PROBLEM TO BE SOLVED: To accurately maintain parallelism of an upper face of an upper side support base and a lower face of a lower side support base without separately providing a guide mechanism of a movable body in a leveling device of a structure movably interposing the movable body of a wedge shape between the upper side support base and the lower side support base. SOLUTION: The upper side support base 12, the wedge shape movable body 16, and the lower side support base 14 are arranged to be stacked, both side parts of a spindle support 20 are fitted in recesses 24, 34 formed on both side walls of recess grooves 22, 32 provided respectively on the support bases 12, 14, a spindle 18 screwed to the movable body 16 is rotatably supported by the spindle support 20, and thus the leveling device 10 is constituted.
