Abstract:
1. Gear drive unit, to adjust moveable parts in a motor vehicle, comprising a gear housing and a shaft positioned therein along a longitudinal axis, the shaft being supported in the housing via an axial stopping face and a counter stopping face, wherein at least one of the stopping faces is inclined in respect to a plane surface that is perpendicular to the longitudinal axis by an angle of inclination in order to generate an axial force, wherein a component, which cooperates with at least one of the stopping faces, is displaceable perpendicular to the longitudinal axis by means of an elastic element that is a bent punched part of the component, such that the component and the element are monolithic, and the component is wedge-shaped and causes the elastic element to displace in a radial direction with respect to the shaft thereby maintaining an axial force to eliminate shaft longitudinal play.
