A compact and light-weight portable electric router (1, Fig 1) produced at a low cost and capable of providing high cutting efficiency with low noise. A radial fan (20) includes a cylindrical hub (21) functioning as an attachment portion to a motor shaft (16), a plurality of fan blades (22) having parts connecting to the hub (21), and a ring like guide section (23) connected to the hub (21) through the fan blades (22). An annular weight (24) is connected to the guide section (23) at a radially outer side of the guide section (23). The weight (24) serves as a restriction section for restricting backflow of air from a discharge side to a motor side. |
