The present invention provides a motor comprising an insert nut (10) which has, in two locations on the surface in the axial direction, a knurled part (101) formed with a protrusion (103) for preventing rotation and withdrawal, and which is is embedded between a motor rotor (3) and a magnet assembly (7), and clamps the motor rotor (3) and magnet assembly (7). A concave part (104) of the insert nut (10) between the knurled parts (101) is positioned at the assembly boundary between the motor rotor (3) and magnet assembly (7). |
