PROBLEM TO BE SOLVED: To restrain increase in the number of parts, and occurrence of crank hammering by avoiding increases in the size and weight of the whole engine, thus restraining vibration of a crank shaft, in an engine where a rotor forming a generator in cooperation with a stator is coaxially fixed on one end of the crank shaft and the crank shaft is rotatably supported on the crank case with bearings intervened in a space to the inner face of a supporting hole formed on the crank case. SOLUTION: The stator 30 is fixed on the crank case 6 side, being offset from an axial center C1 of each of the supporting holes 15, 16 so that magnetic force between the stator 30 and a rotor 31 may be uneven at a part along its peripheral direction.
