An adjustment mechanism configured to adjust a reference position of an optical axis of a projection lens of a lens unit has a reference axis perpendicular to the optical axis and disposed in a plane which intersects with a focal point of the projection lens. The lens unit moves in an extension direction of the reference axis in accordance with rotation of a second screw. An acting point of a force to move the lens unit is disposed in a plane formed by the optical axis and the reference axis.
