PROBLEM TO BE SOLVED: To provide a solenoid valve capable of improving a degree of freedom in the shape of a valve seat member.SOLUTION: A first switch valve 15 (solenoid valve) includes a first valve seat member 140 and a second valve seat member 150 fixed in a fixed core 110, a valve element member 170 disposed between the first valve seat member 140 and the second valve seat member 150, and a spring member 180 disposed between the valve element member 170 and the second valve seat member 150. The valve element member 170 includes a first valve portion 172 and a second valve portion 173 disposed on a main body portion 171 in a projecting manner. The first valve portion 172 is seated on a valve seat face 142 of the first valve seat member 140 by energization force of the spring member 180. By pressing out the valve element member 170 by a movable core 120, the first valve portion 172 is separated from the first valve seat member 140, and the second valve portion 173 is seated on a valve seat face 152 of the second valve seat member 150. Seal diameters of the first valve portion 172 and the second valve portion 173 are different from each other.SELECTED DRAWING: Figure 3

    【課題】弁座部材の形状の自由度を高めることができる電磁弁を提供する。【解決手段】第一切替弁15(電磁弁)であって、固定コア110内に固定された第一弁座部材140および第二弁座部材150と、第一弁座部材140と第二弁座部材150との間に配置された弁体部材170と、弁体部材170と第二弁座部材150との間に介設されたばね部材180と、を備えている。弁体部材170は、本体部171に突設された第一弁部172および第二弁部173を備えている。ばね部材180の付勢力によって、第一弁部172が第一弁座部材140の弁座面142に着座している。可動コア120によって弁体部材170が押し出されることで、第一弁部172が第一弁座部材140から離間して、第二弁部173が第二弁座部材150の弁座面152に着座する。第一弁部172と第二弁部173とのシール径が異なるように構成されている。【選択図】図3
