PROBLEM TO BE SOLVED: To provide a slope variation detection device which can keep production costs low with a simple structure, and which can precisely detect slope variations. SOLUTION: In an operating mechanism 2, a detection sphere 23 is placed statically on a rolling plate 22 placed on three spheres 21 placed statically on a placement stand 19 adjusted to the horizontal position with a fine adjusting screw 17. When the placement stand 19 inclines due to the variation of a slope S, the detection sphere 23 falls due to the rolling of the spheres 21, and breaks a detection bar 31 passing through a guide tube 26 from an inclination plate 24. A display plate 35 falls due to the breakage of the detection bar 31, and becomes a display state exposed to the outside of a case 30. COPYRIGHT: (C)2008,JPO&INPIT
