A backing of a wiper blade (53) is virtually divided into a plurality of regions in a longitudinal direction of the backing. A wiping area (B) of the wiper blade (53) in a glass surface (50a) is discretized in a wiping direction (x direction) of the wiper blade (53) and in a longitudinal direction (z direction) of the wiper blade (53). A curvature of each of the plurality of virtually divided regions of the backing is set in such a manner that a sum of variation differences of contact pressures (Fyij) at respective discretized points (Pij) is minimized. With such a wiper blade partial pressure setting method, a wiping performance of the wiper blade (53) can be easily and reliably improved over the entire wiping area of the wiping surface. |
