PROBLEM TO BE SOLVED : To provide a magnet roller which can prevent an adhesive from running out and dripping, when a rare-earth magnet is attached to the groove part of a cylindrical magnet formed body across an adhesive.SOLUTION : The magnet roller 10 has at least one recessed groove part 2 in which other members can be embedded in a part corresponding to the pole of the cylindrical magnet formed body 1 constituted of a ferrite-based plastic magnet. A long magnet formed body 3 having magnetic force greater than that of the plastic magnet is disposed in the groove 2 across an adhesive. The long magnet formed body 3 has a recessed part 3a opened on the face in contact with the surface of the groove 2 so as to prevent the adhesive from running out. The long magnet formed body 3 also has wall parts 3b provided so as to surround the outer periphery of the recessed part 3a to prevent the adhesive from dripping.COPYRIGHT : (C)2007, JPO&INPIT |
