发明名称 Inverter cover for motor-driven compressor
摘要 An electric compressor includes an inverter cover. The inverter cover has a metal plate that is arranged to cover an inverter (a circuit board). The metal plate has bolt insertion holes, through which metal bolts for fixing the inverter cover to a suction housing are passed. The head of each bolt contacts a flange portion, which is the periphery of the corresponding bolt insertion hole. The inverter cover is formed of plastic by being molded in a mold, using the metal plate as a core.
