摘要： A vehicle headlight device 100 includes a light source 11, a Dove prism 40, and a rotation mechanism 50. The light source 11 emits light. The Dove prism 40 changes a propagation direction of light received at an incidence surface 401 to bring the light to a reflecting surface 402, and changes a propagation direction of light reflected at the reflecting surface 402 to output the light from an exit surface 403. The rotation mechanism 50 rotatably supports the Dove prism 40 about a line which passes through the incidence surface 401 and the exit surface 403 as an axis of rotation R, and rotates the Dove prism 40 in a direction opposite to a bank direction of a vehicle body in accordance with a bank angle k of the vehicle body.

摘要： A headlight unit (100) includes a light source (101), a light guide member (102), a projection lens (103), and a drive unit (112). The light source (101) emits a light beam for irradiating a forward area in a traveling direction. The light guide member (102) receives the light beam and emits planar light having a divergence angle. The projection lens (103) receives the planar light and projects it forward. The drive unit (112) changes a positional relationship between the light guide member (102) and the projection lens (103). The drive unit (112) is disposed in a region overlapping with the projection lens (103) in a direction perpendicular to an optical axis of the light guide member (102) from the light guide member (102), as optically viewed from an optical axis direction of the projection lens (103).
