Abstract: An actuator in accordance with an embodiment includes at least one linear motor, a partition member and a fan. The linear motor is configured to linearly move a shaft serving as a movable member. The partition member is provided close to the shaft and configured to partition a space defined between the shaft and a control board for controlling the linear motor. Further, the fan is arranged on the side of the shaft with respect to the partition member and configured to flow an air existing in a partitioned space on the side of the shaft.
