Abstract
A fluid controller includes an automatic opening-and-closing device configured to move a valve rod upward and downward, and a manual opening-and-closing device configured to move the valve rod upward and downward by a manual operation. The manual opening-and-closing device includes a cylindrical handle supported by a casing so as to be rotatable and not to move upward and downward, and a cylindrical operating member screwed into a female screw of the handle and configured to move upward and downward with a rotation of the handle. The operating member is apart from a piston of the automatic opening-and-closing device in a vertical direction in an automatic operation. The piston is moved by the operating member which moves upward in association with the rotating operation of the handle in a manual operation in an opposite direction from the opening state brought by the automatic opening-and-closing device.
