A wiper blade, comprising:
- a wiper rubber;
- and
- a lever assembly holding the wiper rubber and coupled to a wiper arm, the lever assembly including a plurality of levers, adjacent levers of which are hinge-jointed to each other,
- wherein one of the adjacent levers includes a spoiler portion forming a section of a spoiler integrated in the one of the adjacent levers and the other of the adjacent levers includes a spoiler portion forming a section of a spoiler integrated in the other of the adjacent levers,
- wherein the one of the adjacent levers includes an arm extending from the spoiler portion of the one of the adjacent levers toward the other of the adjacent levers and holding the wiper rubber at a distal end;
- and a stepped surface formed between the spoiler portion of the one of the adjacent levers and the arm of the one of the adjacent levers,
- wherein the arm of the one of the adjacent levers is situated in the spoiler portion of the other of the adjacent levers,
- wherein a longitudinal outer end surface of the spoiler portion of the other of the adjacent levers faces the stepped surface of the one of the adjacent levers,
- wherein the lever assembly further includes a joint nested on the arm of the one of the adjacent levers and hinge-jointed to the arm of the one of the adjacent levers, the joint being located adjacent to the stepped surface of the one of the adjacent levers,
- wherein the joint is inserted to an inside of the spoiler portion of the other of the adjacent levers and snap-engages the spoiler portion of the other of the adjacent levers,
- wherein the joint has a snap protrusion at a longitudinal inner lower edge and a mating protrusion at a longitudinal outer end surface,
- wherein the spoiler portion of the other of the adjacent levers has a snap notch, to which the snap protrusion is fitted, at a lower edge and a mating notch, which mates the mating protrusion, at the longitudinal outer end surface, and
- wherein when the joint is inserted to the inside of the spoiler portion of the other of the adjacent levers, all portions of the joint except the snap protrusion and the mating protrusion are hidden in the spoiler portion of the other of the adjacent levers.
