Abstract

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