<p>The device (100) has internal gears (130A,130B) that are in internal engagement with external toothed wheel (120A,120B). The toothed wheel is arranged on outer periphery of vibration generating structure (104). An adjusting element (150) for adjusting the movement of the toothed wheel between fixed wall (136) and side link (138) in axial direction, is arranged on outer periphery of the toothed wheel. The friction coefficient between adjusting element and side link is set less than friction coefficient between end surfaces (120AC,120BC) of toothed wheel and side link.</p> |
