    Abstract: A linear actuator includes a movable element, a stationary element provided with a case in which the movable element is housed, and a magnetic drive mechanism that drives the movable element in a direction of an axis line. In the case, there is provided a sounding hole in a bottom plate part, at the other side in the direction of the axis line; the sounding hole being for discharging a pressure change in accordance with a vibration of the movable element in the direction of the axis line, as an audible level sound. Therefore, at a time when the movable element is vibrated in the direction of the axis line by the magnetic drive mechanism, the vibration is transferred to a user. Accordingly, information can be transferred by way of the vibration. Moreover, the information can also be transferred by way of the sound.
