PURPOSE:To facilitate the levelling operation of a head lamp by driving a motor, changing the angle of optical axis for the head lamp, and setting up the motor automatic stop switch which is switched in response to this movement. CONSTITUTION:The motor 3 is connected to the head lamp 6 through the worm gear 4 and the worm wheel 5 and the motor automatic stop switch 9 is set up at the worm wheel 5. When the changeover switch 15 operates and the motor 3 revolves, this revolution is transmitted to the head lamp 6 through the worm gear 4 and the worm wheel 5 and changes the optical axis of the head lamp 6. On the other hand, the revolution of the worm wheel 5 moves the motor automatic stop switch 9. When this switch 9 reaches the preset value, the motor 3 stops. As described above, only by switching the changeover switch at hand, the optical axis of the head lamp 6 can be changed and its operation is facilitated. |
