<p>The apparatus has a see-saw (16) that is swivelable by a drive arrangement in an oscillatory pivoting movement about a see-saw axis (23). A gear unit provides power transmission chains between the see-saw and an output unit (4) of a motor. The drive arrangement has exactly one power transmission chain or the set of power transmission chains running parallel to each other and acting in a common mode on the see-saw.</p> |
