Headlamp device

摘要

To accelerate release of heat from within an internal space of a headlamp device and thereby to obviate fogging on a lens. The headlamp device (10) includes a headlight bulb (106) and position light bulbs (108). In addition, the headlamp device (10) has an intermediate member (130) between the lens (102) and a reflector (122) by which light from the headlight bulb (106) is reflected. The intermediate member (130) is provided with cutouts (144) through which a gas present on the lens (102) side relative to the intermediate member (130) can flow to the base member (100) side relative to the intermediate member (130). Thus convection of the gas takes place easily, whereby release of heat from within the internal space (114) is accelerated.
