Abstract
In a rotor of a motor or the like, in order to suppress scattering of a part of a magnet provided around a rotating shaft, the rotor has a cylindrical magnet through which the rotating shaft passes, a first holder which covers the magnet from one side in an axial direction of the rotating shaft and a second holder which covers the magnet from the other side in the axial direction. The magnet is press-fitted into a first body portion of the first holder and a second body portion of the second holder, and a first end of the first body portion and a second end of the second body portion are joined by welding or the like. An inner diameter of the first end and the inner diameter of the second end are larger than an outer diameter of the magnet.
