Abstract

The present invention pertains to a step actuator, wherein a motor section being formed of a stepping motor serves as a driving source, a pinion gear is axially coupled with a rotation shaft of the motor section, a gear section is coupled with the pinion gear, and the torque of the motor section is transmitted by an output shaft which is coupled with the gear section. More specifically, the top surface of the motor section has a motor cover mounted thereon which supports the motor rotation shaft and a stopper which restrains the rotation of the gear rotation shaft. Therefore, initial positional accuracy may be improved and the increase of errors caused by the accumulated tolerance of assembly may be minimized when compared with existing step actuators in which a stopper is mounted to a case which is an injection molded component. In addition, the manufacturing and maintaining of components in the process of mass production become simple, thereby saving product manufacturing costs.
