Claims

[Scope of utility model registration request]

A fan wheel that also serves as a magneto wheel is mounted on the end of the crankshaft that protrudes from the crankcase, and
In a forced air-cooled engine configured by connecting a fan case to the outside of the crankcase that can cover the fan wheel and guide exhaust air toward the cylinder side, the fan case has a core that is connected to the outer periphery of the fan wheel. The coil of the outer coil type magneto ignition device is installed with a small gap between the two parts, and the coil of the outer coil type magneto ignition device is installed and connected together. Both dowel pins are integrally provided in the same direction as the crankshaft from two positions on both sides of the center line of the coil, which is perpendicular to the center line of the coil, and both dowel pins are fitted together. 2 of the other part
A positioning structure for a fan case, characterized in that a round hole is formed on one side and a long hole is formed on the other side in a horizontal direction orthogonal to the center line of the coil.
