Abstract
An oscillatory actuator has: a fixed body that has a planar part and a flat coil disposed on the planar part; and a movable body that has a magnet facing the coil and oscillates in a reciprocating manner in one direction relative to the fixed body above the planar part via cooperation between the coil and the magnet. The fixed body has a pair of linear bearings that are respectively disposed along both side surfaces extending in said one direction of the movable body and are equipped with balls capable of rolling and coming into contact with the respective side surfaces. The movable body is supported via the balls of the linear bearings so as to be able to oscillate in said one direction.
