Abstract
A motor has a rotatably supported rotor shaft and a rotator that rotates together with the rotor shaft. The rotator includes a shaft insertion section that has an internal peripheral surface and a specified length in an axial direction in which the rotor shaft is inserted. The internal peripheral surface has a first internal peripheral surface of a small diameter and a second internal peripheral surface having a diameter slightly greater than that of the first internal peripheral surface. The first internal peripheral surface engages the rotor shaft under a pressure, and the second internal peripheral surface is slightly spaced a distance from the rotor shaft, such that a gap is created between the second internal peripheral surface and the rotor shaft. 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.
