A fluid controller comprises a pivotal member pivotally movable about the axis of a horizontal pin, a pair of rollable rollers rotatably supported by the lower end of the pivotal member and having an axis in parallel to the axis of the horizontal pin, a slope provided by the upper surface of a bonnet for allowing each roller to roll therealong in a plane orthogonal to the axis of the roller, and a stopper supported by the pivotal member so as to be movable between a position to engage with a valve stem and a position to be out of engagement therewith. The pivotal member is pivotally moved to roll the rollers along the slope and move the roller-supporting pivotal member upward or downward with the rolling movement, whereby the horizontal pin is raised or lowered.
