Abstract
A wiper device has an arm support constituting a wiper arm that is provided with a waterproof structure. The waterproof structure protects a link coupling portion of the arm support from water. First and second link coupling portions are provided on a proximal end portion of the arm support. First and second guiding passages are formed between the first and second link coupling portions, and a third guiding passage is formed above the second link coupling portion. Furthermore, locking hooks for mounting a cover that serve also as dripping guide members are provided and disposed at right ends of the first, second, and third guiding passages such that the locking hooks face each other. Thus, water on a surface of the arm support is positively drained toward a window surface.
