PROBLEM TO BE SOLVED: To provide an electromagnetic valve which can secure a pressure-insertion holding force when constituting the electromagnetic valve by fixing a plurality of members by pressure-insertion.SOLUTION: An electromagnetic valve 7 comprises: a coil 17 which generates a magnetic field at electricity-carrying; a cylinder 18 which is arranged at an internal periphery of the coil, and composed of a cylindrical member which is formed of a non-magnetic body; a core 19 arranged at one end side of the cylinder; a valve body 21 which is movably arranged in the cylinder along an axial direction of the cylinder so that one end side opposes the core, and has a valve part at the other end side; a pressure-inserted member 23 having a cylinder part which is liquid-tightly connected to the cylinder; and a pressure-insertion member 24 which has a seat part 33 separable from a valve body, and is pressure-inserted into the cylinder part. The rigidity of the pressure-insertion part is set lower than the rigidity of the pressure-inserted member.SELECTED DRAWING: Figure 1
【課題】複数の部材を圧入により固定して電磁弁を構成する際、圧入保持力を確保可能な電磁弁を提供すること。【解決手段】電磁弁7では、通電時に磁界を発生するコイル17と、コイルの内周に配置された非磁性体の筒状部材からなるシリンダ18と、シリンダの一端側に設けられたコア19と、一端側がコアに対抗するようシリンダ内にシリンダの軸方向に沿って移動可能に配置され、他端側に弁部を備えた弁体21と、シリンダに液密に接続した筒部を有する被圧入部材23と、弁体と切離可能なシート部33を有し筒部内側に圧入される圧入部材24と、を備え、圧入部材の剛性を被圧入部材の剛性よりも低くすることとした。【選択図】図1
