Abstract
A fluid control valve device includes a seal part disposed to a valve seat of a housing. The seal part is elastically deformable and contacts a valve part when a fluid passage is closed. The seal part has a surface opposing the valve part, a first projection part projected from the surface toward an upper surface of the valve part, and a second projection part defined to surround the first projection part and projected from the surface toward the upper surface of the valve part. The second projection part is adjacent to the upper surface of the valve part than the first projection part is.
