PROBLEM TO BE SOLVED: To reduce a leakage magnetic flux interlinked with a coil.SOLUTION: On an end surface 21e of a first leg part 21b, a first interposed part 21f interposed between a first gap 41 and a coil 30 is protruded. On an end surface 22e of a second leg part 22b, a second interposed part 22f interposed between a second gap 42 and the coil 30 is protruded. Since a leakage magnetic flux M2 generated around the first gap 41 and the second gap 42 is interlinked with the first interposed part 21f and the second interposed part 22f, the leakage magnetic flux M2 generated around the first gap 41 and the second gap 42 is less likely to be interlinked with the coil 30.SELECTED DRAWING: Figure 2 |
