FIELD: machine building.

SUBSTANCE: invention relates to a wiper blade (10) of frameless design. The blade consists of rubber band (14) with a lug (18) being coupled with the upper part (22) of the rubber band profile by a flexible partition (20), of at least one prebent resilient bar (46) serving as a carrying element, of a connection element and a spoiler (32) having the front profile (34) and the fastening profile (38) with the said front profile (34) being fitted by at least one longitudinal channel (44, 48) with a resilient bar (46) set in it. The fastening profile (38) on its longitudinal sides has free ledges (42) turned inside, set opposite each other and entering the respective longitudinal grooves (24) in the upper part (22) of the rubber band profile. The upper part (22) of the rubber band profile is not fitted by a resilient bar, and, first of all, no resilient bar (46) touches the upper part (22) of the rubber band profile.

EFFECT: better head-on air flow conditions for the wiper blade spoiler due to the possibility to make the blade narrower.
