PROBLEM TO BE SOLVED: To provide a screen wiper driving device that enables a production cost to be reduced in regard to a design, specific to a wide variety of vehicles, of the screen wiper driving device.SOLUTION: A protection circuit 10 within a screen wiper driving device 1 comprises a parallel circuit having two circuit elements 16 and 17. The one circuit element 16 is composed of a capacitor 18, and the other circuit element 17 is composed of a series connection between a diode 19 and a Zener diode 20. The diode 19 and the Zener diode 20 are different in conduction direction from each other. The Zener diode 20 is suppressed in an anodic direction.SELECTED DRAWING: Figure 1

    【課題】スクリーン・ワイパー駆動装置の多種多様な車両特有の設計に対し、生産コストの削減を可能にするスクリーン・ワイパー駆動装置を提供する。【解決手段】2つの回路素子16、17を有する並列回路からなる、スクリーン・ワイパー駆動装置1内の保護回路10に関し、一方の回路素子16がキャパシタ18からなり、他方の回路素子17がダイオード19とツェナー・ダイオード20との直列接続からなり、ダイオード19とツェナー・ダイオード20の伝導方向が異なり、ツェナー・ダイオード20が陽極の方向に抑制する。【選択図】図1
