To provide a fluid control valve which causes a valve body to reliably seat a valve seat and can exhibit valve closing function even when a valve shaft is inclined irrespective of a small-area seal surface and can reliably exhibit the valve opening function even upon cold time.

In a main valve 11 which controls fluid to be supplied, a valve body 11a and a valve shaft 11b are connected with a universal joint means 50, and the universal joint means 50 is composed of a spherical convex part 52 formed on the valve shaft 11b and a spherical concave part 53 which is formed on the valve body 11a and freely swingably holds the spherical convex part 52. Thereby, even when the valve shaft 11b is inclined, the valve body 11a can be reliably seated on the valve seat 12. Moreover, by virtue of the reliable seating, seal area of a seal member 54 to be stuck to the valve body 11a is decreased, residence of moisture on a seal surface can be suppressed and, therefore, even upon the cold time, the valve body 11a leaves seat and the valve opening function is not injured.
