PROBLEM TO BE SOLVED : To provide a rotor of a driving motor, reducing leakage of magnetic flux and facilitating setting parts in resin molding.
SOLUTION : The rotor of a driving motor has a structure in which in order to reduce leakage of magnetic flux of a rare-earth permanent magnet, a rotor core is completely separated from a magnetic pole core piece, a stopper of a rare-earth permanent magnet is provided on one portion or each of two portions in an axial direction of the magnetic pole core and the both are formed in sections, and thus, the number of incorporated parts are halved in resin molding to facilitate setting the parts in resin molding.
