Zusammenfassung:PROBLEM TO BE SOLVED: To suppress failure such as yellow generation of flame of a cooking stove burner or abrupt spread of flame resulting from instantaneous change of the position of a valve body of a latch type solenoid valve disposed in a gas flow passage.SOLUTION: A movable magnetic body 52 moving in a valve opening direction or a valve closing direction in a cylindrical storage part 83 includes a second spring 82 configured to perform energization toward the inner peripheral surface of the storage part 83, and a spherical body 81 energized by the second spring 82 and contacting with the inner peripheral surface. The movement speed of the movable magnetic body 52 is suppressed by friction resistance between the spherical body 81 of the movable magnetic body 52 and the inner peripheral surface of the storage part 83.SELECTED DRAWING: Figure 6 【課題】ガス流路に配設されるラッチ式電磁弁の弁体の位置が瞬時に変化することに起因するコンロバーナの火炎のイエロー発生や炎の急激な広がりといった不具合を抑制する。【解決手段】筒状の収容部83内を開弁方向及び閉弁方向へ移動する可動磁性体52は、収容部83の内周面へ向けて付勢する第2スプリング82と、該第2スプリング82によって付勢されて前記内周面に当接する球体81とを備えており、可動磁性体52の移動速度を、該可動磁性体52の球体81と収容部83の内周面との間の摩擦抵抗によって抑制するようにしている。【選択図】図6
