Abstract
PURPOSE: To enable the adjustment of contact pressure of a blade depending on the speed of running, by coupling an arm shank to an arm pressure control unit through an elastic member so that the arm can be moved toward and away from a window glass and by interlocking the control unit with a vehicle running speed detection unit.
CONSTITUTION: In a vehicle speed detection unit 21, the pressure of oil or air in the chamber of a cylinder 23 is changed in response to the speed of running to move a piston 22 depending on the speed. In rapid running, the piston 22 is moved up to elevate the rod 12 of an arm pressure control unit 11 and swing a hood 14 counterclockwise centering a pin 13 to elongate a spring 9. This results in heightening a thrusting force on the wiping surface of an arm shank 6 pivoted by a pin 7 to an arm support 5 on an arm driving shaft 4. In slow running, the piston 22 is moved down to reduce the thrusting force on the wiping surface of the arm shank 6.
