PROBLEM TO BE SOLVED: To provide a wiper device capable of performing a wiper operation reliably even in the case where a wiper control part (or microcomputer) fails.SOLUTION: A wiper device 1 is constituted to comprise: a wiper lever 10 to be operated by the operator; a magnet 20 (a permanent magnet) disposed at a portion of the wiper lever 10 or on the lower end side in the present embodiment; a magnetic detection unit 30 for detecting the change of the magnetic field resulting from the movement of the magnet; a control part 40 for outputting an on-off signal on the basis of the detection result of the magnetic detection unit 30; a contact switch part 50 for outputting an ON-OFF signal on the basis of the motion of the wiper lever 10; and a wiper drive part 60 for driving a wiper blade 70 on the basis of either the ON/OFF signal of the control part 40 or the ON/OFF signal of the contact switch part 50.
【課題】ワイパ制御部(マイコン)が故障した場合でも確実にワイパ動作ができるワイパ装置を提供する。【解決手段】操作者によって操作されるワイパレバー10と、ワイパレバー10の一部、本実施の形態では下端側に設けられた磁石20(永久磁石)と、磁石の移動による磁界の変化を検出する磁気検出部30と、磁気検出部30の検出結果に基づいてオンオフ信号を出力する制御部40と、ワイパレバー10の動きに基づいてオンオフ信号を出力する接点スイッチ部50と、制御部40のオンオフ信号又は接点スイッチ部50のオンオフ信号に基づいてワイパブレード70を駆動するワイパ駆動部60と、を有してワイパ装置1を構成する。【選択図】図3
