To provide an optical axis adjustment screw and a vehicle lighting equipment, with which the optical axis of the vehicle lighting equipment may be adjusted around multiple axes without moving a manual tool such as a screwdriver significantly.SOLUTION: A screw insertion hole 3c is provided on a lamp body 3. An optical axis adjusting screw 14 composed of a cylindrical outer member and an inner member inserted into the outer member is inserted from the outside of a lamp chamber 4 into the inside of the lamp chamber 4. A turntable 6 meshes with a gear part of the inner member of the optical axis adjusting screw 14 and a second bracket 12 that is screwed with a screw part of the outer member of the optical axis adjusting screw 14 are arranged in the light chamber 4. When the inner member is rotated, the turntable 6 is rotated, the light source unit 5 is rotated around a first axis. When the outer member is rotated, the second bracket 12 is moved in the front-rear direction of the lamp, and a light source unit 5 is rotated around a second axis orthogonal to the first axis.SELECTED DRAWING: Figure 2
【課題】ドライバー等の手動工具を大きく移動させる必要なく、複数の軸周りに車両用灯具の光軸調整ができる光軸調整ネジおよび車両用灯具を提供する。【解決手段】灯具ボディ3にネジ挿通穴3cを設け、灯室4外部から灯室4内部へ、筒状の外側部材と外側部材に挿通された内側部材から構成された光軸調整ネジ14を挿通する。灯室4内部に光軸調整ネジ14の内側部材のギヤ部と噛み合うターンテーブル6と、光軸調整ネジ14の外側部材のネジ部と螺合する第二ブラケット12を配置する。内側部材を回転させると、ターンテーブル6が回転し、光源ユニット5が第一軸周りに回転し、外側部材を回転させると、第二ブラケット12が灯具前後方向に移動し、光源ユニット5が第一軸と直行する第二軸周りに回転する。【選択図】図2
