Abstract
A vehicle headlamp includes: a lamp outer casing; a lamp unit; a stationary frame; a movable frame that is supported by the stationary frame to be rotatable about a first rotating shaft extending in a lateral direction or a second rotating shaft extending in a vertical direction; a lens unit disposed in the lamp outer casing and supported by the movable frame; a first aiming operation shaft that adjusts an optical axis, and a second aiming operation shaft that adjusts the optical axis. A focal point of the light reflected by a reflector is coincident with a center of the first or second rotating shaft. The lens unit is rotated about the first or second rotating shaft such that a distance between the focal point and the projection lens is constant. The heat sink is positioned on the outside of the lamp outer casing.
