Patent ID: 7736038

Claim:
A vehicle headlight capable of obtaining a plurality of light distribution patterns, the vehicle headlight comprising: a light source that emits light; a reflector that reflects the light emitted by the light source; a projection lens that projects the light reflected by the reflector forward of a vehicle; a shade that forms the light traveling to the projection lens from the reflector into a plurality of light beams that form the light distribution patterns; a spring and a driving unit, configured to move the shade to a plurality of positions corresponding to the light beams, the driving unit including an attaching portion, and a first contact surface and a second contact surface that are substantially orthogonal to each other; a frame that includes a receiving portion to which the attaching portion is attached, a first contact receiving surface for positioning the driving unit in a first positioning direction and a second contact receiving surface for positioning the driving unit in a second positioning direction, the first positioning direction intersecting with an attaching direction in which the driving unit is attached to the frame by being in contact with the first contact surface, and the second positioning direction intersecting with the attaching direction and is substantially orthogonal to the first positioning direction being in contact with the second contact surface; and an attaching member for attaching the attaching portion to the receiving portion, wherein the spring includes a fixing portion that is fixed in the first positioning direction while being sandwiched between the driving unit and the frame, and a positioning portion that is positioned in the second positioning direction by being in contact with the driving unit.
