PROBLEM TO BE SOLVED: To provide a function excellent in usability as a sun shade.SOLUTION: A dimmer part 38 is provided in a front glass 18, is able to form a low light transmission area 50 having a width W2 along a vertical direction of a vehicle 10, extending in a belt form in a direction orthogonal to the width W2 and functioning as a sun shade reduced in light transmissivity, and is able to adjust the width W2 of the low light transmission area 50. When respective portions of detection light beams 52 emitted toward a driver seat side light receiving part 44A and a front passenger seat side light receiving part 44B from an infrared light emitting part 42 are intercepted by one finger F of a vehicle seat occupant, a position specifying part 48B specifies the position of the finger F along the vehicle vertical direction near the window glass on the basis of the respective detection results of the driver seat side light receiving part 44A and the front passenger seat side light receiving part 44B. The control part 48C controls the dimmer part 38 such that the lower end of the width W2 of the low light transmission area 50 is located in a position corresponding to the position of the finger F specified by the position specifying part 48B.SELECTED DRAWING: Figure 1
【課題】日除けとして使い勝手に優れた機能を提供する。【解決手段】調光部38は、フロントガラス18に設けられ、車両10の上下方向に沿った幅W2を有し幅W2と直交する方向に帯状に延在し光透過度が低減された日除けとして機能する光低透過領域50を形成可能で光低透過領域50の幅W2が調整可能である。位置特定部48Bは、赤外線発光部42から運転席側受光部44Aと助手席側受光部44Bに向けて照射された検出光52の部分が乗員の1本の指Fで遮られた場合に、運転席側受光部44Aと助手席側受光部44Bの検出結果に基いて窓ガラスの近傍箇所で車両上下方向に沿った指Fの位置を特定するものである。制御部48Cは、位置特定部48Bで特定された指Fの位置に対応する位置に、光低透過領域50の幅W2の下端が位置するように調光部38を制御する。【選択図】図1
