作動表示機構。 A cylinder in which a valve body that opens and closes a flow path by contacting and separating from a valve seat in the body, and a valve stem connected to the valve body at one end are inserted in the body so as to be freely displaceable in the axial direction; A display rod equipped with a display means is inserted into the cylinder so as to be freely displaceable in the axial direction, and has a case separated from the cylinder by a partition wall, and is made of a magnetic material and faces each other with the partition wall in between. At least one of the other end of the valve stem and one end of the indicator rod is magnetized, and the indicator rod is urged by a spring member in a direction opposite to the direction of the magnetic force due to the magnetization. Valve operation display mechanism.
