<p>The present invention discloses a wiper blade. The wiper blade comprises a frame type long strip skeleton, a connector to be connected to a wiper arm of an automobile and a rubber strip supported by the long strip skeleton. The long strip skeleton includes one elastic main beam. In a free state, a body of the main beam has a curved locus in which a specific smoothly continuous curve is concave downward, both end portions of the main beam register with said curved locus and a middle portion of the main beam registers with said curved locus or deviates from said curved locus. The long strip skeleton further includes one or two elastic sub beams which are located below the main beam and are approximately parallel to the main beam. In the long strip skeleton, the rubber strip is supported by the sub beams. A plurality of hanging hooks which are provided to the main beam connect the sub beams to the main beam. Between the main beam and the sub beams is provided a means to constitute various frame structures or to adjust a distance between them so that the pressure applied along the entire length of the wiper blade to a windshield glass of the automobile by the wiper blade can be distributed evenly as far as possible.</p> |
