PROBLEM TO BE SOLVED: To provide a levee shaping body or a levee plastering machine capable of more easily performing replacement work of blades without increasing the number of part items and complicating its structure.SOLUTION: A levee shaping body includes a cylindrical member 51, and a plurality of blades 61. The blades 61 each comprise: a first pawl portion 63 capable of at least regulating movement of the blade 61 to a shaft tip direction with respect to the cylindrical member 51, while being engaged with a first slit portion 53 formed on the cylindrical member 51 a second pawl portion 64 capable of at least regulating movement of the blade 61 to the shaft tip direction with respect to the cylindrical member 51, while being engaged with a second slit portion 54 formed on the cylindrical member 51 and a lock portion 65 capable of at least regulating movement of the blade 61 to a direction opposite to the shaft tip direction with respect to the cylindrical member 51, while being engaged with a lock slit portion 55 formed on the cylindrical member 51. The blade 61 is fixed to the cylindrical member 51 by allowing the first pawl portion 63, the second pawl portion 64, and the lock portion 65 to be engaged with the first slit portion 53, the second slit portion 54, and the lock slit portion 55, respectively.
