According to embodiments of the present invention, a wiper blade wiping a glass surface comprises a wiper strip having the shape of extending in a longitudinal direction, and the wiper strip comprises a wiping lip of which an external side surface of a cross section cut into a virtual plane vertical to a longitudinal direction forms an arc in at least a portion. Therefore, a contact form of the glass surface and the wiping lip can be close to line contact, thereby preventing an increase in a frictional force between the glass surface and the wiping lip to reduce vibration and noise that may occur when wiping the glass surface.

    본 발명의 실시예들에 따른 유리면을 와이핑하는 와이퍼 블레이드는길이방향으로 연장된 형태의 와이퍼 스트립을 포함하고, 와이퍼 스트립은 길이방향에 수직하는 가상의 평면으로 자른 단면의 외측면이 적어도 일부 영역에서 원호를 형성하고 있는 와이핑립을 포함한다. 따라서, 유리면과 와이핑립의 밀착형태를 선접촉에 가깝도록 할 수 있어서, 유리면과 와이핑립 사이의 마찰력 증가를 방지하여 유리면을 와이핑할 때 발생할 수 있는 진동이나 소음을 감소시킬 수 있다.
