Abstract
A blade device includes an elongated elastic blade, and a support member, disposed along a longitudinal direction of the elastic blade, for supporting one end of the elastic blade in a direction perpendicular to the longitudinal direction. Lateral end sections of the elastic blade in the longitudinal direction are more protruded than a central section thereof in a direction opposite to the support member. Portions of the support member corresponding to protruded portions of the elastic blade and supporting the elastic blade are retracted toward a direction opposite to a protruding direction of the elastic blade. The support member may be made of different shapes to achieve the retracted configuration. In addition, the support member may be made of two different materials so that portions of the support member have different elasticities.
