PROBLEM TO BE SOLVED: To arrange a power generating coil at a portion not degrading cooling performance, while maintaining compactness of a power unit. SOLUTION: A coil support part 21C formed integrally with a crankcase 21 is disposed at a position adjacent to an opening port 21A, from a side end of an opening port 21B to a start part of an air-guiding passage 21A. The coil support part 21C is extended from the crankcase 21 upward of a muffler part 26 of an engine to form an insulating gap between the coil support part and the muffler part 26.
