Provided is a vehicle brushless AC generator capable of improving workability and improving insulation property to enhance reliability while preventing a decrease in slot space factor of a stator coil. In the vehicle brushless AC generator, grooves (20a, 20b) are formed in an inner wall of a front bracket (20), and a mold body (26) for insulating and protecting a lead wire (25) is mounted into the grooves (20a, 20b).
