ABSTRACT:
A control lever is driven by a driving unit to cause variation in tension of a coil spring and therefore variation in force with which a wiper blade is pressed against a windshield. The driving unit is disposed in an arm head and includes a geared motor, a male screw member in the form of a bolt and secured to an output shaft of the geared motor and a female screw member having an internally threaded socket portion screwed onto the male screw member and a sliding portion in the form of a rectangular bar and installed in a guide member for longitudinal movement but against rotation. The output shaft of the geared motor, male screw member and the female screw member are so arranged as to have axes in line with each other and exending longitudinally of the arm head.
