  • the lines of magnetic force flowing into the one end face 41 forming the S pole facing the adsorption side 4 are non-magnetic. It flows in through the cap yoke C 1 made of a magnetic material, avoiding the cap spacer C 2 made of a body. Therefore, by the action of the cap spacer C2, it is possible to minimize the short circuit of the magnetic force lines flowing directly to the first magnetic member 2 without leaving the attraction side surface 4 from the second magnetic member 2. As a result, when the one end face 4 1 and the suction side face 4 are made to coincide with each other without using the cap yoke C 1, the magnetic attraction force is not inferior.
  • the following means are conceivable as means for preventing and preventing other magnetic pole-dispersed opposed magnetic actuators.
  • the magnetic * -dispersion opposed magnetic attachment comprises the first magnetic member or the second magnetic member formed of a permanent magnet having the same magnetic pole directed to the attraction side ⁇ .
  • the thickness of the object to be adsorbed can be made thinner than the thickness of the magnetic pole dispersion opposed magnetic attachment according to the present invention, and even when the thickness of the object to be absorbed is extremely thin, sufficient magnetic properties can be obtained. A suction force is obtained.

Abstract

La présente invention concerne une fixation magnétique très mince, qui possède une force d'attraction magnétique suffisamment forte. Cette fixation magnétique est constituée, par exemple, par plusieurs aimants permanents (11-14) dotés de faces inférieures (4) exerçant une attraction et disposés à certains intervalles, une matière magnétique douce (21) qui couvre les faces latérales des aimants (11-14) et donne avec eux une forme analogue à une plaque, et un élément (3) de recouvrement qui couvre les faces supérieures des aimants (11-14) et qui est fait d'une matière magnétique douce. Les faces inférieures (4) exerçant une attraction des aimants (11-14) sont magnétisées de manière que leurs pôles soient identiques, nord ou sud. De nombreuses lignes de force magnétiques en boucle sont formées par chaque aimant (11-14).
