Claims

[Scope of utility model registration request]

The tips of the main arm and sub-arm, which are arranged in parallel, are pivotally connected to each end of the connecting link to form a pantograph type wiper arm, and the wiper blade side is connected between both pivoting parts of the connecting link. In the pantograph type wiper arm, each of the arms is pivotally connected to the connecting ring in a state where they are overlapped on the upper surface side of the connecting link. On the other hand, the connecting link is oriented in the left-right direction so as to linearly connect both the pivot joints, and the upper surface of the upper piece of the engagement hook is approximately aligned with the lower surface of the connecting link at the pivot joint. A blade connection structure for a pantograph wiper arm, characterized in that a step is provided on the lower surface of the center of the connection link.
