Abstract
An optical unit includes a rotary reflector rotating in one direction around its rotation axis while reflecting light emitted from a light source. The rotary reflector is provided with a plurality of reflecting surfaces such that light of the light source reflected by the rotary reflector rotating is configured to form a desired light distribution pattern. Each of the reflecting surfaces includes a first reflecting surface configured to form a first partial region of the light distribution pattern, and a second reflecting surface configured to form a second partial region of the light distribution pattern different from the first partial region.
