於て、回転子鉄心に設けた回転軸との恰合孔の寸法精度
をダイカスト前後において変形収止の為、嵌合孔の形状
を円周上に沿って複数個Ｃ凹凸形状とし、かつこの凸部
外周近傍に凸部と又応した数の緩衝孔を設けこの凹部と
緩衝孔でダイカスト型締の側圧による生じる変形を吸収
せしＶたことを特徴とする電動機回転子。In a structure in which the rotor core and rotating shaft of a small electric motor are shrink-fitted, the shape of the fitting hole is adjusted to ensure dimensional accuracy of the fitting hole with the rotating shaft provided in the rotor core to prevent deformation before and after die casting. A plurality of C uneven shapes are formed along the circumference, and a number of buffer holes corresponding to the number of convex parts are provided near the outer periphery of the convex part, and the deformation caused by the lateral pressure of die-casting mold clamping is absorbed by the concave parts and buffer holes. An electric motor rotor characterized by the following characteristics:
