    • An electric power converter can include an electric power converter case mounted on rolling stock, a unit mounting section formed in the electric power converter case and having a cooler insertion opening, and an internal unit mounted on the unit mounting section. The internal unit can include a cooler projecting from the unit mounting section through the cooler insertion opening into an outside air introduction section into which the outside air is introduced and a plurality of securing holders made to butt against the unit mounting section for securing the internal unit. Each of the securing holders can have a butting surface for butting against the unit mounting section to form a step by making the butting surface protrude from the opposed surface of the internal unit facing the unit mounting section.
    • 电力转换器可以包括安装在车辆上的电力转换器壳体,形成在电力转换器壳体中并具有冷却器插入口的单元安装部分和安装在单元安装部分上的内部单元。 内部单元可以包括从单元安装部分经由冷却器插入口突出到外部空气引入部分中的外部空气引入的冷却器和与该单元安装部分对接的多个固定保持器,用于固定内部单元 。 每个固定保持器可以具有用于对接单元安装部分的对接表面,以通过使对接表面从内部单元的面向单元安装部分的相对表面突出而形成台阶。
