Note that the configurations of the stator and rotor are the same as the conventional configuration, and their explanation will be omitted. In the figure, reference numeral 13 denotes a synthetic resin wedge that is inserted and fixed into the slot 12. At one end of the wedge 13, there is a blocker that abuts each side end surface of the inner diameter of the adjacent stator winding frame 3 and closes the opening of the slot 12. 14, and a protrusion 17 which is provided near the closing part 14 at the rear end in the direction of insertion into the slot 12 and abuts against the inner diameter wall 3A of the stator winding frame 3 and the winding 4 to restrict the position of the wedge 13 in the slot 12.
and an outer diameter wall 3 of the stator winding frame 3 at the other end.
This wedge 1 comes into contact with B and together with the protrusion 17.
