[Problem] The purpose of the present invention is to provide a reinforcement structure for an electrically driven compressor, which is configured so that, when a mounting leg is formed on the outer surface of a cover for an inverter housing, the outer surface being located on the extreme axial end side of the electrically driven compressor, the space within the inverter housing is not crushed even when a large force is applied to the electrically driven compressor due to collision, etc., at the front of a vehicle. [Solution] A housing 6 for an electrically driven compressor 1 has an inverter housing 9 comprising a side wall section 91 and a partition wall 92 and accommodating an inverter device 5. The inverter housing 9 is closed at the front of the electrically driven compressor 1 by a cover 10 on which a mounting leg 103 is formed. A hollow protrusion 104 protruding in a dome shape so as to be centered on the mounting leg 103 is provided on the outer surface of the cover 10 to dissipate a load applied from the front of the electrically driven compressor 1 and prevent the space within the inverter housing 9 from being crushed.
