<p>PROBLEM TO BE SOLVED: To provide an electric tool which makes permanent magnets unlikely to be dropped from a rotor and thereby enables use of a highly reliable brushless motor.SOLUTION: A brushless motor 8 is formed by a stator 24 and a rotor 25 and permanent magnets 53 are respectively inserted into multiple through holes formed at a rotor core 52 of the rotor 25. In a vibratory driver drill 1, the brushless motor 8 is stored in a body housing 10. A rear stopper 63 and a front stopper 64 which prevent the permanent magnets 53 from being removed from the through holes of the rotor core 52, are provided in the rotor 25.</p> |
