PURPOSE: A magnetic force absorber using an ND(neodymium) magnet is provided to prevent oxidation of the ND magnet and smooth the rotation of a rotator, thereby minimizing the volume and weight of the magnetic force absorber and maximize the yield of the absorbed magnetic force. CONSTITUTION: A magnetic force absorber using an ND(neodymium) magnet includes a main body(1), front, intermediate and rear magnetic pole elements(2,2') mounted in the main body and formed relatively thick, a connecting pin(3) fitted in a plurality of inserting grooves(2'") formed on upper and lower parts of the magnetic pole elements and corresponding inserting grooves(2") formed at both sides of an interval maintaining element(5), a rotator case(6) fitted in the interval maintaining element and having a partition plates(6"), an ND magnet(7) formed with a solid oil film layer(7") on a surface and inserted between the partition plates of the rotator case, colloid oil storage chamber(8) formed at parts of the magnetic pole elements or a non-magnetic element(4) contacting the ND magnet, and an oil storage chamber(6") formed between the rotator case fitted in the interval maintaining element and a lid plate(5").
