摘要

PROBLEM TO BE SOLVED: To provide a permanent magnet assembly having a high magnetic attraction force. ;SOLUTION: This denture stabilizing permanent magnet assembly has a permanent magnet, a case of a corrosion resistance magnetic substance having a recess for housing the permanent magnet, and a shield plate of corrosion resistance magnetic and non-magnetic substances for concealing the permanent magnet and preventing the exposure thereof from the opening of the recess of the case. In this case, an inner yoke member of a magnetic substance having higher saturation magnetic flux density than the case has is provided between the permanent magnet and the case.;COPYRIGHT: (C)1998,JPO
