To provide a solenoid valve capable of curbing a fluctuation in a flow passage area even when subjected to external input of oscillation and to provide a damper capable of exerting targeted damping force.SOLUTION: A solenoid valve V comprises: a holder 6 which has a cylindrical port 6a; spool 7 which is inserted in the holder 6 so as to be able to reciprocate in an axial direction; an energizing spring 8 which energizes the spool 7 in one of moving directions of the spool 7; a solenoid 9 which can apply propulsion force to the spool 7 so as to move the same in the other of the moving directions of the spool 7; a liquid pressure locking chamber RC which is installed between the holder 6 and the spool 7 and blocks movement of the spool 7 with respect to the holder 6 when closed; a shutter 17 which can be reciprocated in directions identical with the moving directions of the spool 7 and switches the liquid pressure locking chamber RC to be opened or closed; and a shutter spring 18 which energizing the shutter 17 so as to set the same at a position to open the liquid pressure locking chamber RC.SELECTED DRAWING: Figure 2

    【課題】外部からの振動入力があっても流路面積の変化を抑制できる電磁弁および狙い通りの減衰力を発揮できる緩衝器の提供である。【解決手段】電磁弁Vは、筒状でポート6aを有するホルダ6と、ホルダ6内に軸方向に往復動可能に挿入されるスプール7と、スプール7をスプール7の移動方向の一方へ向けて付勢する付勢ばね8と、スプール7へスプール7の移動方向の他方へ向けて移動させる推力を付与可能なソレノイド9と、ホルダ6とスプール7との間に設けられて閉鎖されるとホルダ6に対するスプール7の移動を抑制する液圧ロック室RCと、スプール7の移動方向に一致する方向へ往復動可能であって液圧ロック室RCの開放と閉鎖を切換えるシャッタ17と、シャッタ17を付勢して液圧ロック室RCを開放する位置にシャッタ17を位置決めするシャッタばね18とを備えている。【選択図】図2
