1. An electrical device comprising:
- a drive circuit of an inverter including two or more electrical components, the two or more electrical components including at least two of a circuit board, a capacitor, a bus bar, and a coil;
an inverter case for the inverter that supports the two or more electrical components and is fixed to the two or more electrical components;
a position-adjustment structure that adjusts positions of the two or more electrical components relative to the inverter case with the two or more electrical components being united together, before the inverter case is fixed to the two or more electrical components, the position-adjustment structure including a recess in the inverter case and a deformation member, the deformation member including at least one of a potting material and grease interposed between one of the two or more electrical components and the inverter case and being capable of deforming; and
an intermediate member that is united with the two or more electrical components and electrically connected with the two or more electrical components, the intermediate member including a bus bar;
wherein;
the position-adjustment structure adjusts positions of the two or more electrical components relative to the inverter case by deformation of the deformation member, with the one of the electrical components and the inverter case being in a non-contact state by using the deformation member;
the one of the two or more electrical components is electrically connected with the intermediate member by an electrical connection terminal;
the one of the electrical components and the intermediate member are mechanically connected together with a fixing member, to minimize stress application on the electrical connection terminal from the one of the electrical components or the intermediate member; and
a distance between the intermediate member and the electrical connection terminal is made constant by the fixing member.
