Abstract

Due to an effect of a solenoid of a moving mechanism, when a valve and a shutter are positioned at a first position, a light source is positioned at a first light source position and a shutter is in a state of closing a window. A lighting luminous flux from a light source is reflected by a reflector so as to be irradiated as a first light distribution pattern. Thus, a part of the lighting luminous flux is introduced to the reflector from the open window. Therefore, it is possible to effectively utilize the lighting luminous flux emitted from one valve in correspondence to a light distribution pattern.
