An operable angle adjusting structure for a wiper producing a maximally wide wiping angle within the range where wiper arms will not interfere with window pillars and each other and will not require a precision machining apparatus. A drive link (7) includes a ball joint (16a) disposed in one end portion, and the ball joint (16a) is integrally mounted to one surface of an adjusting member (16c) such that the center axis (P) of the ball joint (16a) is eccentric with respect to the center of a screw hole (16d) by a distance alpha . The adjusting member (16c) is turned to change the axis-to-axis distance between a wiper drive shaft (6) and the ball joint (6a) for proper adjustment. <MATH> |
