AC GENERATOR WITH PUMP

PURPOSE:To prevent an irregular wear due to the one side contact of a spline coupling section and a noise from occurring by disposing a bearing between the other end of a rotational shaft of a pump section and one end of a rotational shaft of a generator section. CONSTITUTION:When power is transmitted to a pulley 16, the first rotational shaft 13 of a pump section 10 rotates, it is transmitted through spline coupling sections 18, 41 to the second rotational shaft 35 of a generator section 30, i.e., a pushing shaft 38 and a rotational shaft section 39 to rotate a rotor 42, thereby generating a current. The shaft 13 is supported at its one end 14 by a first bearing 12 held by the casing 11 of the section 10, and at the other end 17 by a second bearing 45 disposed between the other end 17 of the shaft 13 and the pushing shaft 38 of the shaft 37 of the section 30. Accordingly, the shaft 13 is rotated in high centering accuracy with respect to the shaft 35.
