PROBLEM TO BE SOLVED: To provide a disconnection detecting device that, when lamps are divided into and set as detection requiring lamps and detection non-requiring lamps, is able to correctly determine respective disconnected states of the detection requiring lamps.SOLUTION: A disconnection detecting device comprises: front lamps 11a, 11b, side lamps 12a, 12b, and rear lamps 13a, 13b, provided on a vehicle; indicator lamps 16a, 16b provided in a vehicle cabin; a power source supply part 110 that supplies power from the power source part 17 to each lamp; and a control section 120 that detects disconnection on the basis of feedback current of each lamp obtained from the power source part. In the disconnection detecting device, the lamps are divided into and set as detection requiring lamps, which require detection of disconnection, and detection non-requiring lamps, which do not require detection of disconnection. The detection requiring lamps are connected to power source circuits 111, 112 serving as the output side of the power source supply part. The detection non-requiring lamps branch on the output side of the power source part and are connected to other power source circuits 115, 116 different from those power source circuits.SELECTED DRAWING: Figure 2

    【課題】検知必要ランプと検知不要ランプとに分けて設定する際に、検知必要ランプの断線状態を正確に判別可能な断線検知装置を提供する。【解決手段】車両に設けられた前方ランプ11a、11b、側方ランプ12a、12b、および後方ランプ13a、13bと、車室内に設けられたインジケータランプ16a、16bと、電源部17からの電力を各ランプに供給する電源供給部110と、電源供給部から得られる各ランプのフィードバック電流に基づいて、断線検知を行う制御部120と、を有する断線検知装置において、各ランプは、断線検知を必要とする検知必要ランプと、断線検知を必要としない検知不要ランプとに分けて設定されており、検知必要ランプは、電源供給部の出力側となる電源回路111、112に接続され、検知不要ランプは、電源部の出力側で分岐し、電源回路とは異なる他の電源回路115、116に接続される。【選択図】図2
