Abstract
A rotor of a motor includes a cylindrical rotor shaft that is formed through plastic working. The shaft includes a positioning portion that is formed in an inner peripheral surface of the cylindrical shaft by the plastic working of the shaft. The positioning portion is detachably engageable with a securing member, which is insertable into the shaft in an axial direction of the shaft to position the shaft in a circumferential direction. When the positioning portion is engaged with the securing member, relative rotation between the shaft and the securing member is limited.
