<p>A drive for a locking device on a vehicle door, more especially a motor vehicle door, the drive comprising a motor, on whose driven shaft there is coupled a gear unit which converts the rotary movement of the driven shaft of the motor into a displacing movement of a driven member of the drive which is displaceably guided in the gear case, and comprising a driver clutch, which is provided with play and is operative in both driving directions, between the driven shaft of the motor and the driven member. The driver clutch is provided in the rotary movement force path and comprises two clutch elements (31, 33) which are coaxially mounted in the gear case so as to be rotatable relative to each other. Each of the two clutch elements (31, 33) has respectively one pair of stop faces arranged at an angular distance from each other and point in opposite circumferential directions. The stop faces of one of the two clutch elements (31) have, in pairs, a smaller angular distance from each other than the pair of stop faces of the other clutch element (33) and are arranged in the rotational path between these stop faces. <IMAGE></p> |
