Device with a mounting part of a wiper arm

The device with a fastening component (10) of a wiper arm has a first degree of freedom for the adjustment of the bearing force of the wiper arm. The first degree of freedom is realised by a pivot axis which includes an angle to the longitudinal extent of the fastening component and an angle to the rotational drive axis of the fastening component, the angle in each case being greater than 40 degrees. The pivot axis may be perpendicular to the longitudinal extent and to the rotational drive axis of the fastening component.
