PROBLEM TO BE SOLVED: To improve mutual positioning accuracy by preventing permanent magnets which are attracted to each other, from being displaced from each other in a direction orthogonal to pole surfaces of the permanent magnets.SOLUTION: A mechanical element comprises a first permanent magnet unit U1 in which a pair of permanent magnets 1 each having an N pole surface and an S pole surface is coupled while making their N pole surfaces opposite to each other with a yoke 3 consisting of a magnetic substance interposed therebetween; and a second permanent magnet unit U2 in which a pair of permanent magnets 1 each having an N pole surface and an S pole surface is coupled while making their S pole surfaces opposite to each other with a yoke 3 consisting of a magnetic substance interposed therebetween. The first permanent magnet unit U1 and the second permanent magnet unit U2 are disposed while making outer side faces on which an outer peripheral surface of the yoke 3 constituting a boundary part 2 of a pair of permanent magnets 1 in each of the units U1 and U2 appears, opposite to each other. In an arrangement state where the first permanent magnet unit U1 and the second permanent magnet unit U2 are arranged, the outer peripheral surfaces of the yokes 3 of the units U1 and U2 are made closer and attracted to each other.SELECTED DRAWING: Figure 2 【課題】 吸着し合う永久磁石同士の極面に直交する方向の互いのずれを防止して、互いの位置決め精度の向上を図る。【解決手段】 Ｎ極面及びＳ極面を有した一対の永久磁石１を、これらのＮ極面同士を磁性体からなるヨーク３を介して対峙させて結合した第１永久磁石ユニットＵ１と、Ｎ極面及びＳ極面を有した一対の永久磁石１を、これらのＳ極面同士を磁性体からなるヨーク３を介して対峙させて結合した第２永久磁石ユニットＵ２とを備え、第１永久磁石ユニットＵ１及び第２永久磁石ユニットＵ２は、該各ユニットＵ１，Ｕ２における一対の永久磁石１の境界部２を構成するヨーク３の外周面が現れる外側面同士を対面させて配置され、第１永久磁石ユニットＵ１及び第２永久磁石ユニットＵ２が配置された配置状態において、該各ユニットＵ１，Ｕ２の上記ヨーク３の外周面同士が接近吸着するようにした。【選択図】図２
