Abstract
A valve device includes a valve seat forming member, a case, a first O-ring, and a second O-ring. The valve seat forming member is fit into a passage defining and forms a valve seat. The case houses an electromagnetic solenoid and is connected to the passage defining member. The first O-ring is interposed between an inner circumferential surface of the passage defining member and an outer circumferential surface of the valve seat forming member. The first O-ring prohibits the fluid from flowing through a space between the passage defining member and the valve seat forming member when the main valve body seats on the valve seat. The second O-ring is interposed between the case and the passage defining member. The second O-ring prohibits the fluid from flowing from the passage to an outside of the passage defining member.
