Such a protrusion 218 can reliably separate the movable portion 216 from the adjacent center core 72 and side core 74 corresponding to the movable portion 216, and the movement of the main body portion 214 is more reliably allowed without being hindered. In addition, when filling the reactor case 10 containing the coil assembly 30 with the filler M, the fluid filler M in the middle of filling is in contact with the protruding portion 218 and the adjacent center core 72 and side core corresponding thereto. 74, the fluidity of the filler M is increased and the wearability of the filler M is improved, and the coil assembly 30 of the coil assembly 30 is interposed via the void. It can penetrate inside. Further, the protruding portion 218 is tapered so that the upper end portion thereof is tapered in consideration of improving workability in which the center core 72 is lowered and placed and accommodated in the corresponding side core accommodating portions 102 and 202.
