To provide a sealing type water container which can reduce the shake amplitude of furniture in case of an earthquake small.

A sealing-type container in which clean water is enclosed, is fixed to the top plate section of the furniture with a suction cup for fixing. In the sealing type water container, when the furniture repeats a tilt in an earthquake, although the clean water within the anchored sealing type water container repeats translocation in a sloping direction, since the period of the tilt of the furniture and the period of the translocation of the clean water do not coincide with each other because the translocation of the clean water is restricted by a water partition plate within the sealing type container, the shake amplitude of the furniture can be suppressed small.
