A vehicle lighting device includes: a lamp unit (1) for concentrating light; a lamp unit (101) for diffusion; a lamp housing (25) and a lamp lens (26), partitioning a lamp room (27); and an optical-axis adjuster (28) which is integrally mounted in the lamp housing (25) in an optical-axis adjustable manner in a state in which the lamp unit (1) for concentrating light and a lamp unit (101) for diffusion are integrally disposed in the lamp room (27). The lamp unit (1) for concentrating light radiates a light distribution pattern (SP) for concentrating light. The lamp unit (101) for diffusion radiates a light distribution pattern (WP) for diffusion. As a result, in this vehicle lighting device, one lamp unit (1) for concentrating light is provided which satisfies a main light distribution standard and forms a light distribution pattern (SP) for concentrating light as a standard for optical axis, thereby facilitating adjustment of light distribution and allowing for precise adjustment of light distribution. |
