PROBLEM TO BE SOLVED: To provide the levee shaping body of a levee plastering machine which facilitates attachment and detachment, without needing a new tool, and enables a user to perform the attaching and detaching work easily and quickly, in attachment and detachment of a topside levee shaping part corresponding to the level of a levee.SOLUTION: The interval in a circumferential direction between the inner flank of the flank 43 of the topside levee shaping part 40 and the flank face 34 of a mounting board 30 constant, since the inner flank of the flank 43 of the topside levee shaping part 40 is provided with a guide member 45 for keeping the interval to the flank face 34 of the mounting board 30 constant in the circumferential direction, when the topside levee shaping part 40 is put on the mounting board 30. Here, the bottom 84 of the topside levee shaping part 40 is provided with a hook member 42, which extends to the top wall face 31 of the mounting board 30 from the outer flank of the bottom 84 and fixes the positional relation between the bottom 84 and the top wall face 31. Then, the top wall face 31 of the mounting board 30 is given a notch 32 that the hook member 42 gets in, and it is equipped with an engaging rib 38 that the hook member 42 of the topside levee shaping part 40 engages, when it is shifted with the topside levee shaping part 40 put on the mounting board 30. |
