• a worm gear wheel;
• a worm gear shaft rotatable about an axially extending rotation axis, said worm gear shaft mounted on one side of said worm gear wheel through a first rotary bearing and on an opposing side by a second rotary bearing;
• said first rotary bearing pivotable relative to the housing about a pivot axis perpendicular to the rotation axis;
• a return element between said first rotary bearing and said housing and supporting said first rotary bearing on said housing in the axial direction;
• and
• a ring disposed between a casing face of said first rotary bearing and the housing, said ring having a plurality of tangentially spaced, elastic radial protrusions, each protrusion extending between and engaging said housing and a casing face of said first rotary bearing.
