Abstract
A wiper systemhas a wiper bladefor performing a reciprocating wiping operation on a windshield glassand a brushless motorfor causing the wiper bladeto perform the reciprocating wiping operation. The motor used as the brushless motoris provided with a rotary shaft for reciprocating the wiper blade, has a degree of operation freedom in three axial directions, and is rotatable about axes of two directions orthogonal to the rotary shaft. The wiper bladeoperates at error angles θ different in direction between during a forward-path wiping operation and during a return-path wiping operation. When the wiper bladereaches a reversing position, the brushless motoris made to rotate about an axis extending in a extending direction of the wiper bladeto change the error angle θ.
