The present invention provides a movable water-protection apparatus capable of driving a water barrier plate manually or automatically when needed. The movable water-protection apparatus includes a water barrier plate (2, 50) for shutting out water, such as seawater, river water, and rainwater, likely to intrude into a basement (G) and a driving device for driving the water barrier plate (2, 50) upward from an underground position along a guide device (10) or a side plate (60). The water barrier plate (2, 50) is disposed in an underground space at an entrance of the basement (G). The driving device has a water pressure type piston/cylinder unit (20) to which service water is supplied.
