Japanese Patent JP6713663
Kind Code:
B2
Abstract:
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
