To provide a headlight leveling device of a motor vehicle which allows expansion/contraction adjustment of an adjusting rod to be manually adjusted as well as by a motor drive structure and achieves high stability.SOLUTION: A headlight leveling device of a motor vehicle includes a housing 5. A motor assembly 2, a composite gear 4, a sprocket 6, and an inner cylinder 7 are provided in the housing 5. An adjusting rod 9 is screwed into the inner cylinder 7. The sprocket 6 is rotated by the composite gear 4 through operation of the motor assembly to expand or contract the inner cylinder 7 with the adjusting rod 9. An outer cylinder 8 fitted on the inner cylinder 7 is provided at the housing 5. One end of the outer cylinder 8 is rotatably connected to the housing 5 and the other end is fastened to the adjusting rod 9. When the outer cylinder 8 is manually rotated, the adjusting rod 9 rotates together with the outer cylinder 8. One end of the adjusting rod 9 is threadedly engaged with the inner cylinder 7. Further, the outer cylinder 8 and the adjusting rod 9 can slide relative to each other and thus the adjusting rod 9 expands or contracts in an axial direction through effect of a spiral structure.SELECTED DRAWING: Figure 2

    【課題】アジャスティングロッドの伸縮調整をモータ駆動構造とともに、手動により調整可能な構造とし、安定性の高い自動車のヘッドライトレベリング装置を提供する。【解決手段】筐体5を備え、筐体5内にモータ組立体2、複合歯車4、スプロケット6及び内筒7が設けられ、内筒7内にアジャスティングロッド9が螺嵌され、モータ組立体運転により複合歯車4でスプロケット6を回転させることで、内筒7をアジャスティングロッド9と共に伸縮させる。筐体5にも内筒7を外嵌する外筒8が設けられ、外筒8の一端は筐体5に回転可能に連結され、他端はアジャスティングロッド9と緊合し、外筒8を手動で回転させた時、アジャスティングロッド9も一緒に回転し、アジャスティングロッド9の一端が内筒7と螺嵌し、かつ外筒8とアジャスティングロッド9との間は相対的に摺動できるため、螺旋構造の作用によりアジャスティングロッド9は軸方向に伸縮する。【選択図】図2
