Abstract:
1. A wiper blade for connection to a wiper arm for wiping a surface to be wiped while swinging to-and-fro between a wiper stop position and a reversal position, the wiper blade comprising: a single lever member configured to be coupled to the wiper arm, the lever member including first and second retaining hooks arranged at an interval along the longitudinal direction of the lever member; and a blade rubber retained by the lever member, the blade rubber including an accommodating groove open toward a wiping direction, a leaf spring member mounted in the accommodating groove, in which the first retaining hook retains the blade rubber at a first position and the second retaining hook retains the blade rubber at a second position that is different than the first position while preventing the leaf spring member from falling out of the accommodating groove, wherein the lever member includes a plurality of fall-off preventing protrusions each arranged between the first and second retaining hooks in the longitudinal direction of the lever member and located on both sides of a center position between the first and second retaining hooks in the longitudinal direction of the lever member, the fall-off preventing protrusions projecting toward the surface to be wiped and being arranged on a rear side of the blade rubber with respect to a direction in which the blade rubber moves from the wiper stop position toward the reversal position, the fall-off preventing protrusion permitting movement of the blade rubber in the direction perpendicular to the surface to be wiped, and, when the blade rubber moves from the wiper stop position toward the reversal position, the fall-off preventing protrusion receives the blade rubber so as to prevent the leaf spring member from falling out of the accommodating groove.
