VEHICLE HEADLAMP DEVICE

A vehicle headlamp device includes a headlamp unit, a light distribution direction changer, a traveling state changer, and an arithmetic controller. The headlamp unit is configured to illuminate an area ahead of a vehicle. The light distribution direction changer is configured to change a light distribution direction of the headlamp unit. The traveling state changer is configured to change a traveling state of the vehicle. The arithmetic controller is configured to, upon detecting a backward movement of the vehicle due to an operation received by the traveling state changer, cause the light distribution direction changer to change the light distribution direction of the headlamp unit more outward in a vehicle width direction of the vehicle than in a normal traveling state.
