To provide a hermetic housing that makes a screw be hardly loosened.SOLUTION: A power converter includes a hermetic housing comprising: a case 6 comprising an aperture; a closing member 4 for closing the aperture; and a sealing material S1 for sealing a gap between the case 6 and the closing member 4. The case 6 comprises a case side abutting part 6a that is provided around the aperture and receives a screw 9 for fixing the closing member 4. The closing member 4 comprises a closing member side abutting part 4a that abuts on the case side abutting part 6a when closing the aperture. On either one of the case 6 and the closing member 4, the case side abutting part 6a and the closing member side abutting part 4a abut. At a position adjacent to an abutting portion CA1, a storage part 10 for storing the sealing material S1 before curing is provided. The hermetic housing has, at the boundary on the abutting portion side of storage part 10, a flow inhibition surface 10a inhibiting the sealing material S1 before curing from flowing toward the abutting portion, resulting in the sealing material S1 after curing remaining in the storage part 10 and not intruding into the abutting portion CA1.SELECTED DRAWING: Figure 3
【課題】ネジが緩みにくい密閉型筐体を提供する。【解決手段】電力変換器において、開口を備えている筐体6と、開口を塞ぐ閉塞部材4と、筐体6と閉塞部材4の間を封止する封止材S1を備えている。筐体6は、開口の周囲に設けられているとともに閉塞部材4を固定するネジ9を受け入れる筐体側当接部6aを備えている。閉塞部材4は、開口を塞いだときに筐体側当接部6aと当接する閉塞部材側当接部4aを備えている。筐体6と閉塞部材4のどちらか一方には、筐体側当接部6aと閉塞部材側当接部4aが当接する。当接部位CA1に隣接する位置において、硬化前の封止材S1を収容する収容部10が設けられている。密閉型筐体では、収容部10の当接部位側の境界に、硬化前の封止材S1が当接部位に向けて流動することを禁止する流動禁止面10aが形成されており、硬化後の封止材S1が、収容部10内に留まっているとともに当接部位CA1に侵入していない。【選択図】図3
