Abstract
A gate valve includes a valve plate and a valve rod that are detachably connected along a rod axis by screwing a connecting screw in a screw hole formed at an end of a valve rod through a screw insertion hole formed in the valve plate. The valve plate includes a contact portion that is in contact with the connecting screw. When the connecting screw is loosened to detach the valve plate from the valve rod, the valve plate is displaced along the rod axis together with the connecting screw via the contact portion to move to a valve-plate detaching position at which the connecting screw comes completely out of the screw hole of the valve rod. Accordingly, the valve plate can be detached from the valve rod easily and reliably even if the valve rod is tightly inserted in the valve plate mounting hole.
