A rotating electrical machine such that positional deviation caused by a part tolerance can be absorbed in an electrical connection between a power conversion device and a rotating electrical machine main body, and size can be reduced without a structure becoming complex, is obtained. The rotating electrical machine is characterized by including a power terminal unit of the rotating electrical machine main body housed in a housing, the power conversion device fixed to the housing, and a multilayer bus bar connected to the power terminal unit of the rotating electrical machine main body as a power terminal of the power conversion device, wherein the multilayer bus bar has flexibility, and is bent by being connected to the power terminal unit.

Rotating electrical machine

Provided is a power conversion device that has improved assembling workability and that realizes downsizing thereof. The power conversion device includes: an electrical component; a casing enclosing the electrical component and terminals connected to the electrical component and an outside, the casing having a plurality of opening portions in which the terminals are disposed; and a casing lid covering the opening portions. A shaft seal provided so as to be in contact with a side surface contiguous with a rim of an opening portion among the opening portions, and a surface seal provided so as to be in contact with a surface contiguous with a rim of an opening portion among the opening portions, are disposed so as to be in contact with the casing lid.

Power conversion device

Provided is a power conversion device, including: a semiconductor module including a semiconductor switching element; a heat sink configured to cool the semiconductor module; a spring member configured to press the semiconductor module onto the heat sink; a casing configured to accommodate the semiconductor module and the spring member; and a bridge-like structure configured to press the semiconductor module onto the heat sink through intermediation of the spring member when the casing is mounted to the heat sink.

Provided is an electric device that includes a connector holder for positioning a connector relative to a control board and fixing a harness. In the electric device, a board-in connector for wire-to-board connection is disposed at an end of a harness for electrical connection, and terminals of the board-in connector are soldered and fixed to terminals in a control board. The electric device includes a connector holder fixed to a housing together with the control board. The connector holder includes a fixation portion for fixing the board-in connector to the connector holder, and a holding portion for holding and fixing the harness.
