PROBLEM TO BE SOLVED: To provide a levee shaper of a levee-plastering machine, which can simplify constitution associated with attachment and detachment and can easily and quickly perform attachment and detachment operation without requiring a new tool in attachment and detachment of a levee shaping part of an upper surface corresponding to the levee height.SOLUTION: When a levee shaping part 30 of an upper surface is covered with a levee shaping part 40 of a covered upper surface, an inside face of a side 43 of the levee shaping part 40 of the covered upper surface includes an approximately circle-shaped guide member 45 for keeping an interval from a side wall surface 34 of the levee shaping part 30 of the upper surface in the peripheral direction and an interval between the inside face of the side 43 of the levee shaping part 40 of the covered upper surface and the side wall surface 34 of the levee shaping part 30 of the upper surface is kept constant. Here, a top surface 41 of the levee shaping part 40 of the covered upper surface has a hook member 42 for fixing a position relationship between the top surface 41 and a top wall surface 31. When the levee shaping part 40 of the covered upper surface is moved in a state in which the levee shaping part 30 of the upper surface is covered with the levee shaping part of the covered upper surface, a levee-plastering machine is equipped with an engagement edge part 38 to be engaged with the hook member 42 of the levee shaping part 40 of the covered upper surface. |
