Stator and rotary electric machine

A stator for a rotary electric machine provided on an outer periphery of a rotor, comprising:

• teeth arranged in a circumferential direction around an axis;
• slots formed between each pair of the adjacent teeth and each having an accommodation space for coils wound around each tooth;
• and
• a wedge inserted into each of opening portions of the slots that open radially inward;
• a seal member provided radially outward from the wedge in each of the slots and contacting the side surfaces of the paired teeth;
• and
• a reinforcement portion supported by the seal member and facing the accommodation space for the coils;
• wherein
• the wedge is formed in a plate shape capable of bending to reduce a width of the wedge in the circumferential direction,
• the paired teeth include side surfaces facing each other,
• the side surfaces have engagement portions that engage with both end portions of the wedge in the circumferential direction and restrict radially inward movement of the wedge, and
• the reinforcement portion has at least one groove formed therein that opens toward the accommodation space for the coils and extends in a direction parallel to the axis.
