ABSTRACT:
The present invention relates to a fastener means comprising an attracting member A with a permanent magnet 1 and an attracted member B with a ferromagnetic element 110 to be attracted by the former member. To assure easy and stable attraction between the members A and B when they are respectively fixed to a pair of objects C and C' disposed in an intersecting relation, the members A and B include planes and e' that are parallel to each other when the members are attracted. Alternatively, the main attraction surfaces a' and/or b' of the members A and B include a plane d and/or d' within a virtual plane D that intersects the fixing surfaces of the objects, or the attracting member A and/or the attracted member B are fixed to the object with an inclination, so that the members A and B can be held stably attracted to each other without being subject to external force.
