<P>PROBLEM TO BE SOLVED: To prevent reverse rotation of a wiper drive motor even if an external force acts under open state of a wiper drive circuit. <P>SOLUTION: In a counter wipe wiper system, wiper blades fixed to right and left wiper arms being driven through independent motors are overlapped vertically. Output shaft 35 of a motor 3a or an armature shaft 33 is provided, between the motor 3a and the wiper arm, with a one-way clutch 39 for transmitting rotation in a predetermined rotational direction preset for the motor 3a and preventing reverse rotation of the motor 3a due to rotation reverse to rotation in the predetermined rotational direction being inputted from the wiper blade side. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
