To provide a solenoid valve enabling easily adjusting a position of a movable member, as an example.SOLUTION: A solenoid valve includes: a housing provided with an internal flow channel; a seat disposed in the housing and provided with a first flow channel included in the internal flow channel; a movable member positioned inside the housing, movable with respect to the seat, closing the first flow channel by contacting with the seat, and causing the first flow channel to communicate with a second flow channel included in the internal flow channel by being separated from the seat; a coil generating magnetic field for energizing the movable member toward the seat by application of electric current; and an energization member which energizes the movable member in a direction separating from the seat by elastic force, and in which a spring constant at a time when the movable member is positioned in a first section farther from the seat with respect to the first position, is lower than a spring constant at a time when the movable member is positioned in a second section closer to the seat with respect to the first position.SELECTED DRAWING: Figure 2

    【課題】一例として、可動部材の位置を調整しやすい電磁弁を得る。【解決手段】実施形態に係る電磁弁は、内部流路が設けられた筐体と、前記筐体に設けられ、前記内部流路に含まれる第1の流路が設けられたシートと、前記筐体の内部に位置し、前記シートに対して移動可能であり、前記シートに接触することで前記第1の流路を塞ぎ、前記シートから離間することで前記内部流路に含まれる第2の流路に前記第1の流路を連通させる、可動部材と、電流を流されることで前記可動部材を前記シートに向かって付勢する磁界を発生させるコイルと、前記可動部材を前記シートから離間する方向に弾性力により付勢し、前記可動部材が第1の位置よりも前記シートから遠い第1の区間に位置するときのバネ定数が、前記可動部材が前記第1の位置よりも前記シートに近い第2の区間に位置するときのバネ定数よりも低い、付勢部材と、を備える。【選択図】図2
