A generator/motor includes a ring-shaped stator core (20) fixed to a motor housing (10), and a motor rotor (30). The motor rotor (30) includes a ring-shaped rotor yoke (35) which rotates in cooperation with the crankshaft (1) and which is opposed to an inner peripheral surface of the stator core (20) with a predetermined gap therebetween and a rotor flange (31) which supports and fixes the rotor yoke (35) at its outer peripheral surface. The rotor flange (31) is rotatably supported by a support member (51 a) of the motor housing (10) through a bearing (60). A flywheel (100) is fixed to the crankshaft (1) and a cylindrical shaft portion (40) is interposed between the crankshaft (1) and the motor rotor (30). The cylindrical shaft portion (40) is spline coupled to an inner tooth spline formed on the flywheel (100). The precision of an air gap can be secured between the stator core and the motor rotor with a simple structure.; Even if the crankshaft receives vibration of an engine and its core vibration, the vibration of the core can be attenuated through the cylindrical shaft portion, the rotation precision of the motor rotor is maintained for a long time, and the air gap between the stator core is maintained constant for a long term. As a result, an engine with a generator/motor as an auxiliary power unit, which is a hybrid engine capable of obtaining desired motor efficiency and the power generating efficiency, can be obtained.
