Abstract
There is provided a wiper arm including a head cover attached to an arm head and securely preventing the head cover from coming off the arm head. A wiper arm (1) includes an engaging protrusion (19) which extends upward and is disposed on a step section (18) formed at a lower end of a dent section (17) formed on a side surface of an arm head (2), and a protruding engagement section (27) formed near a lower end of an inner surface of a side wall (23) of a head cover (4). An opening section (27A) opening downward is formed in the protruding engagement section (27). The engaging protrusion (19) fits into the opening section (27A) along a vertical direction, namely, a direction along the side wall (23). The open end of the side wall (23) of the head cover (4) is thereby prevented from being widened outward so that the head cover (4) is prevented from coming off the arm head (2).
