To provide a horizontality maintaining device having an excellent feature that makes a base less likely to incline significantly even if a trouble occurs in a mechanism for maintaining horizontality.SOLUTION: A horizontality maintaining device 1 maintains horizontality of a table 10 and includes: the table 10 supported by a base 2 so as to be swingable along a spherical surface Sp; a first driving mechanism 41 which changes inclination of the table 10 in a pitch direction; and a second driving mechanism 42 which changes inclination of the table 10 in a roll direction. In the horizontality maintaining device 1, a swing center C of the table 10 is located at a higher position than a centroid G of the table 10 in a vertical direction.SELECTED DRAWING: Figure 10

    【課題】水平を維持するための機構にトラブルが生じても台が大きく傾くおそれが少ない優れた特性の水平維持装置を提供すること。【解決手段】台10の水平を維持する水平維持装置1は、球面Spに沿って揺動可能なように基台2によって支持された台10と、台10のピッチ方向の傾きを変更する第1の駆動機構41と、台10のロール方向の傾きを変更する第2の駆動機構42と、を備えており、この水平維持装置1では、鉛直方向において、台10の揺動中心Cが台10の重心Gよりも高く位置している。【選択図】図10
