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.
