Abstract
A linear actuator is provided that has a configuration capable of inhibiting contact between an inner core and a plate spring that is connected to the inner core and an outer core, and which is realized by a configuration that is easy to assemble. A stator is arranged in an opening section of a through-hole in the inner core, and has a spacer through which a shaft passes. An outer frame section of the plate spring is connected to the outer core, and a fixed section of the plate spring is connected to the inner core through the spacer in a state in which the shaft passes therethrough. The spacer includes a penetration section having an insertion hole which the shaft is inserted through, and restriction sections and which restrict a displacement of a predetermined amount or more of the plate spring to the inner core side.
