  However, in such a mirror device with a lamp for a vehicle, the light source is provided in the vicinity of the light guide member so that the light guide member is uniformly illuminated. When the layout freedom in the housing is limited, it is difficult to uniformly illuminate the mirror device with a lamp for a vehicle.

  Therefore, the present invention has been made in view of the above problems, and is mounted on a mirror device with a lamp for a vehicle. For example, even if a light source and a light guide member are provided at positions separated from each other, An object of the present invention is to provide a vehicular lamp-equipped mirror device that emits light uniformly without deteriorating light distribution performance.

  In order to solve the above-described problems, the present invention provides a mirror housing having an opening having a rear-view mirror on the vehicle rear side and having a window on the outside of the vehicle, and illumination positioned at the window of the mirror housing. The illumination device is formed of a lens member and a lamp housing having a light source, and the lens member guides light from the light source in a predetermined direction, and transmits light from the light source. The transmission part is formed between the light source and the light incident part of the light guide part. At the front of the light source in the irradiation direction, at least a part of the light emitted from the light source is light of the light guide part. A light control member that controls to be directed toward the incident portion is provided.

In order to solve the above problems, the present invention is characterized in that the light control member is formed integrally with the lens member inside the window portion of the mirror housing.

  According to the present invention, even if the lens member of the lighting device is divided into the light guide part and the transmission part, and the light source is arranged at a position away from the light incident part of the light guide part, the emitted light from the light source is light. It is controlled by the control member and efficiently enters the light incident part of the light guide part.

That is, even if the light source is set inside the mirror housing and the light guide is separated so as to be located outside the mirror housing, the light from the light source is controlled by the light control member, and the mirror device with a lamp for a vehicle is used. The lighting device can be illuminated uniformly.

  According to the present invention, the light control member is formed on the inner side of the window portion of the mirror housing and integrally with the lens member, thereby improving the positional accuracy between the light guide portion of the lens member and the light control member. In addition, the light emitted from the light source can be controlled with higher accuracy. Further, by providing the light control member in the vicinity of the light source, it becomes easy to control the light, and further, the light source and the contents are not fully visible when viewed from the outside of the vehicle, and the appearance quality can be improved. .
