Abstract: A power conversion device includes a housing, a circuit board coupled to the housing, an electronic component including lead wires, and a heat radiation plate. The heat radiation plate supports a heat radiation face of the electronic component by a first face of the heat radiation plate in a heat exchangeable manner. The heat radiation face is disposed to face the first face. The heat radiation plate includes concave parts provided on a second face of the heat radiation plate in a position of facing the lead wires. The second face intersects with the first face. The concave parts dent toward a third face of the heat radiation plate. The third face is located on an opposite side of the second face. The third face intersects with the first face. The heat radiation plate is coupled to the housing on the third face in the heat exchangeable manner.

Abstract: A power conversion device includes first and second components and pairs of engagement members each including male and female engagement members. The male engagement member includes an insertion part having a substantially flat plate shape. The female engagement member includes first and second clamping parts arranged to be opposed to each other. In each of the pairs of engagement members, the male and female engagement members are respectively arranged on one and another of the first and second components. The first and second components are coupled when the female engagement member clamps the insertion part inserted between the first and second clamping parts in each of the pairs of engagement members. Each of the first and second clamping parts is bent to form a projecting portion toward an opposed surface. A gap is provided at a distal end of each of the first and second clamping parts.
