PROBLEM TO BE SOLVED: To provide a ridging body for a ridge coating machine in which a ridge can firmly be shaped and scratching traces are hard to remain in the ridge after the shaping and a smooth ridge can be made.SOLUTION: A ridging body includes a rotating body (slope ridging part 82, upper ridging part) rotating mainly on a rotary central axis, and applies soil on an old ridge K by an outer circumferential surface of the rotating body. The rotating body is formed of: curved surface sections 841 where the distance from the rotary central axis gradually decreases toward the opposite side of the rotation direction F and a curved surface 841a is formed in the outer circumferential surface; and edge sections 842 where the distance from the rotary central axis gradually increases toward the opposite side of the rotation direction F and an end face 842a is formed. |
