A vehicle headlamp is provided with: a frame; a lamp unit, which includes a first and a second connection sections and, which is rotatable with respect to the frame; a slider connected to first connection section and which is supported on the frame so as to be movable in a front-rear direction; a rotor connected to the second connection section and which is supported on the frame so as to be turnable in a horizontal direction; a drive operation section for moving the slider in the front-rear direction; and a rotation operation section for turning the rotor in the horizontal direction. The first connection section and the second connection section are positioned so as to be separated from each other substantially in the up-down direction.

There is provided a vehicle headlight. The vehicle headlight includes: a light source configured to emit light; a reflector reflecting the light; a projection lens projecting the light; a stationary shade blocking a part of the light emitted from the light source; a movable shade supported by the stationary shade as to move between a shielding position and a non-shielding position and configured to block a part of the light emitted from the light source; a drive mechanism including: a yoke; a coil disposed in the yoke; and an output shaft configured to move in an axial direction thereof in response to current supplied to the coil, and a transmission mechanism transmitting a driving force of the drive mechanism to the movable shade. At least a part of the yoke of the drive mechanism is formed in a single piece with the stationary shade.

A vehicular headlamp includes: a bracket having an actuator attaching portion that has a first fixation portion and a second fixation portion and part of which is a cuttable portion; a first actuator that is attached to the actuator attaching portion from one direction and is fixed via the first fixation portion; and a lamp unit that is supported by the bracket and that is capable of being tilted relative to the bracket by drive force of the first actuator. The actuator attaching portion is configured so that the cuttable portion can be cut off to detach the first actuator from the bracket in another direction than the one direction and a second actuator can be attached to the actuator attaching portion from the another direction and fixed to the actuator attaching portion via the second fixture portion.

A vehicle headlamp includes: a lamp outer casing; a lamp unit including: a light source unit having a light source that emits light, a reflector and a heat sink; a stationary frame; a movable frame that is supported by the stationary frame to be rotatable about a rotating shaft; a lens unit supported by the movable frame and having a projection lens; a first aiming operation shaft that adjusts an optical axis in the lateral direction; and a second aiming operation shaft that adjusts the optical axis in the vertical direction. A focal point of the light reflected by the reflector is coincident with a center of the rotating shaft. The lens unit is moved relative to the stationary frame 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.

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.

Provided is a vehicular headlamp that includes a light source unit, a reflector, a heat sink, a fixation frame fixed inside an external case of a lamp, a movable frame supported on the fixation frame to be movable in a vertical direction, a lens unit including a projection lens and a lens holder and supported on the movable frame to be movable in a horizontal direction, a first aiming operating shaft that performs optical axis adjustment, and a second aiming operating shaft that performs the optical axis adjustment. In particular, the lens unit moves in the horizontal direction and the vertical direction with respect to the fixation frame while a distance from a focus of light reflected by the reflector to the projection lens is constant, and the light source unit is fixed to the lamp housing while the heat sink is positioned outside the external case.
