PROBLEM TO BE SOLVED: To provide a rotor of an electric motor which is easily assembled and inhibits a magnet from protruding.SOLUTION: A rotor 10 of an electric motor includes: a rotor core 20 forming a cylindrical shape and in which a housing recessed part 21 is formed on an outer peripheral surface; and an insertion member 50 having a magnet 40 and a case 30 enclosing the magnet 40, the insertion member 50 inserted into the housing recessed part 21. A support protruding part 23 which rotatably supports the insertion member 50 at the interior and the exterior of the housing recessed part 21 is formed on an inner side surface of the housing recessed part 21. Further, the support protruding part 23 restrains the insertion member 50 from being displaced to the outer side along a radial direction in a state where the insertion member 50 is housed in the housing recessed part 21.SELECTED DRAWING: Figure 4 |
