LOCK ACTUATOR
To provide a lock actuator having large holding power during deenergization, capable of preventing sticking force due to a reverse magnetic field during energization from generating and having excellent efficiency when switching maintenance and release.SOLUTION: A lock actuator 100 includes: an electromagnetic part 102 including a coil 110 arranged in the inside of a body 108; and a catch 104 attached to and detached from the electromagnetic part. The catch includes: a permanent magnet 128 arranged in the inside of a magnetic substance case 126; and a magnetic piece 130 arranged on the side of the electromagnetic part of the permanent magnet in the inside of the case and facing the body of the electromagnetic part. A gap L is provided between an end surface 140 of the magnetic piece and the case; during deenergization, the magnetic flux of the permanent magnet forms a first magnetic path Ra passing the body of the electromagnetic part through the magnetic piece; during energization, the magnetic flux of the coil forms a second magnetic path Rb passing the body without passing the catch; and the magnetic flux of the permanent magnet is switched from the first magnetic path to a third magnetic path Rc passing the case from the magnetic piece through the gap without passing the body.SELECTED DRAWING: Figure 1
【課題】非通電時の保持力が大きく、通電時に逆磁界による張り付き力が発生し難く、保持と解除の切り替え時の効率が良いロックアクチュエータを提供する。【解決手段】ロックアクチュエータ１００は、ボディ１０８の内部に配置されたコイル１１０を有する電磁部１０２と、電磁部に対して離着するキャッチ１０４とを備え、キャッチは、磁性体のケース１２６の内部に配置された永久磁石１２８と、ケースの内部で永久磁石の電磁部側に配置され、電磁部のボディに対面する磁性片１３０とを有し、磁性片の端面１４０とケースとの間にはギャップＬが設けられ、非通電時には、永久磁石の磁束が磁性片を介して電磁部のボディを通る第１の磁路Ｒａを形成し、通電時には、コイルの磁束がキャッチを通らずボディを通る第２の磁路Ｒｂを形成し、永久磁石の磁束は、第１の磁路から、ボディを通らずギャップを介して磁性片からケースを通る第３の磁路Ｒｃに切り替えられる。【選択図】図１
