摘要： An elastic blade includes a contact edge to contact a contact object, an edge region including the contact edge and having a thickness smaller than or equal to 0.50 mm, and a backup region different in material or property from the edge region. The backup region is adjacent to the edge region on a cross section perpendicular to a direction in which the contact edge extends. The elastic blade has a converted Martens hardness X (N/mm2) in a range of from 0.9 to 2.9. The converted Martens hardness is defined as: X = S A S A + S B × h A + S B S A + S B × h B where SA represents a cross-sectional area (mm2) of the edge region, SB represents a cross-sectional area (mm2) of the backup region, hA represents a Martens hardness (N/mm2) of the edge region, hB represents a Martens hardness (N/mm2) of the backup region, and t represents the thickness (mm) of the edge region including the contact edge.

摘要： An elastic blade includes a contact edge to contact a contact object, an edge region including the contact edge, and a backup region different in at least one of material and physical property from the edge region and adjacent to the edge region on a cross section perpendicular to a direction in which the contact edge extends. The backup region is free of direct contact with the contact object. In the elastic blade, a converted elastic power X is from 57% to 90% and defined as X = S A S A + S B × e A + S B S A + S B × e B where SA and SB represent cross-sectional areas of the edge region and the backup region on the cross section, and eA and eB represent elastic powers of the edge region and the backup region.

摘要： A multilayered blade made of an elastic material includes an edge layer, having a contact edge to contact an object, and at least one backup layer laminated on the edge layer.The blade has a converted loss tangent tan δ of 0.23 or greater and 0.51 or smaller in a temperature range of from 0° C. to 50° C. The converted loss tangent tan δ is defined as: X = A A + B × L 1 + B A + B × L 2 , where X represents the converted loss tangent tan δ, A represents a thickness in millimeters of the edge layer, B represents a thickness in millimeters of the at least one backup layer, L1 represents a variation of a loss tangent tan δ of the edge layer in the temperature range of from 0° C. to 50° C., and L2 represents a variation of a loss tangent tan δ of the at least one backup layer in the temperature range of from 0° C. to 50° C.
