摘要：
A surface magnet type motor having a magnet at a surface of a rotor includes an anti-scattering tube formed in a cylindrical configuration longer in length than the magnet of the rotor in the axial direction, having the magnet press-fitted inside to prevent scattering of the magnet. A stress alleviation portion is provided to alleviate stress generated at an end of the magnet press-fitted into the anti-scattering tube.
