簡易に得られる。Next, to explain the effect of the present invention, according to the shaft structure of the internal combustion engine of the present invention, the flywheel magnet 8 is attached to the output shaft 4 at the fan mounting shaft 9, the pulley 12,
or 13, the flange portion 17 has a large diameter flange portion 17 of the boss 7 which is based on the inside of the boss 7, and therefore naturally has great rigidity,
Because it is located close to
Despite the presence of the magnet 13, similar to the flyboil magnet 8, there is little whirling vibration and coaxiality with the output shaft 4 can be easily obtained.
したがって、本考案によれば、内燃機関の出力軸４から
