A leveling assembly for setting a vertical prop comprised of inclined surface setting member 20 and horizontal surface forming member 30 wherein; the horizontal surface forming member 30 has a horizontal surface 32 to be adjusted as being horizontal and a first adjusting surface 31 formed by surface not parallel to horizontal surface 32, the inclined surface setting member 20 has a setting surface 21 facing a slope inclined surface 11 and a second adjusting surface 22 facing the first adjusting surface 31 formed by a surface not parallel to setting surface 21, and, the horizontal surface forming member 30 and inclined surface setting member 20 to be piled up to make the first adjusting surface 31 and the second adjusting surface 21 next to each other, and, the horizontal surface 32 to be horizontal to the slope inclined surface 11 by rotating relatively the position and changing degree between the horizontal surface 32 and the setting surface 21.
