Abstract
A stator includes a stator iron core including a plurality of slots, and bobbins fitted into the slots. Each of the bobbins includes flanges provided at both respective ends of the stator respective flanges. The stator iron core includes projections protruding from inner surfaces of the slots. The bobbins are positioned by engaging the protrusions and the projections to each other.
