PROBLEM TO BE SOLVED: To provide a reservoir device, capable of preventing the collapse of a principle of a siphon, even when an upper side weir plate or a lower side weir plate is mounted in a shape which is inclined slightly in the circumferential direction at an axis of connecting piping as the center, holding a reservoir in a full water state, obtaining an original performance and contributing to an improvement in the accuracy of the measured value of the level of a drum for steam-water separating. SOLUTION: The upper side weir plate 6 is formed into a shape, in which a reverse V-shaped cutout 6a is formed at a lower part of a disc. The lower side weir plate 7 is formed in a shape, in which a V-shaped cutout 7a is formed at an upper part of the disc. Then, an area in which the weir plate 6 and the weir plate 7 are overlapped is enlarged circumferentially in the connecting piping 4.
