PROBLEM TO BE SOLVED: To provide a double spindle multilayer motor capable of enhancing torsional strength and torsional rigidity against a torsional input sharply as compared with a cantilever stator supporting structure while ensuring coupling of an outer rotor securing member and an outer rotor rotary shaft. SOLUTION: In a double spindle multilayer motor M arranged with an outer rotor OR and an inner rotor IR on the inner and outer circumferences while holding a cylindrical stator S between, the stator S couples an outer rotor case 62 for securing the outer rotor OR while supporting for a shaft member having one axial end part secured to a motor case 2 and the other axial end part secured to a motor side cover 1, and a second motor shaft 9 arranged at the central position of motor shaft through a gear mechanism arranged at a space position surrounded by the other axial end part of the stator S and the motor side cover 1.
