摘要:
A vibration actuator has a movable body including: a disk-shaped magnet; disk-shaped cores fixed on front and rear surfaces of the magnet and each having an opening at a center thereof; leaf springs having a substantially circular shape; and spring stopper weight parts each having one end positioned by joining the opening to be joined with one of the cores and having another end connected to a central part of one of the leaf springs; and a fixing body including an annular coil having a larger inner diameter than the magnet, the cores and the spring stopper weight parts. The fixing body supports an outer periphery part of the leaf springs and accommodates therein the movable body such that the magnet, the cores and the spring stopper weight parts are capable of moving upwardly and downwardly inside the coil.
