PROBLEM TO BE SOLVED: To provide a levee shaping body of a levee plastering machine that allows an easy and prompt attachment/detachment work in connecting a plurality of top levee shaping parts corresponding to a levee width in a simplified structure without necessity of a new tool.SOLUTION: A hook member 42 is provided in a bottom surface 84 of an extended top levee shaping part 40 to extend to a top wall surface 31 of a top levee shaping part 30 and positionally fix the bottom surface 84 and the top wall surface 31 with each other. Then, a notch 32 is arranged in the top wall surface 31 of the top levee shaping part 30 so as to allow entry of the hook member 42 of the extended top levee shaping part 40 in a state that the extended top levee shaping part 40 is fitted into a tip end part of the top levee shaping part 30. An engaging edge part 38 is also provided in the top wall surface 31 of the top levee shaping part 30 so as to allow engagement of the hook member 42 of the extended top levee shaping part 40 when the extended top levee shaping part 40 that is fitted into the top levee shaping part 30 is operated to rotate. Therefore, the extended top levee shaping part 40 can be easily and promptly connected to the top levee shaping part 30. |
