Abstract
An oscillatory linear actuator includes: an output movable element which is reciprocated by a periodically varying magnetic field and performs work on an object; and a vibration absorbing movable element which is reciprocated at a phase opposite to a phase of the output movable element and reduces vibration of the oscillatory linear actuator. The vibration absorbing movable element is lighter in weight than the output movable element.
