摘要：
The motor of the invention is an outer rotor type motor, and a rotor includes a cylindrical rotor frame that is opened at one end thereof in an axial direction, and a hollow cylindrical magnet attached to an inner periphery of the rotor frame. The magnet has a joining portion joined to an inside cylindrical portion of the rotor frame, and a protruding portion that further protrudes in the axial direction from one end, the outer diameter of the protruding portion is larger than the inner diameter of the rotor frame, and the joining portion is directly brought into close contact with a portion ranging from the one end to at least a portion of the inside cylindrical portion.
