Abstract

PURPOSE:To eliminate the power consumption except in adjusting the optical axis of illumination by fixing the optical axis of illumination through the control of conduction in an operating apparatus by a switch mechanism which links with an operation mechanism and making the simple operation apparatus which generates reversible mechanical displacement. CONSTITUTION:The operating apparatus (electrical servo-motor 3) which generates the dispalacement for varying the optical axis of a front illuminating lamp 1 is reversibly operated by switching the conduction signal. Further, the conduction signal for the servo-motor 3 is obtained by the switching mechanism 7 consisting of a plurality of contacts linked with the operating mechanism (revolving screw 3a and movable rack 3b equipped with nut) which transmits the displacement of the servo-motor 3 to the front illuminating lamp 1, and a switch 6 which selects a plurality of contacts, and thus the position capable of varying the optical axis of the front illuminating lamp 1 is determined by the switching mechanism 7. Accordingly, the optical axis is not altered by the change with a passage of time.
