PROBLEM TO BE SOLVED: To provide a motor which suppresses flux leakage and enables improvement of output characteristics.SOLUTION: In a motor 11, a stator 16 and a rotor 21 are housed in a case 12. The case 12 has: a yoke housing 13 formed into a substantially cup shape; and an end plate 14 which closes a front side opening part of the yoke housing 13. The yoke housing 13 has a structure that a size of a cross section, which is created by cutting the yoke housing 13 in an axial direction, is partially varied by forming groove parts 53b, 54b on at least a bottom part 52.SELECTED DRAWING: Figure 1 |
