Abstract

PURPOSE:To prevent the chattering noise of a wiper blade from occurring, by putting a nick in an edge part of the wiper blade. CONSTITUTION:A nick 3 is being put in an edge part 2 of a wiper blade 1. Since the nick 3 is put in the edge part 2, any strain to be imposed on the edge part 2 is eliminated, so that chattering noises and wipe unevenness are preventable.

、この波形をエツジ部から取り除き、びびり音や拭きむ
らを解消する方法が望まれている。Conventionally, even new wiper blades sometimes produce chattering noises or uneven wiping when they move from side to side in a fan-like manner across the front surface. The reason for this is that when the tip of the edge part, which has a thickness and length as shown in Fig. 1, is bent to the left as shown in Fig. 2, it will shrink because it is made of rubber, but one side of the shortened part (in this case A waveform is generated on the left side). This is a phenomenon that occurs when an object of a certain length is shrunk and the length is physically adjusted by creating a curve or waveform to accommodate the shortened length. Therefore, even if there is a difference in size at the edge of the wiper blade, which is the contact point with the windshield, the wiper blade, which is curved and pressed by the spring pressure against the windshield surface that is unevenly curved vertically and horizontally, will form a wave. It is possible that this is occurring. It is this waveform that causes chattering noise and uneven wiping when it lands on and leaves the windshield. Therefore, a method is desired to remove this waveform from the edge portion and eliminate chattering noise and uneven wiping.

本発明は、その欠点を除くためになされたもので、それ
を図面について説明すれば、ワイパーブレード（１）の
エツジ部（２）に切り込み（３）を込れたものである。The present invention has been made to eliminate this drawback, and to explain it with reference to the drawings, a notch (3) is provided in the edge portion (2) of the wiper blade (1).

本発明は、このような構造で有るから、エツジ部に生じ

が有る。しかも、エツジ部に切り込みを入れるという簡
単な構造なので容易に製造することが出来る。Since the present invention has such a structure, the rubber of the edge overlaps at the notch part and absorbs the large and small waveforms due to the strain generated at the edge part, eliminating the unevenness on the edge and preventing chatter. It has the effect of preventing noise and uneven wiping. Furthermore, since the structure is simple, ie, notches are made in the edge portion, it can be manufactured easily.

なお、切シ込みの入れがたとして、第６図のように斜め

出来る。Incidentally, by making the cuts diagonally as shown in FIG. 6, uneven wiping due to the cuts can be prevented.
