<P>PROBLEM TO BE SOLVED: To improve the assembling workability of the peripheral portion of an inverter as well as preventing lead terminals for connecting electric parts with the control circuit board of an inverter from breaking due to vibrations while effectively dissipating the heat from exothermic electric parts mounted on the control circuit board. <P>SOLUTION: An IGBT 41, being an exothermic electric part, mounted on the undersurface of a lower board 25B acting as the control circuit board of the inverter 21 is allowed to abut against a heat dissipating plane 31 provided on the inside wall of an inverter box 23 provided on the periphery of a housing 2 and thereby the heat of the IGBT 41 is dissipated to a side of the housing 2. Besides, between the lower board 25B and the IGBT 41, a spacer member 45 is interposed which fills a space between both these lower board 25B and IGBT 41 and further has the rigidity enough to eliminate the nearing and leaving displacement between the lower board 25B and the IGBT 41. <P>COPYRIGHT: (C)2011,JPO&INPIT |
