PURPOSE:To remove the effect of lateral acceleration and keep an oscillation body such as a ship horizontal by supporting a stable stand on a post that is erected on the deck of the oscillation body through a rotating shaft, providing gears at the end of each rotating shaft, and mounting a heavy weight through gears that are engaged with the upper and lower parts of the gears. CONSTITUTION:A stable stand 15 is supported through rotating shafts 14 and 16 that are intersected mutually at a post 11 erected on a deck 12. Gears 12 and 27 are mounted at the end of each of rotating shafts 14 and 16. Gears 29, 20, 33, and 36 are mounted vertically by engaging with each of the gears 19, 20, 29, and 30 and heavy weights 23, 26, 33, and 36 are mounted on each of the gears 19, 20, 29, and 30 through posts 21, 24, 31, and 34. Since each heavy weight is always located perpendicularly correspond to the oscillation of the deck surface 12, the stable stand 15 is supported horizontally. In this case, especially by arranging the heavy weight at the vertical position, the effect of moment resulting from lateral acceleration can be removed.
