Abstract
Disclosed is a step actuator apparatus. The step actuator includes a step actuator including a housing, a stator installed in the housing, a rotor rotating by a reaction with the stator and a screw member coupled to the rotor and moving linearly according to rotation of the rotor; and a circuit board module including a circuit board electrically connected to the step actuator and a case for supporting the circuit board. The housing has a first opening. The case includes a plurality of hooks inserted into the first opening.
