In an automatic leveling apparatus, a motor inclines an optical axis of a headlamp in an up and down direction relative to a vehicle body, a vehicle height sensor detects a change in a height direction of an axle portion of a front wheel or a rear wheel of a vehicle, and an involatile memory records a control constant inherent to the vehicle. CPU determines whether the control constant is recorded to the involatile memory, calculates a pitch angle based on the control constant inherent to the vehicle and a detecting output of the vehicle height sensor, and controls to drive the motor by generating a control signal for canceling the pitch angle. CPU calculates the pitch angle on a condition that the control constant is recorded to the involatile memory, outputs the control signal and stops to output the control signal to the motor otherwise. |
