Electric oil pump, housing body portion, and pump cover

An electric oil pump comprising:

• a shaft extending in an axial direction;
• a motor including:
• a rotor that is rotatably fixed to the shaft;
• and
• a stator facing the rotor with a gap in a radial direction;
• a pump driven to pump oil by power of the motor;
• and
• a housing accommodating the motor and the pump;
• wherein the pump includes:
• an inner rotor coupled to the shaft on one side in the axial direction and including external teeth;
• and
• an outer rotor surrounding the inner rotor from an outer side in the radial direction and including internal teeth meshing with the external teeth;
• the housing includes a housing body portion made of resin and a metal housing portion made of metal;
• the housing body portion includes:
• an accommodation recess portion that is recessed from an end portion on one side in the axial direction toward another side in the axial direction and accommodates the pump;
• and
• a stator holding portion that holds the stator;
• the accommodation recess portion includes a recess portion inner circumferential surface surrounding the pump from the outer side in the radial direction;
• the metal housing portion is at least partially embedded in the housing body portion;
• and
• the metal housing portion includes a cylindrical circumferential wall portion between the pump and the recess portion inner circumferential surface in the radial direction.
