ABSTRACT:
An actuator including magnets arranged on a plane on a plane, coils respectively arranged to face the magnets and move relatively with facing the magnets when a current is applied thereto, a moving member connected to either the magnets or coils, a guide member that guides the moving member to move in a given two-dimensional range; and a hit prevention mechanism to prevent the moving member from hitting a movable limit in the given two-dimensional range. The hit prevention mechanism is provided at the movable limit (edge) in the two-dimensional range. It is thus possible to prevent the moving member from hitting the movable limit. This can prevent damage or any hitting sound. The actuator can be used in a comfortable manner and stably for a long period.
