Claims

[Scope of utility model registration request]

In a so-called engine generator in which one end of the rotor shaft is driven by the engine via a shaft coupling,
between a joint retaining flange fixed to the rotor shaft of the generator and an intermediate flange fixed to the flywheel of the engine; The shaft joint is constructed by joining the joint holding flange and the intermediate flange with a suitable joint such that a gap exists, and the shaft end of the rotor shaft is connected through a guide bearing and the shaft end is The intermediate flange is supported by a shaft end support portion formed at a rotation center portion of the intermediate flange such that a gap at least equal to the gap exists between the root and the end face of the guide bearing. engine generator.
