Check valve a pressure differential is provided with a valve body assembly (valve body) (3A) by the contact / release relative to the valve seat in order to obtain good sealing properties in a high-pressure state and a low pressure both in communication / block the fluid passage ( in the on-off valve device for fluid) (1A), the valve body assembly (3A) has a valve body 10, and a low-pressure seal portion 12 made of soft material, made of a harder material than the low-pressure seal portion 12 If the differential pressure of the high-pressure seal portion the upstream passage of the fluid passage 7 and the downstream-side passage (8) when provided, and the fluid passages are sealed off (13) of relatively low pressure is a low-pressure seal portion 12, a protrusion ( by adhesion to 6) being blocked is the fluid passage, when the differential pressure is a relatively high pressure, at the same time as the low-pressure seal portion 12 is compressively deformed by the differential pressure, the high-pressure seal portion 13 in the valve seat body 4 the fluid passage is blocked by close contact.
