A stopper member is included in a linear actuator comprising a stator assembly, a rotor assembly, an output shaft, and a stopper pin which is fixedly disposed at a frontward portion of the output shaft, and which is adapted to axially control the mode and amount of movement of the output shaft initiated by rotation of the rotor assembly. The stopper member is disposed fixedly with respect to the stator assembly and stops the axial movement of the output shaft without making it happen that the stopper pin which moves together with the output shaft touches the rotor assembly.
