    • A vehicle headlamp of the present invention is provided with a lamp housing and a leveling device. The lamp housing has: a mount portion in which a circular through hole is provided; and an abutment protrusive portion which is provided at the mount portion. The leveling device has: a housing for providing a cylinder portion which is inserted into the circular through hole, and is mounted at a rim of the circular through hole; and an abutment face protrusive portion which is provided partly of the housing and allows the abutment protrusive portion to be in abutment against. As a result, the vehicle headlamp of the present invention allows the abutment protrusive portion to be in abutment against the abutment face protrusive portion, making it possible to ensure a stable distance between the lamp housing and the leveling device.
    • 本发明的车辆前照灯设置有灯壳体和调平装置。 灯壳具有:设置圆形通孔的安装部分; 以及设置在安装部分处的邻接突出部分。 平整装置具有:用于提供插入到圆形通孔中的圆筒部分并且安装在圆形通孔的边缘处的壳体; 以及抵靠面突出部分,其部分地设置在壳体上并且允许邻接突出部分抵靠。 结果,本发明的车辆用前照灯能够使抵接突出部抵接在抵接面突出部上,能够确保灯壳与调平装置之间的距离稳定。
