Abstract
A sealing device is provided which is capable of a two-step holding operation with the use of a linear solenoid. The sealing device includes a stopping mechanism for stopping a movement of a movable part that forms the linear solenoid when the linear solenoid is driven at a predetermined midway point between a start point and an end point after the nozzle part has been moved from the waiting position to the stop position, and for releasing the movable part from a stop to allow the movable part to move again and reach the end point after the nozzle part has been returned from the stop position to the waiting position.
