The cylindrical portion is provided with an overhanging portion for positioning with the rotor shaft, a part of which is extended in the axial direction, and a cylindrical portion for press-fitting the rotor shaft disposed at one end of the overhanging portion, and the cylindrical portion is drawn. A small commutatorless DC motor whose rotor shaft is fixed to the rotor frame by applying (2) Practical application in which the rotor shaft and rotor frame are assembled and fixed by threading the inner side of the cylindrical part created by the above-mentioned drawing process with taps and tightening the rotor shaft, which has a similarly threaded tip. A small commutatorless DC motor as set forth in claim 1 of the patent registration claim.
