Provided is a portable power working machine that is designed to suppress mixing of dust into air sucked into an air intake system of an air-cooled internal combustion engine mounted as a driving power source for working units, for example, and reliably prevent an air cleaner provided to the air intake system of the internal combustion engine from being clogged with dust, and thus eliminate the necessity of frequently cleaning the air cleaner. An air intake port of an air intake passage is arranged on the opposite side of the internal combustion engine with respect to a straightening passage formed around a cooling fan, so that, of the air released from a discharge port of the straightening passage, at least part of air released toward the opposite side of the internal combustion engine with respect to the straightening passage is taken into the air intake passage via the air intake port. |
