Abstract
An actuator for a locking mechanism which locks a shiftable lever in a locked position or a released position. The actuator includes a lock member which is shiftable between a locking position and an unlocking position for causing the lever to be locked in position or to be released from said locking position. A drive mechanism continuously forces the lock member toward said locking position. A drive mechanism causes a rotatable cam to rotate a predetermined distance in a preselected direction. The rotatable cam positions the lock member in the locking position or the unlocking position. The cam is specially designed to permit the lock member in the lock position, to be shifted to the unlocking position against the action of the drive mechanism. The drive mechanism includes a motor for rotating the cam in a predetermined direction, and a control circuit for controlling the power supply to a motor, in order to control the rotational phase angle of the cam.
