Wiper arm equipment to be mounted on a glass surface of a wind shield of a vehicle. A wing of the wiper arm equipment is commonly used in the case of an installation on a production line of the wiper arm equipment and in the case of an optional installation. A pair of insert plates is planted in the wing as an integral part, and a pair of screw holes is bored on each insert plate with predetermined distance. One of the screw holes is arranged in a position facing the arm piece when the wing is to be mounted on the arm piece, and the other screw hole is arranged in a position other than that facing the arm piece. In the case of the optional installation, each pair of stays is fastened with a screw through the other screw hole so as to cover each insert plate.
