(54)	Lock with deadbolt actuatable by an electric motor by way of a reduction gearset or a cylinder

(57) A lock provided with a deadbolt (8) that can be actuated electrically by an electric motor (10) through a reduction gearset (12-16) and manually by a cylinder (82), the gearset comprising a gear (16) that is provided with elements (26, 27) for driving the deadbolt by successive turns of the lock and is adapted to actuate an element for blocking the deadbolt (75), at right angles to the direction of the sliding of the deadbolt, characterized in that the driving elements (26, 27) are actuated between a position in which they drive the deadbolt and a position in which they do not drive it by actuation means (39, 40) controlled by the cylinder (82).
