Therefore, in the opening / closing operation of the fluid control valve 10, the outer peripheral surface 26 of the valve body 20 is always in non-contact with the inner wall surface 16 of the housing 12. The contact and non-contact are repeated only at the contact portion between the tip portion 2 2 of the valve body 20 and the seal portion 18. Therefore, in the operation of the fluid control valve 10, there is almost no sliding between the valve body 20 and the housing 12, and the wear can be greatly suppressed.
