ABSTRACT:
The invention relates to a gear drive unit (10), in particular to adjust moveable parts in a motor vehicle, with a gear housing (15) and a shaft (18) positioned therein along a longitudinal axis (30), which shaft is supported on the housing (15) via an axial stopping face (35) on a counter stopping face (36), wherein at least one of the stopping faces (35, 36) is inclined perpendicular to the longitudinal axis (30) against a plane (42) by an angle of inclination (40) in order to generate an axial force, and a component (44), which cooperates with at least one of the stopping faces (35, 36), is arranged in a displaceable manner perpendicular to the longitudinal axis (30). In doing so, the coefficient of friction between the at least one stopping face (35, 36) and the component (44) is greater than the tangent of the angle of inclination (40).
