Abstract
A chainsaw (electric working tool) includes a body case; a cutting part (working implement); and a motor, wherein the motor is mounted in a cooling route in the body case; an intake communicating with the cooling route is opened on the body case; an air filter is housed between the intake and the cooling route; the body case has a filter insertion/extraction hole through which the air filter can be inserted and removed; the intake is opened on the outer surface of the body case; and the filter insertion/extraction hole is arranged at a portion other than that of the intake so that the motor can be efficiently cooled, dust hardly enters the cooling route, and maintenance can be easily performed.
