<p>PURPOSE: To prevent an adjusted optical axis from going out of alignment and to prevent damage of lights. CONSTITUTION: An adjust screw 2 is equipped with a mount part 21 of a first end part having no parts projecting outward from an outer surface of a lamp housing 10 and mounted to the lamp housing 10 rotatably and untransferably in the axial direction. The mount part 21 is equipped, on its end face, with an egagement part 23 with which a tool 3 engages for transmitting torque of the tool 3 to the adjust screw 2. The lamp housing 10 is equipped, in a position opposite to the engagement part 23, with an opening part 109 for engaging the tool 3 with the engagement part 23. As a result of this, it is possible to prevent risks that an adjusted optical axis goes out of alignment or lights, etc., gets damaged by a battery, etc., hitting against the mount part 21 of the adjust screw 2 when the battery, etc., is brought in or brought out, since the mount part 21 of the adjust screw 2 has no parts projecting outward from the outer surface of the lamp housing 10.</p> |
