By providing an engaging part with the stator core on the surface of the wedge, and hooking this engaging part, such as a protrusion or notch, onto both end faces of the stator core, it is possible to prevent the wedge from shifting in the axial direction with simple machining. This has the effect of preventing the flow of cooling air to the area from being obstructed.
