A lamp device for vehicles includes a lamp unit for irradiating light in a desired light distribution pattern, a support body configured to support the lamp unit so as to be tiltable up and down, and tiltable right and left, and an actuator for tilting the lamp unit up and down with respect to the support body, and for tilting the lamp unit right and left with respect to the support body. The actuator includes a right-and-left tilting mechanism and an up-and-down tilting mechanism provided in an actuator housing. The right-and-left tilting mechanism includes an output shaft capable of turning in a right-and-left direction coupled to said lamp unit. The up-and-down tilting mechanism includes an output portion capable of moving said actuator housing back and forth with respect to the support body.

1. Field of the Invention
This invention relates to a novel lamp device for vehicles. More specifically, the invention relates to an art for arbitrarily changing the direction of irradiation up and down, and right and left.
FIG. 1 illustrates an embodiment of when a lamp device for vehicles of the invention is applied to a headlight for an automobile, and is a vertical sectional view schematically showing the whole device.
FIG. 2 is a disassembled perspective view showing a lamp unit and a two-function actuator separated away from a bracket.
FIG. 3 is a bottom view of a coupling boss possessed by the lamp unit.
Described below with reference to the drawings are exemplary embodiments of the lamp device for vehicles of the present invention. The illustrated embodiments are examples of when the invention is applied to a headlight for an automobile.
First, the outline of the headlight for the automobile will be described with reference to FIG. 1.
A headlight 10 for the automobile comprises a lamp unit 30 that is arranged in a housing 20 having a lamp chamber 21 which is a nearly sealed space, the lamp unit 30 being allowed to turn up and down, and right and left. In the housing 20, an opening is covered with a transparent cover 23 in the front surface of a lamp body 22 of the shape of a container having an opening in the front.
