<p><P>PROBLEM TO BE SOLVED: To provide a surface treating device capable of performing a rough surface treatment according to a magnitude of a rotary magnetic field by preventing magnetic abrasives from being accumulated at a longitudinal end of a treated material. <P>SOLUTION: This surface treatment device 1 includes a cylindrical housing tank 9, in which a developing sleeve 132 and a magnetic abrasive 65 as treated materials are housed; an electromagnetic coil for generating a rotary magnetic field along a circumferential direction of the housing tank 9; and a sealing plate 56 as a partition wall provided near a longitudinal end of the developing sleeve 132 and blocking the inside of the housing tank 9 along an axial direction. Furthermore, the surface treatment device 1 includes a cylindrical body 81, which is provided with the end of the developing sleeve 132 and the sealing plate 56 inside the housing tank 9, and is rotated in the same direction as the rotary magnetic field relative to the housing tank 9 in the rough surface treatment. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
