Technical Field
The present application relates to a wiper device, and more particularly, to a wiper for a vehicle window and a wiper arm thereof.
Background
The wiper for the vehicle window includes a wiper arm driven by an electric driver to reciprocate and a wiper blade detachably mounted to an end of the wiper arm so as to be driven by the wiper arm to wipe the window to clean the window, thereby maintaining the clarity of the window. In order to maintain a sufficiently large clear area, the wiper blade must be sufficiently large. However, the wiper is too large in appearance, not beautiful, and not safe when exposed to glass. In addition, the position of the wiper is also generally a position suitable for disposing other components, for example, this position is also suitable for disposing a glass cleaning liquid ejection head, a camera, and the like. Wipers tend to obstruct the arrangement of these components.
