A tooth groove is provided at a border portion between a tooth body portion and a protrusion. The angle between a tooth body portion lateral face which is a lateral face in the circumferential direction of the tooth body portion and a tooth body portion stop portion which is a face, of the tooth groove, continued from the tooth body portion lateral face is the right angle or an acute angle. The protrusion is rotated toward the outer side in the circumferential direction, to bring a protrusion stop portion into close contact with the tooth body portion stop portion, the protrusion stop portion being an outer-circumferential-side lateral face of the protrusion, thereby forming a shoe in a tooth.

Method for manufacturing strator, method for manufacturing rotary electric machine, and iron-core block

The rotor includes: a rotor core having a plurality of insertion holes penetrating in an axial direction at intervals in a circumferential direction; and magnets respectively provided in the insertion holes. A space is formed between a hole inner side peripheral surface of each insertion hole and a magnet inner side peripheral surface of each magnet. An adhesion layer portion is formed between a hole outer side peripheral surface of each insertion hole and a magnet outer side peripheral surface of each magnet, and the hole outer side peripheral surface of each insertion hole and the magnet outer side peripheral surface of each magnet with which the adhesion layer portion contacts are formed in a flat-surface shape. A width in a radial direction of the space is longer than a width in the radial direction of the adhesion layer portion.
