Electric motor and method for manufacturing same

An electric motor, comprising:

• a rotor;
• a stator disposed around the rotor;
• a housing that has a storage space for storing the rotor and the stator, an opening for opening the storage space to one side in an axial direction along a central axis of rotation of the rotor, and a notch that is concaved from an edge surface surrounding the opening toward the other side of the axial direction;
• a lead wire connected to the stator;
• a partition wall that is provided on the inside of the notch of the housing in order to separate a sealing space for injecting a sealant for covering at least a part of the stator and a space outside the sealing space from each other, and has a through-hole for allowing the lead wire to be extended to the outside of the sealing space;
• a cover that can be attached to the housing from the one side in the axial direction;
• and
• an elastic member that is more elastic than the partition wall and overlapped with the partition wall in the axial direction,
• wherein an end surface of the partition wall, or of the elastic member, that is disposed at the one side in the axial direction, is disposed on a plane surface including the edge surface of the housing or on the one side in the axial direction with respect to the plane surface, and
• the cover has a flat contact surface capable of coming into contact with the end surface of the partition wall or the elastic member and with the edge surface of the housing,
• wherein the elastic member is provided at the one side in the axial direction with respect to the partition wall or at another side in the axial direction with respect to the partition wall, wherein the another side is opposite the one side in the axial direction, and wherein when the elastic member is provided at the one side in the axial direction the elastic member separates the partition wall from the cover such that the partition wall does not contact the cover, and when the elastic member is provided at the another side in the axial direction the elastic member separates the partition wall from the housing such that the partition wall does not contact the housing.
