Abstract
An object of this invention is to provide a wiper device of a vehicle capable of preventing foreign matter from being caught in a link mechanism of a four-articulation link system type wiper arm, capable of maintaining its function under severe conditions and of being realized through a simple structure at low cost. This wiper device of the vehicle is of the four-articulation link system in which a main lever and a sub lever are each connected to an arm head. A cover member is mounted on the arm head with engaging pieces and engaging concave portions. The cover member covers a link mechanism portion. A mesh-like rib is formed at a back side of the cover member so as to improve rigidity. As a result, it is possible to block penetration of snow or the like and remove (wipe off) accumulated snow and formed ice by force, thereby preventing an increase in the accumulated snow.
