Abstract: Disclosed herein is a wiper lever assembly which is configured to prevent detachment of end cover members, which includes a lever member (a center cover lever, secondary levers and yoke levers) gripping a rubber blade disposed thereunder, and an end cover member which covers an end of the lever member from above and which includes claws formed on both lateral sides thereof. The claws may be extended inwardly from the end cover and engage with both lateral sides of a lower surface of the lever member to grip the lever member. The end cover member includes a support wall which is formed at the center of a width of the end cover member and is extended downwardly therefrom, and the lever member includes a receptor (an insert tube and a proximal insert tube) in which the support wall is fitted from above.

Abstract: Disclosed is a wiper lever assembly that includes upper and lower levers, a plurality of pivotal connecting parts that are pivotally coupled to a longitudinal end of the upper lever, and a plurality of mating pivotal connecting parts that are disposed on the lower lever. The assembly further includes an upper pressing arc portion disposed on the upper lever over the plurality of pivotal pressing parts. The upper pressing arc is in slidable contact with a lower engaging arc portion disposed on the lower lever. In addition, a radius of curvature of a concave arc of the upper pressing arc portion and the lower engaging arc portion is larger than that of a convex arc of the upper pressing arc portion and the lower engaging arc portion.
