Summary:PROBLEM TO BE SOLVED: To facilitate the assembly of the rotor of an outer rotor motor, and to determine the attachment position of a magnet with high accuracy.SOLUTION: A rotor for motor includes a magnet holder 200 having annular portions 201, 202 separated in the axial direction, and a plurality of struts 203 connecting the two annular portions, and a plurality of magnets 100 attached to the magnet holder 200. Each magnet 100 is held in a space formed by the annular portions 201, 202 and two struts adjacent in the circumferential direction of the struts 203. The annular portion 201 is provided with a notch 201b for attaching the flange and the magnet 100 to the magnet holder 200 by sliding them in the axial direction. 【課題】アウターロータ型モータのロータにおいて、ロータの組み立てが容易であり、且つ、高い精度でマグネットの取り付け位置を決めることができる。【解決手段】軸方向で離間した円環部２０１，２０２、この２つの円環部を繋ぐ複数の支柱２０３を有したマグネットホルダ２００と、マグネットホルダ２００に取り付けられた複数のマグネット１００とを備え、マグネット１００のそれぞれは、円環部２０１，２０２と支柱２０３の周方向で隣接する２つの支柱により形成される空間に保持されており、円環部２０１には、鍔部とマグネット１００を軸方向にスライドさせてマグネットホルダ２００に装着するための切り欠き部２０１ｂが設けられている。【選択図】図１
