Abstract
This vibration actuator has a movable body having a coil, a fixed body having magnets, and a shaft part that rotatably supports the movable body, wherein the movable body reciprocally and rotationally vibrates around the shaft part with respect to the fixed body through the interaction of the coil and the magnets. The magnets are arranged in a direction perpendicular to the axial direction of the shaft part and each have two magnetic poles that face the movable body in the coil axial direction of the coil, the shaft part supports the movable body at a position shifted from the center position of the movable body in a direction perpendicular to the axial direction of the shaft part, and the coil axis of the coil of the movable body is located at a position facing a switching position of the magnetic pole of the magnet.
