PROBLEM TO BE SOLVED: To solve problems that, in a rotor type in which permanent magnets are inserted into through holes provided in a rotor core comprising stacked electrical steel sheets blanked by a die of rotors for electric motors that are fixed between a pair of brackets in such a way as to be freely rotatably via bearings, weight of an adhesive makes the imbalance amount of the rotor itself large, because the adhesive and the like are used to fix the inserted permanent magnets in the thrust and radial directions and that the yield of production deteriorates because the curing time of the adhesive is required. SOLUTION: By providing parts at both sides of the rotor core and by configuring to sandwich the permanent magnets between the two parts, the fixing in the thrust and radial directions is made possible, so that the permanent magnets can be fixed without using materials including the adhesive.
