- 光を前方へ向けて投影する投影レンズと、該投影レンズの後側焦点より後方に配置され光軸方向が前後方向とされた光源と、該光源から出射された前記光を前記投影レンズ側へ向けて反射するリフレクターと、上端縁が前記後側焦点の近傍を横切るように配置されると共に前記光源から出射され前記リフレクターで反射された光の一部を遮蔽し配光パターンを形成するためのシェードとを備えた車輌用前照灯であって、
前記シェードは固定部と該固定部に対して移動される可動部とから成り、
前記可動部が前記固定部に当接する第1の位置と前記固定部から離隔する第2の位置との間で移動され、
前記可動部が前記第1の位置に移動されて第1の配光パターンが形成され、前記可動部が前記第2の位置に移動されて第2の配光パターンが形成され、
前記可動部の前記固定部と当接する端部が当接部として設けられ、
前記固定部の前記可動部が当接される端部が被当接部として設けられ、
前記当接部又は前記被当接部の少なくとも一方の厚みが、前記可動部の前記当接部以外の部分の厚みより厚くされ、
前記固定部の厚みが前記可動部の厚みより厚くされ、
前記可動部が前記第1の位置に移動された状態において、前記シェードが上方及び前方に開口された椀状に形成され、
前記可動部が前記第1の位置に移動された状態において、前記シェードの内面が曲面に形成されて前記固定部の内面と前記可動部の内面とが前記同一曲面上に位置され、
