In an electric motor, a rotary shafthas an outer circumferential surfacewith a diameter that decreases from a larger diameter sectionhaving a first diameter toward a smaller diameter sectionhaving a second diameter smaller than the first diameter. A sleeveis mounted by interference fit with an inner circumferential surfacewith a diameter that decrease from a front end adjoining the larger diameter sectiontoward a rear end adjoining the smaller diameter section, to the outer circumferential surfaceof the rotary shaft. With such a construction, the sleeveis fitted with the substantially entire surface of the inner circumferential surfaceto the outer circumferential surfaceof the rotary shaft
