Beschreibung
Zusammenfassung:	A screw actuator, particularly for a brake calliper, comprising a housing ( 1 ), a screw mechanism ( 4 ) with a screw ( 6 ) and a nut ( 5 ), one of which is rotatably supported with respect to the housing ( 1 ), a motor ( 7 ) which is drivingly connected to the screw mechanism ( 4 ), a mechanical locking device comprising a pawl member ( 41 ) and a rotatable member ( 42 ) connected to a rotatable component of the motor ( 7 ) and/or the screw mechanism ( 4 ), and a mechanical or electromechanical control mechanism for displacing the pawl member ( 41 ) between a locking position and a free position. A gear reduction mechanism ( 20 ) is provided, one of the gear wheels ( 42 ) thereof carries teeth ( 45 ) for engaging with the pawl member ( 41 ).
