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.
