Abstract
A blade rubber has an elongate shape extending along a longitudinal direction. The blade rubber includes a basal portion retained by a rubber holder and a wiping portion extending downward from the basal portion. The wiping portion slidably contacts and wipes a wiped surface along a width direction. The wiping portion has a cross-sectional shape, which inclines with respect to a downward hanging direction when the blade rubber is in an unloaded state. The cross-sectional shape is a shape of a cross-sectional surface of the wiping portion. The cross-sectional surface extends along a direction perpendicular to the longitudinal direction. The downward hanging direction is a direction, which extends along a direction perpendicular to the longitudinal direction and the width direction.
