Zusammenfassung:PROBLEM TO BE SOLVED: To enhance operability of an electric tool by making a DC brushless motor compact in size in a machine length direction, thereby making the electric tool compact in machine length in the electric tool such as an impact driver employing the DC brushless motor as a drive source.SOLUTION: Machine length of a DC brushless motor M is shortened by locating a bearing 57 for supporting a rotating shaft 53 of a rotor 50 on an inner peripheral side of an electric insulating member 62 of a stator 60.
