PROBLEM TO BE SOLVED: To provide a power tool with an air-cooling mechanism having excellent waterproofness and dust resistance.SOLUTION: A power tool with an air-cooling mechanism includes: a body side air-cooling mechanism 40 which is provided in a power tool body 30 storing an electric motor 32 and includes a first ventilation passage 41 disposed so that it can exchange heat with the electric motor 32, an inlet port 42 formed to be communicated with the first ventilation passage 41, and an exhaust port 43 formed to be communicated with the first ventilation passage 41; and a cooling side air-cooling mechanism 60 which is provided in a cooling device 61 with cooling means 70 and includes a second ventilation passage 62 disposed so that it can exchange heat with the cooling means 70, a suction port 65 formed to be communicated with the second ventilation passage 62, and a supply port 66 formed to be communicated with the second ventilation passage 62. The inlet port 42 is connected to the supply port 66 by a supply duct 80 and the exhaust port 43 is connected to the suction port 65 by an exhaust duct 82 so as to form a circulation space in which the body side air-cooling mechanism 40 is communicated with the cooling side air-cooling mechanism 60. In the circulation space, air blowing means 72 is provided to circulate air in the circulation space. |
