Abstract: PURPOSE: A machined burr removing device improves the precision of a machining of a brush holder and improves the performance of a regulator. CONSTITUTION: A cutting edge fixing member where a cutting edge(61) is fixed is vertically moved to coincide the position of the cutting edge(61) to the height of a brush slot(22). Thus, height adjusting bolts installed on a left and a right vertical supporting panels(92a,92b) fixed on a base(40) are rotated. Then, a lower moving panel is moved to the width direction of the base(40). At the moment, the top surface of the lower moving panel forms a slant surface and the cutting edge fixing member contacted on the lower moving panel has a slant surface corresponding to the slant surface of the lower moving panel. Therefore, the cutting edge(61) is ascended/descended because the lower moving panel moving transversally pushes up the cutting edge fixing member. Particularly, the cutting edge fixing member is movable only vertically by being restrained by the vertical supporting panels(92a,92b) at both sides thereof.
