Zusammenfassung:	To provide a technology which can inhibit ingress of water into a case.SOLUTION: An electric power conversion unit disclosed by the specification includes: an electric power conversion circuit; a case which houses the electric power conversion circuit and has an opening on an upper surface; bolts each having a head part fixed to the upper surface of the case and a screw part extending upward from the head part; a cover which is fixed to the upper surface of the case by the bolt and covers the opening; and an annular seal member which is disposed so as to enclose the opening between the case and the cover. At a peripheral edge of the opening of the case, a protruding part protruding upward is provided over its entire periphery.SELECTED DRAWING: Figure 2 【課題】ケースの内部への水の侵入を抑制し得る技術を提供する。【解決手段】本明細書が開示する電力変換ユニットは、電力変換回路と、電力変換回路を収容するとともに、上面に開口を有するケースと、ケースの上面に固定されたヘッド部及びヘッド部から上方へ延びるねじ部を有するボルトと、ボルトによってケースの上面に固定されており、開口を覆うカバーと、ケースとカバーとの間において開口を取り囲むように配置された環状のシール部材と、を備える。ケースの開口の周縁には、上方に向けて突出する突出部が、その全周に亘って設けられている。【選択図】図２
