Abstract
This power conversion device includes cast resin provided at least between an inner wall of a storage portion and a smoothing capacitor and between the inner wall of the storage portion and a resistor, so as to be formed integrally, and heat dissipation and vibration protection for the smoothing capacitor and the resistor can be made by the cast resin. Thus, a dedicated assembly process for a structure for heat dissipation and vibration protection for the resistor is not needed, so that the cost is reduced. In addition, reliability of heat dissipation and vibration protection for the discharge circuit is ensured more easily as compared to a conventional method of pressing only one surface of the resistor to the housing by means such as screw fastening.
