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
• each of the elastic vibration dampers is disposed in the mounting leg without adhering to the sleeve and the annular plate,
• the annular plate has an elongated protrusion protruding toward the mounting leg, the elongated protrusion spaced from the collar with a predetermined clearance formed radially outside the collar, and
• a deformation limit of the collar is defined by the elongated protrusion being in contact with the collar during vibration of the housing, wherein
• the elongated protrusion has an end surface at a distal end of the elongated protrusion in a protruding direction from the annular plate toward the mounting leg, and
• the end surface of the elongated protrusion is spaced from each of the end surfaces of the mounting leg in a state in which the elongated protrusion is in contact with the collar.
