ABSTRACT:
A windshield wiper for automobiles is disclosed. The wiper allows the wind to smoothly pass through the wiper frame while reducing wind resistance, thereby being stably kept on the windshield. The wiper has a spoiler part and a vent opening at both side portions of the frame's top wall, thus being free from any interference between a wiper arm and the wiper frame while mounting the wiper arm to the wiper frame. Both the spoiler part and the vent openings are individually formed by cutting the frame's top wall from corner to corner, thus being free from any corner causing a vortex of air. The frame's upper side wall has a width of less than that of the lower side wall, thus forming a gap helping to keep the wiper on the windshield. A reinforcing rib is formed between the spoiler parts and a reinforcing rib is also formed between the vent openings, thereby improving the strength of the wiper frame.
