Abstract:
An optical unit (10) is formed by securing the positions of a projection lens (11), a bracket (12), a light-source unit (13), and a first reflector (14) in relation to one another. When doing so, the projection lens is held at a predetermined position by means of the bracket (12), the light-source unit (13) is disposed behind the rear focal point of the projection lens (11), and the light emitted from the light-source unit (13) is reflected off the first reflector (14) toward the projection lens (11) in order to form a first light distribution pattern. A reflector unit (20) is provided with a second reflector (25) for reflecting forward the light emitted from the light-source unit (13) in order to form a second light distribution pattern. The optical unit (10) is attached to the front side of the reflector unit (20).
