Soundproof type engine working machine

A soundproof type engine working machine comprising a soundproof casing containing therein an engine and a working machine such as for example a dynamo driven by the engine and situated one behind another in the rotary axis direction. In this engine working machine, a main air inlet port into the soundproof casing is formed in a bottom portion of the soundproof casing and at the side where the working machine is situated, a fan for cooling the working machine is mounted to the working machine and a fan for cooling the engine is mounted to the engine, respectively, and a fan cover for covering the engine cooling fan is communicated with a duct covering a cylinder portion of the engine and an exhaust muffler and opened up outside of the soundproof casing at an end portion thereof, a cooling air by the working machine cooling fan being introduced to the duct after the air cooled the working machine. An oil pan cooling air passage is disposed along an oil pan portion of the engine. This oil pan air passage is communicated at its one end with the fan cover and is permitted to penetrate at its other end through a bottom portion of a soundproof casing and opened up outside of the casing. The engine is provided with a recoil starter mounting portion. Within the casing, a battery installing space is defined adjacent to a space occupied by the recoil starter mounted to the recoil starter mounting portion.
