Abstract
A linear actuator includes a supporting unit with a stopper, a linear output unit, a movable unit, a magnetic flux generating unit and a control unit. The movable unit is connected to a stopper of the outer pipe at one end of the outer movable unit and to the linear output unit at the other end. The magnetic flux generating unit generates first magnetic fluxes. The movable unit has elasticity, and expands or contracts based on action of the first magnetic fluxes and the elasticity. The linear output unit linearly moves in response to the expansion or contraction of the movable unit.
