To provide a projector which prevents glare from the irradiation light of a turn signal lamp, and suppresses a reduction in the brightness of a projected light pattern.SOLUTION: A long-distance side projection unit 2 which is mounted on a vehicle and projects a prescribed long-distance side light pattern at a relatively-long-distance position on a surrounding road surface, and a short-distance side projection unit 3 which projects a prescribed short-distance side light pattern at a relatively-short-distance position are disposed in a housing 100. The long-distance side projection unit 2 and the short-distance side projection unit 3 comprise projection lenses 24, 34 for projecting the respective light patterns. At least the projection lens 24 of the long-distance side projection unit 2 is arranged at a position that is retracted in a projection direction relative to the projection lens 34 of the short-distance side projection unit 3.SELECTED DRAWING: Figure 4

    【課題】ターンシグナルランプの照射光に対するグレアを防止するとともに、投影する光パターンの明るさの低下を抑制した投影装置を提供する。【解決手段】車両に搭載され、周囲の路面の相対的に遠距離の位置に所定の遠距離側光パターンを投影する遠距離側投影ユニット2と、相対的に近距離の位置に所定の近距離側光パターンを投影する近距離側投影ユニット3がハウジング100内に配設される。遠距離側投影ユニット2と近距離側投影ユニット3はそれぞれ光パターンを投影するための投影レンズ24,34を備えており、少なくとも遠距離側投影ユニット2の投影レンズ24は、近距離側投影ユニッ3トの投影レンズ34よりも投影方向に対して後退された位置に配置される。【選択図】図4
