摘要:
A reciprocating linear actuator capable of reciprocatingly driving a plurality of movable elements (2 and 2) by a single stator (1). The movable elements (2 and 2) are connected to each other through a connection body (3) having a spring characteristic to be capable of displacement in the reciprocating direction of the movable element. The connection body (3) has such a shape that can be drawn with a single stroke on a two dimensional plane, and at least both ends thereof are connected to the movable elements (2 and 2), respectively. Since the connection body (3) is made of a flat spring, it requires less space for installation as compared to a connection body formed of a coiled spring. Further, since the entire connection body has an effective spring characteristic, a relatively smaller size is required for the connection body to provide a required spring characteristic. The less installation space for the connection body (3) is advantageous to a reduction in size of the linear actuator.
