PROBLEM TO BE SOLVED: To provide a motor to suppress performance deterioration while the motor is reduced in size. SOLUTION: Tip faces of teeth 24 are enlarged along an axial direction of a rotation axis 30 and they are formed by inclining them against the rotation axis 30. Magnets 42 are inclined against the rotation axis 30 so as to face the tip faces inclined against the rotation axis 30. Faces of flange parts 24c of the teeth 24 and the magnets 42 are inclined against the rotary axis 30. Thus, the area of the tip faces of the teeth 24 facing the magnets 42 is secured even if an outer diameter is reduced in the axial direction of the rotation axis 30. Winding 25 is wound so as not to project with respect to the inclined tip faces of the teeth 24 in the axial direction of the rotation axis 30, so that the length of the axial direction of a coil end of the winding 25 is shortened.
