The present invention relates to a step actuator, which is applied to an electronic device used for products, such as vehicles and the like, having a structure of transferring a force in an axial direction by moving a lead screw, which is screw-coupled to a thread formed on an inner circumferential surface of a rotor hollow shaft of a motor unit, forward or backward in the axial direction by rotation of a rotor using the lead screw, and to an electronic device including the same. More specifically, according to the step actuator of the present invention, a bearing is disposed outside a motor unit including a housing, a plate is installed between a lower surface of a mounting member and the outside of one side surface of the housing to fix the bearing, or a plurality of protrusions are formed at the outside in an opposite direction of teeth formed in an inner diameter of the housing to support and fix the bearing, such that a fixing structure of the bearing is facilitated, thereby reducing ...
