Abstract:
A motor comprising a rotor shaft and a rotator that rotates together with the rotor shaft, wherein the rotator comprises:a shaft insertion section having a specified length in an axial direction in which the rotor shaft is inserted, the shaft insertion section having an internal peripheral surface, the internal peripheral surface having a first internal peripheral surface of a first diameter and a specified length in the axial direction, and a second internal peripheral surface having a second diameter slightly greater than the first diameter of the first internal peripheral surface such that a gap is created between the second internal peripheral surface and the rotor shaft and having a specified length in the axial direction, and wherein the rotor shaft is pressure-inserted in the first internal peripheral surface to be affixed to the rotator, and an adhesive is filled in the gap between the second internal peripheral surface and the rotor shaft to affix the second internal surface to the rotator, wherein the adhesive is not present between the rotor shaft and the first internal peripheral surface of the shaft insertion section.
