A vehicle projection device comprising:
- a reflector that is provided in a vehicle and is provided with a reflective surface, with the reflective surface being a paraboloid of revolution and reflecting parallel light;
- an image member that is provided with an image and through which the light reflected by the reflective surface is transmitted;
- a lens through which the light that has been transmitted through the image member is transmitted, whereby the image is magnified and projected,
- a light source,
- a shield disposed between the light source and the reflective surface including a passage hole that is provided on a line between the light source and opposing edges of the reflector,
- the reflective surface ending before a vertex of the paraboloid, and the passage hole transmitting only light emitted from the light source to the reflective surface.
