A wiper system 1 has a wiper blade 5 for performing a reciprocating wiping operation on a windshield glass 6 and a brushless motor 2 for causing the wiper blade 5 to perform the reciprocating wiping operation. The motor used as the brushless motor 2 is provided with a rotary shaft for reciprocating the wiper blade 5, 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 blade 5 operates at error angles different in direction between during a forward-path wiping operation and during a return-path wiping operation. When the wiper blade 5 reaches a reversing position, the brushless motor 2 is made to rotate about an axis extending in a extending direction of the wiper blade 5 to change the error angle .

Vehicle windshield wiper device

A vehicle windshield wiper device comprising an articulated structure and a blade, the articulated structure comprising an arm transmitting mechanical forces to the blade, wherein the arm is mounted on an axle to provide an arm rotational movement corresponding to a wiping movement, wherein the arm is pivotably attached to the axle. The vehicle windshield wiper device also comprises an arm holder restraining the arm from pivoting when blade is in a parking position.
