A wiper coupling apparatus is provided to separate a wiper blade with little power by hooking one side of a wiper arm connector to a projection threshold. A wiper coupling apparatus connects a wiper blade(2) to a wiper arm(1). The wiper coupling apparatus includes a blade part(3), and a wiper arm connector(4). The blade part includes a support shaft(31), and a projection threshold(32). The support shaft has a space part formed at a center of the wiper blade. The projection threshold projects from a lower part of one wall of the space part of the support shaft to the other wall. The wiper arm connector is integrally formed with one end of the wiper arm. The wiper arm connector includes an insert groove(41), and a round surface(42). The insert groove is opened to insert the support shaft. The round surface is adhered to the projection threshold. The projection threshold has a corner part in line contact with the round surface of the wiper arm connector. |
