To provide a technology for reducing a risk that a vehicle drives onto a detection device while maintaining a range in which intrusion of foreign matters is detectable at a necessary size, for a device that detects intrusion of foreign matters into a lower part of a vehicle via detection light.SOLUTION: A foreign matter detection device comprises: an optical transmitter which emits detection light toward a retroreflective target mounted on a bottom face of a vehicle body of a vehicle in a direction which is inclined relative to a vertical direction; and a light receiving sensor for receiving detection light reflected by the target. The foreign matter detection device is arranged on a side face of a movable device mounted on a ground surface so as to be located at a position closer to a center line of the vehicle in a lateral direction than to the target.SELECTED DRAWING: Figure 2
【課題】車両の床下への異物の侵入を検出光によって検出する装置において、異物の侵入を検出できる範囲を必要な広さに保ちつつ、検出装置への車両の乗り上げの恐れを減らすための技術を提供すること。【解決手段】異物検出装置は、車両の車体の底面に搭載される回帰反射性のターゲットに向けて垂直方向に対し傾斜した方向に検出光を照射する光学発信機と、ターゲットによって反射される検出光を受光する受光センサと、を備える。異物検出装置は、地面に設置された可動式の装置の側面に、ターゲットよりも車両の横方向の中心線に近い位置となるように配置される。【選択図】図2
