A wiper blade comprising:
- a rubber blade that wipes a wiping surface, wherein the rubber blade includes a base and at least one attachment groove, which extends in a longitudinal direction;
- at least one backing having a predetermined rigidity and including a central part outwardly curved opposite to the wiping surface, wherein the backing is formed from a spring material and fitted into the attachment groove of the rubber blade;
- and
- an elongated holder member including a longitudinally central part coupled to a distal portion of a wiper arm, a first end and second end, which are arranged at two longitudinal sides, and a first holding portion and second holding portion, which are respectively arranged at the sides of the first end and the second end, wherein the first holding portion and the second holding portion hold the base of the rubber blade, wherein
- the rubber blade projects in the longitudinal direction from the first and second holding portions of the holder member thereby forming a following end portion that follows a curve of the wiping surface, and
- the holder member includes two contact wall portions extending outward in the longitudinal direction from at least one of the first holding portion and the second holding portion and respectively contacting two side surfaces of the following end portion.
