Abstract
In insulators of a motor, in an external wall portion, the outer diameter sides of winding drum portions represent winding-drum-portion-side external wall portions, and the outer diameter sides of the opening portions represent opening-portion-side external wall portions; and the winding-drum-portion-side external wall portions have such a thickness in a radial direction that, in the axial direction of a stator, the leading end sides far from the stator are smaller than the base end sides close to the stator, and the thickness of the base end sides of the winding-drum-portion-side external wall portions is greater than the thickness of the opening-portion-side external wall portions.
