In each of the soundproofed engine generators, the position at which the power generator body is coupled to the crank shaft is located at the end part on the crank shaft. In the soundproofed engine generator of the inverter type, the inverter unit is opposed to the power generator body at a position just upstream of the power generator body. Accordingly, when the inverter unit and the power generator body are removed, a continuous, long and large space for receiving the power generator body can be secured within the soundproof cover.
