Abstract
【解決手段】投影レンズ22の後方に左右1対の発光素子24L、24Rおよびリフレクタ26L、26Rが配置されたプロジェクタ型の灯具ユニット20Aを、スイブル機構50Aにより水平方向に旋回させる構成とする。その際、光軸Axを含む鉛直面に沿って延びるように配置されるとともに前端縁28bが投影レンズ22の後側焦点Fを通るように形成された両面ミラー片28により、左側のリフレクタ26Lからの反射光の一部を左側方へ、また、右側のリフレクタ26Rからの反射光の一部を右側方へ向けて反射させる構成とする。これにより、左端縁または右端縁の輪郭が明瞭な1対の付加配光パターンの双方または一方を選択的に形成して、これを水平方向に変位可能とする。
