To provide a headlight device for a vehicle of a novel structure capable of forming a plurality of kinds of light distribution patterns.
The headlight device for a vehicle 10 selectively forms a light distribution pattern among a plurality of them by selectively changing over light-shielding states of light irradiated from a bulb 30 and reflected by a reflector 32 with the use of a first shade 38 and a second shade 40. The first shade 38 and the second shade 40 can independently move toward a right-and-left direction as well as an up-and-down direction with a first movement mechanism 42 and a second movement mechanism 44, respectively, and shapes of the light distribution patterns to be formed are decided by changing combinations of the light-shielding states by the first shade 38 and the second shade 40.
