PROBLEM TO BE SOLVED: To provide a power converter that achieves improvement in vibration resistance by suppressing slippage and displacement or the like of a contact plate and allows an arrangement of the contact plate into a case to be highly accurately executed.SOLUTION: The power converter 1 is composed by storing a semiconductor laminated unit 4 in a case 5. The semiconductor laminated unit 4 is formed by laminating each semiconductor module 2 and each cooling pipe 31 and is arranged with a pressurizing member 6 for pressurizing the semiconductor laminated unit 4. The pressurizing member 6 comprises a contact plate 61 in contact with the semiconductor laminated unit 4 and a spring member 62 for pressing the contact plate 61 toward the semiconductor laminated unit 4. The contact plate 61 is provided with each engaging part 60 engaged with each part 50 to be engaged provided in the case 5. Positioning in a direction orthogonal to the lamination direction X is executed by the engagement between each engaging part 60 of the contact plate 61 and each part 50 to be engaged of the case 5 without restricting movement of the contact plate 61 in the lamination direction X. |
