An actuator assembly includes a first part ( 2 ), a second part ( 3 ), the second part ( 3 ) including a guide ( 5,6 ) for guiding motion of the first part ( 2 ) relative to the second part ( 3 ), and means ( 10,11; 16 - 18; 20 - 22; 24 - 27 ) for generating a driving force between the first part ( 2 ) and the second part ( 3 ) along the guide(s) ( 5,6 ) in response to a driving current. The actuator assembly includes means ( 5,6,10; 16,18; 21,22; 24,25,27 ) for providing a force transverse to the guide ( 5,6 ), acting to hold at least one surface part of the first part against a surface of the guide ( 5,6 ). |
