Abstract
The invention is directed to a portable power working machine in which a casing has a side surface in which a suction port is provided. A block prevention guard is attached to the side surface of the casing. The block prevention guard comprises a top surface opening formed in the block prevention guard to at least partially overlap the suction port. The block prevention guard further comprises a plurality of legs standing from the side surface of the casing to maintain the top surface opening at a distance from the side surface. In addition to the top surface surface, an air flow window is formed between two adjacent legs in the circumferential direction of the top surface opening.
