Abstract

In a door mirror device for a vehicle, a projector protrudes out toward a lower side from a circuit board, and the projector projects a pattern onto a ground surface. Moreover, illuminating LEDs and guide bodies are fixed to a lower surface of the circuit board. Due to the illuminating LEDs generating lights and the guide bodies guiding these lights, the guide bodies irradiate the lights from lower ends, and the ground surface is illuminated. Here, the lower ends of the guide bodies are disposed further toward a lower side than the projector. Therefore, shadows, which are due to the projector, arising in lights that illuminate the ground surface can be suppressed.

Claims

1. A viewing device for a vehicle, comprising:

a viewing mechanism that assists viewing by a vehicle occupant of the vehicle;

an accommodating body in which the viewing mechanism is accommodated;

a projector that is provided at an interior of the accommodating body including a light emitter which emits light and that projects images provided at an image member by light which the light emitter has emitted, and an opaque, protruding member that protrudes out toward an outer side of the accommodating body and that envelopes the light emitter and includes a light-conducting opening at a distal end;

a second emitter that is provided at the interior of the accommodating body, that emits light, and that is different from the light emitter; and

a guide at which an exit portion is provided, and that guides light, which the second emitter has emitted, and that emits the light from the exit portion toward the outer side of the accommodating body, an entirety of the exit portion being disposed at the distal end of the protruding member or further toward the outer side of the accommodating body than the projector, in an emitting direction of light from the exit portion wherein the light emitter, the second emitter, and the projector are all attached to a same circuit board.

2. The viewing device for a vehicle of claim 1, wherein the guide is disposed at an outer side of a projection range of images from the projector.

3. The viewing device for a vehicle of claim 1, comprising a diffuser that diffuses light that is emitted from the exit portion.

4. The viewing device for a vehicle of claim 1, wherein the projector includes an exit portion that guides light that is separate from the exit portion of the guide.

5. The viewing device for a vehicle of claim 1, further comprising a third emitter that is provided at the interior of the accommodating body and that emits light,

wherein the second emitter and the third emitter are located on opposite sides of the light emitter.

6. The viewing device for a vehicle of claim 5, further comprising a second guide at which an exit portion is provided, and that guides light, which the third emitter has emitted, and that emits the light from the exit portion of the second guide toward the outer side of the accommodating body,

wherein the exit portion of the guide is disposed further toward the outer side of the accommodating body than the projector, in an emitting direction of light from the exit portion of the guide, and

the exit portion of the second guide is disposed further toward the outer side of the accommodating body than the projector, in an emitting direction of light from the exit portion of the second guide.

7. The viewing device for a vehicle of claim 1, further comprising a camera.
