PURPOSE:To enhance the wear resistance of a slide structure without loosing an electric conduction between an electric machine coil and a winding slot by providing a conductive mold releasing member on the outer surface of the coil in the slot. CONSTITUTION:Conductive mold releasing members 5-9 and electric machine coils 3, 4 are mounted in the winding slot 2 of a core 1, and rigidly retained by a wedge 10. Charging current from the coils 3, 4 flows to the members 5-9 being in contact with the outer surfaces of all the coils 3, 4, and further flows to the slot, thereby obtaining the routes of the currents on the whole surfaces of the coils 3, 4. Even if an electromagnetic force or a centrifugal force is applied to the coils 3, 4 and the coils are thermally elongated, since the frictional coefficients of the members 5-9 are small, it does not restrict the axial movements of the coils 3, 4.
