PROBLEM TO BE SOLVED : To provide an undersized and economical magnet holder constituted substantially of only a main body made of a rare earth metal magnet, and a remover for simply removing the magnet holder.
SOLUTION : This magnet holder is constituted of only the rare earth metal magnet which has a magnetic field orientated in a disc-shaped or ring-shaped surface direction and changes the magnetizing direction by one half side in the surface direction. Alternatively, the rare earth metal magnet which has the magnetic field orientated and is magnetized in diametral direction, is used. For the remover, the rare earth metal magnet having a magnetic attraction force which is the same as or higher than the rare earth metal magnet constituting the magnet holder and of the same magnetic field orientation and magnetization type as the latter, is fitted to the tip of a gripping part in a freely rotating manner. Under this constitution, the magnet at the tip of the remover has its appropriate position regulated by rotation, when the remover gets close to the magnet holder. Consequently, the remover and the magnetic holder magnetically attract each other and the simple removal of the magnetic holder from an object to be displayed, can be achieved.
