A brushless winding field rotational electric machine 10 positioned between a starting device 4 and a case 5 enclosing the starting device 4 includes: a stator 3, which is held to the case 5, including an alternating-current coil 14 configured to generate a rotation magnetic field by alternating current; a field core 6, which is held to the case 5, including a field coil 2 to be excited by direct current; and a rotor 1 disposed on an outer periphery of the starting device 4 and rotatably held about a rotational axis 7 thereof relative to the stator 3 and the field coil2 . The rotor 1 includes a connection portion 31 to be connected to a synchronized rotation member 30 configured to rotate in synchronization with an engine 8 along the rotational axis 7, on a facing surface to the synchronized rotation member 30.
