PROBLEM TO BE SOLVED: To reduce a dimension of a valve body in a radial direction.SOLUTION: An electromagnetic valve comprises: a valve body 100 having a penetration hole 112; a valve disc 104 which slides in the penetration hole 112, and is seated on a valve seat; a first communication hole 115 which is formed in a direction orthogonal to an axial direction of the valve body 100, and makes the penetration hole 112 in the valve body 100 communicate with a passage outside the valve body 100; and an inner filter 116 which prevents the intrusion of foreign matters to the valve seat side from the first communication hole 115. The inner filter 116 is arranged between an internal face of the penetration hole 112 and an external peripheral face of a valve rod 106 at a position facing the first communication hole 115.
【課題】バルブボディの径方向の寸法を小さくすること。【解決手段】貫通孔112を有するバルブボディ100と、貫通孔112内を摺動すると共に、弁座に着座する弁体104と、バルブボディ100の軸方向と直交する方向に形成されてバルブボディ100内の貫通孔100とバルブボディ100外の通路とを連通させる第1連通孔115と、第1連通孔115から弁座側に異物が進入することを防止する内フィルタ116とを備え、内フィルタ116は、第1連通孔115に臨む位置で貫通孔112の内面と弁ロッド106の外周面との間に配置されている。【選択図】図4
