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: A yoke lever includes an upper wall and two side walls. The upper wall includes an elongated hole, and the side wall includes a pivot coupled portion. A secondary lever includes an insertion coupling portion to be inserted and coupled to the elongated hole from the upper side. The insertion coupling portion includes an insertion tube portion having two opposing side walls, which face the inner surfaces of the side wall of the yoke lever, and two end walls, which connect the longitudinal ends of the opposing side walls. A pivot coupling portion projects from a longitudinally central portion of the opposing side wall to engage the pivot coupled portion while permitting pivoting.

Abstract: An arm piece of a wiper arm, which has a connecting portion connected to a connecting pin through a connecting member received in an opening of a main lever, extends from the connecting portion toward a base end side portion of the main lever such that the arm piece overlaps with an upper surface of the main lever. The main lever is formed by runnerless injection molding. A gate trace, which is left on the main lever in the runnerless injection molding, is formed in an arm accommodation portion of the main lever, which is opposed to the arm piece in a top-to-bottom direction.

Abstract: A wiper blade includes a lever member, a rubber blade, and a movable cover member. The lever member includes a main lever and a yoke lever. The yoke lever includes a plurality of grip portions, by which the rubber blade is gripped. The rubber blade includes a following end projecting outward from the one of the grip portions that is located at a longitudinally outer side of the lever member. The movable cover member includes a holding portion and a basal portion. The holding portion holds the following end. The basal portion is pivotally coupled to the yoke lever so that the movable cover member pivots relative to the yoke lever when the following end bends and deforms in a direction orthogonal to the wiping surface.
