Abstract

PURPOSE:To enhance the workability of replacing rotary shaft without a jig and to prevent the damage of coil insulation by arranging the openings of one supporting member holding a core at the parts extended from ventilating holes provided on said core, and forming screw holes in the other supporting member. CONSTITUTION:A coil 7 is provided at the outer periphery of the core 1. A plurality of ventilating holes 8 which are pierced in the axial direction are provided on the same circumference of the inside. Openings 9 and 10 which are communicated with said ventilating holes 8 are formed in a pushing plate 3 of the core 1 and commutator drum 5. The opening 9 of the pushing plate 3, which is communicated with one end of the ventilating hole 8, is located at the part extended from the ventilating hole 8. The opening 10 in the commutator drum, which is communicated to the other end of the ventilating hole 8, comprises a ring shaped opening 10a and an opening 10b, which is communicated with said opening 10a, and pierced in the axial direction. Said opening 10b is located at the position which is deviated from the extended line from the ventilating hole 8. A plurality of screw holes 16 are formed at the part of the inner wall of the opening 10a, which are located on the line extended from the ventilating hole 8, so that they are arranged on the same circumference. The screw holes 16, the ventilating holes 8, and the opening 9 provided on the pushing plate 3 are arranged on the same straight line.
