PROBLEM TO BE SOLVED: To provide a method of application of a brake by which the rotational speed of a grinder having a high-mass rotor can be reduced within a time as short as possible. SOLUTION: Provision with a brake at a shaft 12r on the drive side of a gear mechanism 16 so as to reduce the rotational speed of the drive shaft exerts effects of reducing the rotational speed of an output shaft 20 that drives a rotor 24 of a grinder connected via the gear mechanism 16 thereto.
