PROBLEM TO BE SOLVED: To provide an armature (motor) capable of achieving suppression of magnetic saturation around caulking and fixing portions and suppression malfunction related to winding of coils to teeth by changing a shape of leading end portions of the teeth in association with relative enlargement of the caulking and fixing portions.SOLUTION: When caulking and fixing portions 30 having diameters relatively enlarged are set at substantially T-shaped leading end portions of teeth 24, centers O1 of the caulking and fixing portions 30 are shifted to one sides with respect to circumferential direction center lines L1 of the teeth 24. Further, therefore, concave shapes of corner portions 31 of one sides being directions where the caulking and fixing portions 30 are shifted swell out with respect to concave shapes of other sides in pairs of corner portions 31 and 32 among radial direction portions 25 of the teeth 24 and circumferential direction portions 26 and 27 constituting substantially T-shapes. |
