A generator/motor mounted on an engine, comprising a ring-shaped stator core (20) fixedly fitted to a motor housing (10) and a motor rotor (30) rotated in association with a crankshaft (1) and having a ring-shaped rotor yoke (35) installed to face the inner peripheral surface of the stator core (20) through a prescribed distance and a rotor flange (31) fixedly supporting the rotor yoke (35) on its outer peripheral surface. The rotor flange (31) is rotatably supported on the support member (51a) of the motor housing (10) through a bearing (60). A cylindrical shaft part (40) is interposed between the crankshaft (1) and the motor rotor (30), and the crankshaft (1) is spline-connected to the cylindrical shaft part (40). An air gap accuracy between the stator core and the motor rotor can be secured by a simple structure and the rotating accuracy of the motor rotor can be maintained long since the effect of the runout of the crankshaft can be attenuated through the cylindrical shaft part even if the crankshaft is run out by receiving the vibration of an engine part. Accordingly, the air gap between the stator core and the rotor motor can be kept constant over a long period. As a result, the generator/motor of the hybrid engine capable of providing specified motor efficiency and power generating efficiency can be provided.
