Power working machine

The invention provides a technique capable of making it difficult for foreign matter to be sucked in from an air suction port. According to one aspect of the present invention, a powered working machine is provided. The power working machine is provided with a working part, a driving part, a main body part and an air blowing part. The working part acts on a working object. The drive unit drives the working unit. The main body part has a bottom surface part, an air suction port and an air exhaust port, and is provided with a containing space for containing the driving part and a ventilation path which leads from the air suction port to the air exhaust port through the containing space. The air blowing part generates an air flow toward the exhaust port in the ventilation path. The suction port opens in a direction having a vertically downward component in a first state in which the power work machine is placed such that the bottom surface faces the horizontal plane. 本发明提供一种能够使异物难以从吸气口被吸入的技术。根据本发明的一种方式，提供一种动力作业机
