ROTOR FOR INNER ROTOR TYPE MOTOR

To provide a rotor for an inner rotor type motor capable of attaining reduction in cost and reduction in weight and also reducing man-hours for assembly.SOLUTION: The present invention relates to a rotor for an inner rotor type motor comprising: a disc part which is supported so as to be rotatable around a predetermined shaft center; an eccentric part which is provided in the disc part and made eccentric with respect to the shaft center; a peripheral wall part extending from an outer edge of the disc part; and a permanent magnet which is held by the peripheral wall part. In the disc part, a hole is formed radially outside of the eccentric part, and the peripheral wall part includes a protrusion which protrudes radially insides, at an opposite side of the hole while interposing the eccentric part therebetween.SELECTED DRAWING: Figure 1 【課題】低コスト化、軽量化を図ることができ、組み付け工数も削減されるインナーロータ型モータのロータを提供することを課題とする。【解決手段】所定の軸心周りに回転可能に支持された円板部と、前記円板部に設けられ、前記軸心に対して偏心した偏心部と、前記円板部の外縁から延在した周壁部と、前記周壁部に保持された永久磁石と、を備え、前記円板部は、前記偏心部よりも径方向外側に孔部が形成されており、前記周壁部は、前記偏心部を介して前記孔部とは反対側に、前記径方向の内側に突出した突出部を有している、インナーロータ型モータのロータ。【選択図】図１
