A vehicle AC power generator comprising: a rotor that is fixed on a rotation axle pivotably supported by a housing and is disposed in the housing ; a stator that has a stator iron core and a stator winding wound around the stator iron core and is supported by the housing in such a way as to surround the rotor ; a rectifier that is disposed at the outside of one axle-direction side of the housing , that is fixed to the housing , and that rectifies AC electromotive force generated across the stator winding ; a voltage adjuster that is disposed at the outside of one axle-direction side of the housing , that is fixed to the housing , and that adjusts the voltage value of the AC electromotive force to a specified value; and a resin-made protection cover that is produced in the shape of a bottomed tube having a bottom portion and a tubular circumferential wall portion and that is mounted on the housing in such a way as to cover the rectifier and the voltage adjuster , wherein there are provided an attachment member that penetrates a through-hole formed in the bottom portion of the protection cover and is fixed to a portion at one axle-direction side of the housing , an output terminal that extends from the rectifier toward the outside of one axle-direction side of the protection cover , and an insert coated conductor that is supported by the output terminal and the attachment member , that is provided on the rear surface of the protection cover , and that is formed as a member separated from the protection cover and outside of the bottom portion of the protection cover . a rotor that is fixed on a rotation axle pivotably supported by a housing and is disposed in the housing ; a stator that has a stator iron core and a stator winding wound around the stator iron core and is supported by the housing in such a way as to surround the rotor ; a rectifier that is disposed at the outside of one axle-direction side of the housing , that is fixed to the housing , and that rectifies AC electromotive force generated across the stator winding ; a voltage adjuster that is disposed at the outside of one axle-direction side of the housing , that is fixed to the housing , and that adjusts the voltage value of the AC electromotive force to a specified value; and a resin-made protection cover that is produced in the shape of a bottomed tube having a bottom portion and a tubular circumferential wall portion and that is mounted on the housing in such a way as to cover the rectifier and the voltage adjuster , wherein there are provided an attachment member that penetrates a through-hole formed in the bottom portion of the protection cover and is fixed to a portion at one axle-direction side of the housing , an output terminal that extends from the rectifier toward the outside of one axle-direction side of the protection cover , and an insert coated conductor that is supported by the output terminal and the attachment member , that is provided on the rear surface of the protection cover , and that is formed as a member separated from the protection cover and outside of the bottom portion of the protection cover . an attachment member that penetrates a through-hole formed in the bottom portion of the protection cover and is fixed to a portion at one axle-direction side of the housing , an output terminal that extends from the rectifier toward the outside of one axle-direction side of the protection cover , and an insert coated conductor that is supported by the output terminal and the attachment member , that is provided on the rear surface of the protection cover , and that is formed as a member separated from the protection cover and outside of the bottom portion of the protection cover . <EOS>
