  • Patent number: 5857236
    Abstract: The present invention provides a wiper apparatus comprising a blade rubber for wiping windshield glass, a wiper blade on which the blade rubber is mounted, a wiper arm which is pivotally supported on a vehicle body and on which the wiper blade is mounted, and a dispersing device. The wiper arm is provided such that a pressing force is applied to the wiper arm so as to cause the blade rubber to contact the windshield glass with a predetermined press contact force. The dispersing device disperses toward the windshield glass the press contact force applied to the blade rubber due to the pressing force of the wiper arm, by the dispersing device and the blade rubber together press contacting the windshield glass at at least one of two reversing positions at which swinging of the wiper arm reverses, so as to reduce the press contact force of the blade rubber against the windshield glass.
