An axial gap type motor generator capable of suppressing the inclination of a rotor resulting from the absence of teeth, wherein a plane (S) having first and second points (P1) and (P2) on the surfaces of the first and second teeth (61a1) and (61a2) opposed to magnets which are positioned on both sides of the cutout part (TW) of the plurality of teeth (61) and a third point (P3) on the surface of the third tooth (61a3) opposed to a magnet which is positioned on the opposite side of a center point (CP) between the first and second teeth (61a1) and (61a2) through a bearing center axis (BO) and nearest a plane (H) including the center point (CP) and the bearing center axis (BO) is inclined relative to a vertical direction to the bearing center axis (BO).
