Abstract
An actuator includes a first damper member and a second damper member that couple a movable body and an immovable body and each include a gel member in a tubular form. The gel member has a first end face and a second end face that are different from each other in cross-sectional shape. The first damper member and the second damper member are oppositely oriented in the axial direction, and are opposite from each other in position of the first end face and the second end face. Consequently, the characteristic variance due to the difference in the direction, in which the movable body moves, is reduced or removed in the actuator as a whole, even if each single damper member is involved with such characteristic variance.
