Abstract
The invention relates to a gear motor () for a motor vehicle wiper system including an electric motor () including a rotor () and a rotation shaft () fixed to the rotor, a reduction gear mechanism () including a worm/worm wheel system, a device for generating an axial load configured to offset axial play of the rotation shaft (), including a retaining wedge () mounted in a sliding manner in a radial direction of said rotation shaft (), said retaining wedge () exerting an axial load on the outer race of a ball bearing () configured to guide the rotation shaft. According to the invention, said retaining wedge () is arranged in an intermediate position between the seat () of the bearing support () and the worm () directly adjacent to the worm wheel (), said axial load (Fa) exerted by the retaining wedge () on the outer race () of the ball bearing () being in the direction away from the worm ().
