A wiper blade comprising a blade main body made of a rubber elastomer and a surface coating layer consisting of a fluorocarbon resin containing reactive groups inside the molecules and a curing agent having reactivity with the reactive groups and provided on the surface of the main body, wherein the surface coating layer is formed on only both sides of the blade main body. Therefore, the wiper has a high flexibility, high recovery properties, a high durability, and a wiping performance without squeal and vibration, and can keep the wiping performance for a long time.

Ce balai d'essuie-glace comprend un corps principal réalisé en élastomère de caoutchouc, ainsi qu'une couche de revêtement superficielle, déposée sur la surface de ce corps et se composant d'une résine fluorocarbone contenant des groupes réactifs dans les molécules ainsi qu'un agent de durcissement réagissant avec lesdits groupes, ce balai étant caractérisé en ce que l'on a déposé ladite couche seulement sur les deux côtés du corps principal. Ainsi, ce balai possède une grande flexibilité, d'excellentes caractéristiques de restauration, une longévité élevée, ainsi que des performances de balayage sans crissement ni vibrations, et il peut conserver ces performances pendant une longue période.
