PROBLEM TO BE SOLVED: To provide a hybrid type stepping motor which enables reduction of vibration and noise.SOLUTION: A hybrid type stepping motor includes: a rear flange 5 in which four corner parts respectively have four protruding parts 5b to 5e extending in an axial direction; and a stator core 10 including four cutout parts 12a for housing the protruding parts 5b to 5e of the rear flange 5. The stator core 10 comprises: a core B12 in which the four cutout parts 12a for housing the protruding parts 5b to 5e of the rear flange 5 are formed; and a core A11 in which the cutout parts are not formed. The four protruding parts 5b to 5e of the rear flange 5 presses the core A11 in the axial direction.SELECTED DRAWING: Figure 3 |
