PROBLEM TO BE SOLVED: To prevent a loss from being increased with fastening while surely fastening split cores which are split in a circumferential direction, in a fastening structure of stator split cores.SOLUTION: Each of a plurality of split cores which are split in the circumferential direction, constituting a stator core includes a fastening part which is provided in an end at one side in the circumferential direction and protrudes radially outside for fitting and fixing a stator to a case. An end face of each split core at one side in the circumferential direction includes a first rugged portion that interferes with a one-side split core which is neighboring to the split core at one side in the circumferential direction, when the one-side split core is oscillated around the fastening part after the split core is assembled with the one-side split core. An end face of each split core at another side in the circumferential direction includes a second rugged portion that interferes with another-side split core that is neighboring to the split core at another side in the circumferential direction, when the split core is oscillated around the fastening part after the split core is assembled with the other-side split core. |
