| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a rotor which can facilitate manufacturing.SOLUTION: The rotor includes: a rotary shaft 51 having a knurled portion 51a at an intermediate portion in the longitudinal direction; and a rotor core 52 externally fitted and fixed to the knurled portion 51a. The lengths of non-knurled portions 51b, 51c on which the knurled portions 51a are not formed on the opposite end sides of the rotary shaft 51 are different from each other, and the grooves 51d, 51e having different shapes are provided on one axial end surface and the other axial end surface.SELECTED DRAWING: Figure 1
【課題】製造を容易とすることができるロータを提供すること。【解決手段】ロータは、長手方向の中間部にローレット部５１ａを有する回転軸５１と、ローレット部５１ａに外嵌固定されたロータコア５２とを備える。回転軸５１は、その両端側のローレット部５１ａが形成されていない非ローレット部５１ｂ，５１ｃ同士の長さが異なり、軸方向一端面と軸方向他端面とに異なる形状の溝部５１ｄ，５１ｅが設けられる。【選択図】図１ |
