Vehicle electric fluid machine

A vehicle electric fluid machine comprising:

• a housing that accommodates an electric motor and has a mounting leg, the mounting leg having an insertion hole extending through end surfaces of the mounting leg in an axial direction of the mounting leg;
• a fastener that has a shaft portion inserted into the insertion hole and a head portion at one end of the shaft portion, the fastener fastening the other end of the shaft portion to a mounting object so that the mounting leg is mounted to the mounting object;
• a sleeve that is disposed between the mounting leg and the shaft portion and that receives a fastening force from the head portion;
• elastic vibration dampers disposed on opposite sides of the mounting leg in the axial direction of the mounting leg, each of the elastic vibration dampers having a cylindrical portion disposed between an inner circumferential surface of the mounting leg and an outer circumferential surface of the sleeve, and a collar extending from one of opposite ends of the cylindrical portion in a radial outward direction of the cylindrical portion;
• and
• an annular plate through which the fastening force received by the sleeve is applied to the mounting leg through the collar, wherein the collar and the cylindrical portion are monolithically formed, wherein the annular plate and the sleeve are monolithically formed, wherein
• each of the elastic vibration dampers is disposed in contact with the mounting leg and in non-adhering contact with the sleeve and the annular plate, and
• the annular plate has a protrusion or a recess on a contact surface of the annular plate being in contact with the collar, the protrusion or the recess is located radially inside an outer circumferential surface of the collar and located radially outside an outer circumferential surface of the cylindrical portion, the protrusion or the recess reducing elastic deformation of the collar in a radial outward direction of the collar.
