Abstract

A rotational driving force imparting device is equipped with an electric motor device (50) and a planetary gear transmission device (10). Among the sun gear shaft (12), planetary gear carrier shaft (27), and inner gear carrier shaft (37) of the planetary gear transmission device (10), one shaft forms an output shaft (Ao), another one shaft forms a constant speed input shaft (Ac), and the remaining one shaft forms a variable speed input shaft (Av). The electric motor device (50) is equipped with: a constant speed electric motor (51) rotating about a shaft line (Ar) and having a constant speed rotor (52) connected to the constant speed input shaft (Ac); and a variable speed electric motor (71) rotating about the shaft line (Ar) and having a variable speed rotor (72) connected to the variable speed input shaft (Av). A shaft insertion hole (74) formed in a cylindrical shape centered at the shaft line (Ar) and penetrated in a shaft direction is formed in the variable speed rotor (72), and the constant speed rotor (52) is inserted into the shaft insertion hole (74).
