<p>PROBLEM TO BE SOLVED: To provide an electric tool device which can perform module assembly, and prolong the service life of the device subjected to high stress impacts. SOLUTION: In this electric tool device comprising an internal rotor 5 having a magnetic pole 4 and an external stator 8 having an electromagnetic coil 7 connected to an inverter of a control electronic device 6 in order to perform the striking drive by at least partially rotating a tool with a pneumatic striking mechanism 2, and driving the striking mechanism 2 by an electronically rectifying electric motor 3 via a transmission configuration group 9, a drive end side of a rotor shaft 10 is pivotally supported by the transmission configuration group 9, and in a drive side of the rotor shaft 10, the magnetic pole 4 protruded so as to be engaged with the stator 8 is inserted coaxially with the stator 8. A large number of relatively arranged grooves and channels 21 for a refrigerant pipe are formed in a motor housing 16, a transmission housing wall 15a on the side of the motor housing, and a housing wall 18a of an electronic device.</p> |
