摘要： A vibration actuator has a movable body and a fixing body. The movable body includes: a disk-shaped magnet; annular cores each having an opening at a center thereof; and spring stopper weight parts, and stacked such that the magnet is disposed at a center of the movable body, the annular cores is fixed on front and rear surfaces of the magnet in its axial direction, and the spring stopper weight parts are joined with the annular cores at the opening. Each spring stopper weight part includes: a spring fixing part connecting to one of the elastic support parts; a joining protrusion part inserted into the opening of one of the annular cores; and a weight body part provided between the spring fixing part and the joining protrusion part, having a larger diameter, and disposed to face and join with an annular surface of one of the annular cores.

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.

摘要： A vibration actuator includes a movable body provided with one of a coil and a magnet that is disposed radially inward of the coil with a gap formed therebetween, a fixing body provided with the other of the coil and the magnet and a shaft portion, and an elastic support portion, the movable body vibrating in a vibration direction by means of cooperation between the coil supplied with power and the magnet. The movable body is provided with a through-hole into which the shaft portion is inserted with a gap formed between the through-hole and an outer peripheral surface of the shaft portion and the elastic support portion supports the movable body such that the movable body does not come into contact with the shaft portion at a time when the movable body does not vibrate and at a time when the movable body vibrates.
