 for irradiating light (see arrow) emitted from the other end 22 of the light guide member 20 to the front side of the vehicle is formed in the storage portion 17. The light emitted from the end 22 on the other side through the opening 18 is favorably irradiated in the viewing angle direction on the front side of the vehicle.

Next, the effect of 1st Embodiment demonstrated above is demonstrated.
As shown in FIG. 2, the light guide member 20 is disposed such that the side surface of the light guide member 20 is inclined (slant) obliquely outward from the vehicle front side toward the rear side.

And the light which entered into the light guide member 20 from the edge part 21 (not shown) of the one end side which is an edge part by the side of the vehicle rear side of the light guide member 20 is sequentially guided through the light guide member 20. Light is emitted from the side surface and light is emitted in the light irradiation direction of the clearance lamp by the emitted light.
On the other hand, the light guided to the other end 22 which is the end of the light guide member 20 on the front side of the vehicle is emitted from the other end 22.

  The other end 22 of the light guide member 20 is accommodated in the accommodating portion 17 of the inner panel 10, and the light emitted from the other end 22 usually does not go out of the accommodating portion 17, so it is useless. In this embodiment, an opening 18 through which light can be emitted in the viewing angle direction on the front side of the vehicle is provided in the present embodiment.

As a result, the light emitted from the end 22 on the other side is irradiated in the viewing angle direction on the front side of the vehicle, and is effectively used to enhance the visibility in the viewing angle direction on the front side of the vehicle.
Therefore, even when the side surface of the light guide member is arranged so as to face the side of the vehicle, it is possible to irradiate light in the viewing angle direction on the front side of the vehicle and improve the light use efficiency. A lamp can be realized.

In the first embodiment, the case where the storage portion 17 is formed on the inner panel 10 has been described as an example. However, the storage portion 17 is not necessarily formed on the inner panel 10.
For example, a part in which the storage portion 17 having the opening 18 is integrally formed with the reflector 15 (hereinafter also referred to as a reflector part) is prepared, and the reflector part is attached to the inner panel 10. Good.

  By the way, in the case of 1st Embodiment, when there exists light radiate | emitted largely from the edge part 22 of the other side of the light guide member 20 in a vehicle inner side direction, it will be provided in the vehicle front side of the accommodating part 17 shown in FIG. There is a possibility that the turn lamp 30 (see FIG. 4) arranged in the reflector 15 is lit in a pseudo manner or the light emitting area becomes unclear.

More specifically, it will be described with reference to FIG.
In FIG. 4, among the light emitted from the end 22 on the other side of the light guide member 20, the light emitted largely in the vehicle inner direction is indicated by an arrow.

Such emitted light may cause the turn lamp 30 to emit light, which may create a pseudo-lighted state that looks as if the turn lamp 30 is lit even though the turn lamp 30 is not lit.
Conversely, even if the turn lamp 30 does not emit light enough to be recognized as pseudo-lighting, the light guide member 20 may be recognized as if it is lit in the amber color of the turn lamp 30.

Further, when the emitted light greatly emitted toward the inside of the vehicle as shown by an arrow in FIG. 4 is reflected by the reflector 15 and irradiated to the front side of the vehicle, the area of the reflector 15 is recognized as emitting light. The
If it does so, since it will be in the state where the light emission area of the light guide member 20 is extended to the area of the reflector 15, it will become unclear to what extent the light emission area of the original light guide member 20 is.

  Hereinafter, as a second embodiment, a vehicular lamp that further improves the above problem will be described.

(Second Embodiment)
FIG. 5 is an enlarged perspective view of the vicinity of the storage portion 17 as in FIG. 3.
As shown in FIG. 5, in the second embodiment, a lattice extending in the vehicle vertical direction is provided in the opening 18 of the storage portion 17 of the inner panel 10, and a plurality of slits 19 along the vehicle vertical direction are formed in the vehicle width direction. Yes.
As a configuration for providing the slit 19 in the opening 18, a lattice structure may be directly formed at the opening 18, or another part in which the slit 19 is formed in the lattice structure is prepared. This separate part may be fixed to the opening 18.

