Title:
WIPER DRIVING CIRCUIT
Document Type and Number:
Japanese Patent JP3855609
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a wiper driving circuit for more safety by constructing a wiper to be surely operated if a wiper relay is melted.
SOLUTION: The wiper driving circuit comprises a wiper motor 12 to be operated with power supplied from a battery 20, a wiper switch 30 for switching the operated condition of the wire motor 12, and first and second wiper relays 40, 60 to be actuated with the operation of the wiper switch 30. A closed circuit is formed so that a movable contact 44 of the first wiper relay 40 abuts an off-contact 46 to make the wiper motor 12 stopped with self power generation when the wiper switch 30 is located at a stop position, whereby power is supplied to the wiper motor 12 via the second relay 60 without passing through the first wiper relay 40 when the wiper switch 30 is located at a drive position.
