The function of notifying the surroundings of the situation cannot be performed sufficiently. Further, when the indicator lamp is provided on the end face on the front side of the sliding door or the swing door of the vehicle door structure, the indicator lamp cannot be confirmed from the rear of the vehicle unless the swing door is opened 90 degrees or more. In this regard, in the configuration described in Patent Document 3, since light is emitted from the outer surface (side surface) of the door, it is confirmed from the rear of the vehicle that light is emitted without opening the swing door by 90 degrees or more. Can do. However, since the lamp housing is provided across the inner surface and the outer surface of the door of the vehicle, it is necessary to ensure waterproofness in the portion on the outer surface side. Then, there are problems that the structure becomes complicated and the number of parts increases.

  An object of this invention is to provide the light-emitting device which can aim at the simplification of a structure.

  A light emitting device according to the present invention slides open and closes a partial region of a door opening provided on a side portion of a vehicle body, and defines a window frame defining the opening, and an outer side and an inner side in the opening of the window frame. A sliding door provided with a window portion having a translucent member and a translucent member, and a pivotable attachment to the vehicle body via a pivotal support mechanism, at least when the sliding door is fully open And a swing door that opens and closes another partial region of the door opening together with the sliding door when fully opened, and is a light emitting device provided in a vehicle, wherein the inner surface of the translucent member in the window And a light emitting portion that emits light when at least the swing door is open.

  In this light-emitting device, the light-emitting portion is disposed on the inner side of the inner surface of the translucent member in the window portion. Thereby, the light-emitting device can ensure waterproofness without requiring waterproof parts or the like. Therefore, in the light emitting device, the configuration can be simplified. The light emitting unit emits light at least when the swing door is open. The light emitted from the light emitting part is transmitted through the translucent member and directed to the outside of the slide door that opens and closes another partial region together with the slide door. Thereby, the light-emitting device can notify the rear side of the vehicle, for example, that the swing door is open.

Thereby, when the swing door is opened, the light emitting portion is positioned on the end portion (tip portion) side of the swing door away from the rotation support mechanism. Therefore, the position of the end portion of the slide door when the swing door is opened can be informed to the surroundings.

  In one embodiment, the translucent member has a lower transparency on the edge side than the other part, and the light emitting part may be arranged inside the part with a low transparency. Thus, by arranging the light emitting part at a position where the transparency of the edge of the translucent member is lower than that of the other part by the smoke film or the like, the light emitting part is hardly visible from the outside of the translucent member. Therefore, the designability can be improved. In addition, low transparency shows that the transmittance | permeability of visible light is ensured 70% or more, for example. Therefore, the light emission by the light emitting unit can be recognized from the outside of the translucent member, and the notification function by the light emission of the light emitting unit can be maintained.

  In one embodiment, the light emitting unit may be covered with a covering member so as not to be seen from the inside of the vehicle. Thereby, the design property in a vehicle can be improved.

  In one embodiment, a detection unit that detects the open state of the slide door may be provided, and the light emitting unit may emit light when the detection unit detects the open state of the slide door. Thereby, in addition to the swing door being open, it is possible to notify the surroundings of the vehicle that the slide door is open or the slide door is closed.

As shown in FIG. 4, the light emitting device 30 includes a light emitting unit 32, an open detection unit 34, and a power supply unit 36.

  The light emitting unit 32 emits light. The light emitting unit 32 is, for example, an LED (light Emitting Diode). As shown in FIG. 5, the light emitting portion 32 is disposed inside the window portion 20 on the inner side than the inner surface 20 s of the glass 20 b. Specifically, a plurality (six in FIG. 3) of light emitting units 32 are arranged at predetermined intervals in the vertical direction at the edge E on the front side of the window 20. Although the luminescent color of the light emission part 32 is not specifically limited, For example, it is red.

  The arrangement of the light emitting unit 32 will be described in more detail. Initially, the structure of the slide door 6 in which the light emission part 32 is arrange | positioned is demonstrated. As shown in FIG. 5, the window frame 20 a is formed by an outer wall (outer plate) 6 a of the slide door 6. The outer wall 6a is fixed to a door frame 40 arranged in a frame shape along the periphery of the opening S. The glass 20b is fixed to the window frame 20a with an adhesive 41.

  The light emitting portion 32 is fixed to the side portion 40a of the door frame 40 located on the front side of the opening S, and is constituted by an outer wall 6a protruding rearward from the side portion 40a and a garnish (covering member) 43 that is a lining. Located in the defined space. The light emitting part 32 is covered with a garnish 43 so as not to be seen from the inside (vehicle inside) of the vehicle body 2. The tip of the light emitting part 32 protrudes from the end S1 of the outer wall 6a when viewed from the glass 20b side (outside). That is, when viewed from the glass 20b side, the tip portion of the light emitting portion 32 is exposed.

  In the present embodiment, the edge 20e of the glass 20b has an irradiation light transmission part 20f that transmits the light emitted from the light emitting part 32, and a non-transmission part 20g in a part other than the irradiation light transmission part 20f of the edge 20e. , Is provided. The opaque portion 20g is formed by printing a black ceramic having a transmittance of 0%. The irradiation light transmitting portion 20 f is a smoke film disposed in a portion corresponding to the light emitting portion 32. The irradiated light transmitting portion 20f has lower transparency than a portion other than the edge 20e of the glass 20b (for example, the central portion of the glass 20b). Here, the low transparency means that a visible light transmittance of 70% or more is secured, for example. The edge part 20e is the edge E side of the window part 20, and is, for example, a part from the front end part of the glass 20b to the vicinity of the fixed position of the garnish 43 (part indicated by an arrow in FIG. 4). With such a configuration, when the edge portion 20e is viewed from the outside of the glass 20b, the adhesive 41 positioned inside the non-transmissive portion 20g, the end portion S1 of the outer wall 6a, and the like cannot be visually recognized. Further, the visibility in a state where the light emitting unit 32 located inside the irradiation light transmitting unit 20f is not emitting light is lowered, and the light emitting unit 32 becomes visible in a state where the light emitting unit 32 emits light.
