Oscillatory linear actuator and cutting device

An oscillatory linear actuator comprising:

• 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,
• wherein the output movable element includes:
• a first driver which generates a thrust force which is reciprocated by a magnetic field;
• a work part which performs work on the object at a predetermined distance away from the first driver;
• a shaft which is coupled to the work part and the first driver;
• a first weight opposite to the work part relative to the first driver;
• and
• a weight support which is coupled to the first driver and the first weight,
• wherein the vibration absorbing movable element includes:
• a second driver disposed parallel to the first driver, and disposed on a line extending from and parallel with the shaft;
• a second weight disposed on a work part side of the first driver;
• and
• a connector which connects the second driver and the second weight, and
• wherein the first weight is disposed at a position farther from the second driver than the second weight is.
