Claims

[Scope of utility model registration request]

In a rotor configured by arranging a plurality of permanent magnet pieces on the outer periphery of a magnetic yoke and fitting a metal tube to the outer periphery of the permanent magnet pieces, a shaft is attached to the adjacent part of the permanent magnet pieces. A rotor characterized in that a gap extending in the direction is provided, and a protrusion projecting into the gap is provided on an inner peripheral portion of the metal tube that abuts the gap.
