光軸調整装置。 A vehicle body inclination detector provided at the front and rear of the vehicle body that detects and outputs a Gray code signal according to the inclination of the vehicle body, a Gray code-binary decoder circuit that converts the Gray code signal from the detector into a binary number, and the vehicle body. A subtracter that subtracts the decoded signal detected by the tilt detector, a binary-decimal decoder circuit that converts the output signal of the subtracter into a decimal number, and a motor that rotates the optical axis of the headlight. an optical axis drive device for changing the optical axis direction; an optical axis detection switch that sequentially switches a plurality of contacts in response to changes in the optical axis direction; and a position of the optical axis detection switch and the binary-decimal system. Depending on the output signal of the decoder, the motor drive circuit rotates the motor forward or reverse, and the output signal of the vehicle body tilt detector changes, and the motor drive circuit is controlled to be driven only when the output signal is in a stable state for a certain period of time. A headlight optical axis adjustment device consisting of an operation control circuit, a changeover switch that changes the optical axis adjustment from automatic to manual, and a selection switch that manually sets the optical axis of the headlight to a desired position. .
