The present invention relates to a rubber blade provided in a vehicle wiper blade to wipe the glass surface by receiving the pressure and wiping movement of a wiper arm and, more specifically, to a rubber blade that includes one or more wiping parts for wiping a glass surface, one or more bending parts, and a fixing part for allowing the wiper part to adhere to remain bent at an appropriate rotation angle around the bending part. A fixing point and a fixing surface at an appropriate angle are placed in the fixing part, and a stop surface corresponding to the fixing point is formed on the upper side of the wiping part. Even when excessive pressure is applied to the wiper blade, the contact angle of the glass surface of a wiping contact part is prevented from being excessively reduced by changing the rotation angle of a wiping center part due to the change in position of a contact part due to the angle of the stop surface that is in close contact with the fixing point when the wiping part is bent and rotated.

    본 발명은 차량용 와이퍼블레이드에 구성되어 와이퍼암의 압력과 와이핑 운동을 전달받아 유리면의 닦임을 수행하는 고무블레이드로서, 더욱 상세하게는 유리면을 닦아내는 한 개 이상의 닦임부와, 한 개 이상의 꺾임부와, 꺾임부를 중심으로 닦임부가 적절한 회전 각도로 꺾임이 유지되도록 밀착시켜주는 고정부가 포함된 고무블레이드에 있어서, 고정부에는 적절한 각도의 고정점과 고정면을 위치시키며, 닦임부의 상부 측면에 고정점에 대응하는 정지면을 형성시켜, 와이퍼블레이드에 과도한 압력이 걸리는 경우에도 닦임부의 꺾임 회전 시 고정점에 밀착하는 정지면의 각도로 밀착부의 위치 변화에 의한 닦임중심부의 회전 각도 변화를 통하여 닦임접촉부의 유리면 접촉각이 과도하게 작아지지 않도록 구성된 고무블레이드에 관한 것이다.
