To provide an optical axis direction control device of a head lamp capable of appropriately controlling an optical axis direction of the head lamp by controlling the optical axis direction of the head lamp by taking into consideration a turning radius during curve traveling of a two-wheel cycle.SOLUTION: An optical axis direction control device 1 of a head lamp is configured to: estimate a turning radius of an automatic two-wheel cycle during turning traveling on the basis of a bank angle detected by a bank angle sensor 5, and a steering angle detected by a steering angle sensor 6; and control an optical axis direction on the basis of a correction value obtained by correcting the estimated turning radius according to vehicle speed detected by a vehicle speed sensor 3, and a pitch angle detected by a pitch angle sensor 4.SELECTED DRAWING: Figure 1

    【課題】二輪車のカーブ走行時の旋回半径を考慮して前照灯の光軸方向を制御することにより、前照灯の光軸方向を適切に制御することができる前照灯の光軸方向制御装置を提供する。【解決手段】前照灯の光軸方向制御装置1は、バンクアングルセンサ5により検出するバンク角と、舵角センサ6により検出する舵角と、に基づいて自動二輪車の旋回走行時の旋回半径を推定すると共に、推定した旋回半径を車速センサ3により検出する車速に応じて補正した補正値と、ピッチアングルセンサ4により検出するピッチ角と、に基づいて光軸方向を制御する。【選択図】図1
