Abstract
A wiper blade apparatus, having a main lever which is formed of synthetic resin, includes a rotation shaft that is disposed at a center of the main lever, and formed to connect both sidewalls of the main lever; and a connector that is rotatably coupled to a rotation shaft, and formed to be detachable from the rotation shaft, wherein a first fool-proof assembly unit is formed at the rotation shaft, and restricts a range of a rotation angle of the connector that prevents misassembly of the connector; and a second fool-proof assembly unit is formed on the coupling unit of the connector and, in correspondence with the first fool-proof assembly unit, restricts a range of a rotation angle of the connector.
