To provide a blade spring which can make a moving piece reciprocate properly extending over a long period of time.
The blade spring 16 elastically supports a stator 12 and the movable piece 15 coaxially and concentrically of a linear actuator with reciprocating motion to be performed, the blade spring comprises an inner circumferential part 16a connected to the stator 12 or the movable piece 15, an outer circumferential part 16b formed at the outer periphery of the inner ring shaped part 16a, and an arm 16c connecting the inner circumferential part 16a and the outer circumferential part 16b in the inner region of the outer ring-shaped part 16b in its internal region to be deformed elastically with the stator 12 or the movable piece 15 so as to undergo reciprocating motion.
