PROBLEM TO BE SOLVED: To easily clean the inside of a classifying rotor and a gap between the classifying rotor and a fine powder discharge part of the air current type classifier. SOLUTION: A motor 5 connected to a classifying rotor 3 in series is held by a circular holder 8 and supported by a cylindrical socket 6 fixed in the casing 1b in freely detachable manner while the position in the axial direction is made adjustable, so that it is made possible to clean the inside of the classifying rotor 3 of the air current type classifier and the gap between the classifying rotor 3 and a fine powder discharge part 4 and at the same time, it is made possible to easily adjust the gap between the classifying rotor 3 and the fine powder discharge part 4 when the motor 5 to which the classifying rotor 3 is connected is installed again after the cleaning.