FIG. 6 is a cross-sectional view showing a cross section in the vicinity of the storage portion 17 of the second embodiment, similarly to FIG.
As shown in FIG. 6, out of the emitted light emitted from the end 22 on the other side of the light guide member 20, the emitted light having high straightness along the direction of the slit 19 passes through the slit 19 and forwards the vehicle. Irradiated in the side viewing angle direction.

On the other hand, the emitted light emitted with a large angle toward the inside of the vehicle as indicated by an arrow in FIG. 4 hits the lattice forming the slit 19 and cannot pass through the slit 19.
That is, the outgoing light emitted with a large angle inside the vehicle as shown by the arrow in FIG. 4 is shielded by the grating.

As described above, the light control unit including the slit 19 is provided in the opening 18 of the storage unit 17 of the inner panel 10, and the direction of the light emitted from the end 22 on the other side of the light guide member 20 is controlled. While realizing the irradiation of light in the viewing angle direction on the front side, there is no fear that the turn lamp 30 as described with reference to FIG. 4 will be quasi-lit, and the area of the reflector 15 emits light. Thus, the vehicular lamp can be obtained in which the light emitting area of the original light guide member 20 does not become unclear.
Therefore, according to the aspect of 2nd Embodiment, even if the lamp (the turn lamp 30 which has the reflector 15 in this example) is arrange | positioned near the edge part used as the light emission end of a light guide member, a favorable vehicle lamp Can be provided.

  In the above description, the lamp of the turn lamp 30 having the reflector 15 has been described as an example. However, the types of lamps arranged in the vicinity of the end portion serving as the light emitting end of the light guide member are particularly limited. Instead, when a lamp that may cause the problem described above is arranged in the vicinity of the end serving as the light emitting end of the light guide member, as in the second embodiment, the light guide The same effect can be obtained by providing the light control unit on the vehicle front side of the end portion which is the light emitting end of the member.

  Further, when the slit 19 is formed by providing a lattice in the opening 18 of the storage portion 17 of the inner panel 10 as in the second embodiment, the slit 19 is adjusted by adjusting the opening direction of the slit 19. Since the irradiation direction of the light emitted from the light guide member 20 can be finely adjusted, even if the direction of the emitted light emitted from the other end 22 of the light guide member 20 does not completely match the direction in which the light is desired to be emitted, It can adjust so that light may be irradiated to the direction which wants to irradiate light.

  In the above description, the slit 19 is formed by providing a grid extending in the vehicle vertical direction in the opening 18 of the storage portion 17 of the inner panel 10. However, the method of forming the slit 19 is to provide a grid extending in the vehicle vertical direction. It is not limited to.

As shown in FIG. 7, an inner lens 40 is provided in the opening 18 of the housing portion 17 of the inner panel 10, and the inner lens 40 is painted so as to form slit-like transmission windows on the upper and lower sides of the vehicle. The effect of can be obtained.
In this case, it is preferable to provide a step for the mask on the inner lens 40.

  Further, when the inner lens 40 is provided in the opening 18, as described above, the slit-shaped transmission window is not limited to being formed by painting. For example, the light incident surface (light guide member) of the inner lens 40 is used. A prism structure that controls (polarizes) the light emission direction may be formed on the light emission surface or the light emission surface.

  In the above description, the emitted light emitted from the end portion 22 on the other end side of the light guide member 20 has been described as a problem of being incident on the reflector 15 and the turn lamp 30. However, the aspect of the second embodiment is such It is not only valid if.

In recent years, the vehicular lamp has a shape that is inclined (slant) from the front side of the vehicle toward the rear side of the vehicle. In such a vehicular lamp, an inner panel is formed on the inner side of the vehicle near the end of the light guide member. In this case, if light is emitted largely from the end of the light guide member to the inside of the vehicle, the emitted light may be reflected by the wall surface of the inner panel and become glare light. is there.
Even in such a case, as described above, the light control unit is provided, and the light that is largely emitted from the other end 22 of the light guide member 20 to the inside of the vehicle is shielded or polarized to guide the light. The generation of glare light can be suppressed by preventing the light emitted from the end 22 of the member 20 from being reflected by the wall surface of the inner panel.

  As described above, the present invention has been described based on the specific embodiments. However, the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention. It is included in the present invention.
