Abstract:
1. A connecting device for connecting a wiper blade to a wiper arm, the connecting device comprising: a hinge unit formed at one end of the wiper arm, to an other end of which is connected a wiper arm head to which rotational force is transmitted; and an adapter provided at an upper end of the wiper blade so that the adapter is coupled to the hinge unit of the wiper arm, wherein the hinge unit comprises retainers disposed opposite to each other about an opening formed at one side of the wiper arm so that the opening is defined between the retainers, the retainers having a pin transversely disposed therebetween, the adapter comprises a guide for guiding the pin and a coupling hole connected to the guide so that the pin is hingedly coupled into the coupling hole, and connection between the wiper arm and the wiper blade is achieved by sliding a projecting jaw projecting downward from an upper end of the coupling hole of the adapter along an inclined plane formed at an outer circumference of the pin of the hinge unit and rotating the wiper blade so that one side of the adapter coincides with an inside of the opening in a state in which the pin is hingedly coupled in the coupling hole, wherein the inclined plane of the pin is provided at opposite ends thereof with first step jaws disposed in tight contact with opposite sides of the projecting law to guide the projecting jaw, and wherein the pin further comprises stoppers extending from the first step jaws so that the stoppers protrude in a direction in which the inclined plane is cut, and the stoppers are disposed in tight contact with the upper end of the coupling hole of the adapter to restrict a rotating direction of the adapter to only one direction to prevent a back of the adapter from coming into tight contact with the inside of the opening.
