PURPOSE: A linear actuator is provided to improve mobility and reduce noise and vibration. CONSTITUTION: A body has an accommodating hole along a shaft core. The first protrusion part is formed to have a partial arc shaped section on an end thereof. At least the first protrusion part region is accommodated within the accommodating hole. The second protrusion part is protruded to have a partial arc shaped section on an end thereof. An air gap is formed between the first protrusion part, and the plunger(51) is accommodated within the accommodating hole where the magnetic plunger(51) is movable. A coil(27) is wound on circumferential regions of the plunger and the core and generates a magnetic flux passing through the core and the plunger. A rotary guide unit rotary guides one or more of the core and the plunger to a moving shaft line in a horizontal manner when the core and the plunger approach together or are distanced from each other. A bobbin is interposed between the core and the plunger and the coil and permits the coil to be wound thereon.
