| 发明名称 | Vehicle headlamp and projection lens mounting method | ||
| 摘要 | A vehicle headlamp includes a light source configured to emit light, a reflector configured to reflect the light, a projection lens through which the light is projected, and a lens holder holding the projection lens. The projection lens has a positioning portion, and the lens holder is formed with a jig insertion hole at a location corresponding to the positioning portion in a direction around an optical axis of the projection lens such that the positioning portion is visible through the jig insertion hole. When mounting the projection lens to the lens holder, a positioning jig is inserted through the jig insertion hole and is engaged with the positioning portion to position the projection lens in the direction around the optical axis of the projection lens. | ||
