In a rotor (100) for a vehicular alternating current generator, a field coil (4) is wound around an insulating bobbin (5). A flange (52) of the bobbin (5) is formed with the first hook portion (53), a second hook portion (54) and a third hook portion (55). A coil winding finishing end (200) is wound around the first hook portion (53) and is opposed to a winding direction of the field coil (4). The finishing end (200) is then directed in a radially inward direction with the second hook portion (54), and extended further in the radially inward direction along the axial end surface of the flange (52). Then, the finishing end (200) is directed in the axial direction with the third hook portion (55) at a position radially inside of the outer peripheral end of the field coil (4). The finishing end (200) forms an angle with itself of less than 90 degrees around the first hook portion (53) when being viewed along an axial direction of the first hook portion (53). <IMAGE> |
