The present invention relates to a linear actuator which simplifies a 4H/4L mode switching structure of a transfer case, and enables an accurate switching of the 4H/4L mode. The linear actuator comprises: a spool-shaped bobbin; a coil wound on an outer surface of the bobbin; a core coupled through the bobbin, having a working space; a yoke coupled to a top of the bobbin, having a guide hole; a plunger installed in the working space to be moved; a rod coupled through the plunger, protruding to the outside through the guide hole; a spring installed between the core and the plunger, elastically supporting the plunger upward; a holder formed on the circumference of the bobbin, having a connector on one side; and a case which surrounds the holder. |
