Obtained is a power conversion device that suppresses size increase thereof while improving cooling performance for a smoothing capacitor. The power conversion device includes: a cooler having a cooling surface on an outer side thereof and a flow path on an inner side thereof, the flow path being formed such that a coolant flows through the flow path; and a smoothing capacitor fixed to the cooler, the smoothing capacitor being thermally connected to the cooling surface with a heat transfer member therebetween and configured to smooth DC power. A thickness of the heat transfer member between the smoothing capacitor and a portion, of the cooling surface, to which the smoothing capacitor is thermally connected is set to be smaller than a wall thickness of the cooler between the flow path and the portion, of the cooling surface, to which the smoothing capacitor is thermally connected.

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.

As monitorheld by casingis upwardly pushed, clampis rectilinearly moved toward push latchin cooperation with rotation of the monitor, the monitoris rotatable by claw sectiondisengaged from locking hole, and a striker holding sectionengages with strikerto be forced into the main body of the latchto be in engagement locked position. As the opened monitoris upwardly pushed, the clampis rectilinearly moved toward the latchin cooperation with the rotation of the monitor, the holding sectionplaced in the locked position with the strikeris forced into the main body of the latchto be in engagement-lock releasing position, and the released sectionis urged and moved by springto lock the holeto hold the monitorin closed position.
