A windshield wiper includes a primary frame member and secondary frame members coupled to the primary frame member. The primary frame member is in the form of an inverted U-shape and includes end portions in which mounting holes are formed. Each secondary frame member has symmetrically arranged wall plates and a positioning section formed between and slightly projecting beyond the wall plates. Each wall plate forms open-ended slots that are symmetrically arranged. A boss is formed on an inside surface of each wall plate between the open-ended slots. The primary frame member has side plates that are fit over the positioning section of the secondary frame member to have the wall plates of the secondary frame member covering and clamping the vertical side walls of the primary frame member. The bosses are fit into the mounting holes of the primary frame member.
