PROBLEM TO BE SOLVED: To perform easy adjustment of the motion amount of an armature.SOLUTION: A motion amount adjustment mechanism 170 is constituted of a core 110, a supporting part 140, a collar 150 and a spacer 160. A collar male thread part 152 and a core female thread part 113 are engaged in thread to be able to relatively advance or retract. Upon rotation of the collar 150, the core female thread part 113 advances in thread in respect to the collar male thread part 152 and along with this motion, the core 110 also moves. The other end part of the collar 150 protrudes out from an opposite side of the core 110 facing to a drum 10 and is inserted into a spacer cylinder hole 161. Each of first collar flat surfaces 153, 153 of one set in three sets of first collar flat surfaces 153, 153 opposing to each other at the other end of the collar 150 oppositely faces an inner flat surface 163 of a spacer 160. Upon rotation of the spacer 160, inner flat surfaces 163, 163 of the spacer 160 are engaged with corners of the other end part of the collar 150, and then the collar 150 is also rotated.SELECTED DRAWING: Figure 6

    【課題】アマチュアの移動量を容易に調整する。【解決手段】移動量調整機構170は、コア110と、支持部140と、カラー150と、スペーサ160と、から構成されている。カラー雄ねじ部152とコア雌ねじ部113とが、相対的に螺進退可能に螺合している。カラー150を回転させると、カラー雄ねじ部152に対しコア雌ねじ部113が螺進退し、これに伴って、コア110が移動する。カラー150の他端部は、コア110のドラム10側の反対側から突出して、スペーサ筒孔161に挿入されている。カラー150の他端部における互いに対向する3組の第1カラー平面153,153の内のいずれか1組の第1カラー平面153,153のそれぞれが、スペーサ160の内平面163と対向する。スペーサ160が回転すると、スペーサ160の内平面163,163が、カラー150の他端部の角部と係合し、カラー150も回転する。【選択図】図6
