On the other hand, when considering the cleaning force of the wiper blade, on the contrary, as the wiper blade maintains an angle close to the cleaning surface S at an angle close to the cleaning surface S, the cleaning force is excellent. When the cleaning surface S has a small angle? 1 with respect to the cleaning surface S, the cleaning force is deteriorated and the residual contamination P 'remains.

However, most of the existing inventions do not harmonize the opposite characteristics between the ease of operation and the cleaning force, and they are projected to the lower side of the blade of the blade for automobile wiper (Open Utility Model No. 20-1998-021842) The wiping blade 16 and the wiping blade 16 which are connected to the wiping blade 10 so as to perform direct wiping are formed in two so that the wiping can be performed more smoothly or the wiping blade (Patent Document 10 The wiper blade of the present invention is characterized in that the wiper blade has an insertion groove formed in the longitudinal direction at both upper end portions of the upper end of the wiper blade and a wing for contacting the window of the vehicle at the lower end of the insertion groove and removing water and foreign matter, And the auxiliary vanes are integrally formed downward on both side surfaces of the wing. There was a problem in that fire.

In addition, since the conventional wiping blade wipes the contaminants only by the wiper blade itself, residual contaminants tend to remain due to poor adhesion or damage to the contact portion of the wiper blade.
